Introduction

Field Programmable Gate Arrays (FPGAs) and Complex Programmable Logic Devices (CPLDs) are two types of programmable logic devices that allow engineers to implement custom digital circuits. Both offer flexibility and rapid prototyping capabilities for digital systems. However, there are some key differences between the two that make each more suitable for certain applications.

What is an FPGA?

An FPGA is an integrated circuit designed to be configured by the customer or designer after manufacturing. FPGAs contain programmable logic components called logic blocks and a hierarchy of reconfigurable interconnects that allow the logic blocks to be connected. Logic blocks can be configured to perform complex combinational functions or simple logic gates like AND and XOR gates.

FPGAs typically contain a large array of logic blocks and rich interconnect resources to implement very complex digital circuits. The programmable logic blocks and interconnects configuration is generally specified using a hardware description language like VHDL or Verilog.

Some key capabilities of FPGAs include:

• Implementing any digital circuit up to hundreds of thousands of gates
• Reconfigurability – circuits can be changed after manufacturing
• Rapid prototyping and design iteration
• DSP and math-intensive functions with dedicated DSP slices
• Parallel processing with a large number of logic blocks

FPGAs are commonly used for digital signal processing, software-defined radio, aerospace and defense systems, ASIC prototyping, medical imaging, computer vision, cryptography and other compute-intensive tasks. Leading FPGA vendors include Xilinx and Intel (formerly Altera).

What is a CPLD?

A CPLD or Complex Programmable Logic Device is also a programmable integrated circuit containing logic blocks and interconnects. However, CPLDs have a much simpler overall architecture compared to FPGAs.

CPLDs consist of a small number of macrocells connected through a programmable interconnect matrix. Each macrocell is more complex than a typical FPGA logic block and can implement medium-sized logic functions. The interconnect matrix provides routing between macrocells.

Some of the key characteristics of CPLDs are:

• Contains a few tens to hundreds of macrocells
• Each macrocell has wide input/output capability
• Interconnect is less flexible than FPGA routing
• Limited clocking and I/O resources compared to FPGAs
• Programming is via logic equations instead of hardware description languages

CPLDs are best suited for:

• Glue logic and interfacing between components
• Small to medium complexity logic implementation
• Cost-sensitive simple designs

Some examples applications of CPLDs include:

• Front panel button and LED interfacing
• State machine control logic
• Counter/timers
• Parallel data processing

Major CPLD manufacturers include Lattice Semiconductor, Microchip (formerly Atmel) and Intel (formerly Altera).

Key Differences Between FPGAs and CPLDs

Although both FPGAs and CPLDs are programmable logic devices, there are some key differences between the two architectures:

Logic Capacity

The most fundamental difference is logic capacity. FPGAs offer much higher capacity with hundreds of thousands of logic gates while CPLDs have hundreds to a few thousand gates.

For implementing complex digital circuits with large gate counts, FPGAs are preferable. CPLDs are suitable for simple glue logic functions.

Architecture and Flexibility

The overall architecture and configurability of both devices is very different. FPGAs have a sea of small logic blocks interconnected by a flexible routing structure. This allows very complex custom architectures to be realized.

CPLDs have a coarser overall architecture with a small number of larger macrocells connected by a simple interconnect structure. This limits the range of designs that can be implemented compared to FPGAs.

Design Entry Methods

FPGAs are configured using hardware description languages like VHDL or Verilog. This gives designers full control over the architecture and behavior.

CPLDs are programmed using logic equations that define the function of each macrocell. This is more restrictive than HDL-based design entry.

Performance

The abundant interconnect and separate memory blocks of FPGAs allow much higher performance for designs with lots of parallelism or requiring high memory bandwidth. Special DSP slices can accelerate signal processing algorithms.

CPLD performance is more limited in comparison due to the simpler architecture.

Cost

Owing to their architectural simplicity, CPLDs tend to be lower cost than FPGAs for smaller logic capacity needs. High-density FPGAs can be quite expensive.

Clock Management

FPGAs provide sophisticated clock management tiles that allow many clock domains with frequency synthesis and clock skewing. This is useful for complex synchronous digital circuits.

CPLD clock management capabilities are quite limited in comparison.

Development Tools

The design toolchains for FPGAs and CPLDs are very different. FPGA vendors offer advanced software for design simulation, timing analysis, layout, placement & routing and programming.

CPLDs are programmed using logic compilers that are simpler to use but offer less verification capability.

Summary of Differences

Application Differences

The architectural differences between FPGAs and CPLDs make them suitable for different classes of applications:

FPGAs are ideal for:

• Compute-intensive algorithms like video processing, encryption, bioinformatics
• Complex systems requiring high data throughput and parallelism
• Advanced interfacing protocols like PCIe, Ethernet, SATA
• Prototyping ASIC/SoC designs before tapeout

CPLDs are ideal for:

• Simpler glue logic, control logic and interfacing
• Low-cost designs not requiring advanced features
• Small form factor designs (CPLDs have smaller packages)

FPGA vs CPLD Example Designs

To better illustrate the differences in applications suited for FPGAs and CPLDs, let’s compare a few example digital systems typically implemented using each type of programmable logic device.

FPGA Design Examples

High-Speed Network Router

A network router for high-end infrastructure has the following requirements:

• Packet forwarding at up to 400 Gbps
• Routing table lookup using TCAM
• Traffic shaping algorithms
• Buffering with high memory bandwidth
• Multiple network interfaces up to 100Gbps

An FPGA would be an ideal fit for implementing a high-performance router like this. The flexible logic blocks and DSP slices can implement the data plane forwarding functions. Large embedded memory blocks provide packet buffering. The I/O blocks support high-speed interfaces like 100Gbps Ethernet.

Real-Time Video Processing

A real-time video processing pipeline has the following functionality:

• Pixel processor for image enhancement
• Motion estimation for video compression
• Image pyramid generation
• Neural network-based object detection

The highly parallel nature of video processing maps perfectly to an FPGA. The dedicated DSP blocks handle pixel processing and motion estimation. The FPGA’s logic fabric implements generate image pyramids efficiently in hardware. Theobject detection neural network can also be mapped to programmable logic.

Encryption Accelerator

An encryption accelerator card offloads processing for algorithms like AES, SHA, RSA from the host CPU. It requires:

• High-bandwidth I/O to transfer data
• Parallel encryption engines
• Low-latency request processing

FPGAs are widely used for encryption due to their performance benefits over software. The reconfigurable fabric implements parallel encryption pipelines to achieve very high throughput. Low-latency access to the encryption engines can also be guaranteed when using an FPGA compared to software.

CPLD Design Examples

LED Controller

An LED controller drives a set of eight RGB LEDs for mood lighting based on user input. It requires:

• Debounced button inputs for mode select
• PWM generation for LED intensity control
• LED enable signals

A small CPLD with eight to sixteen macrocells can easily implement the glue logic for the LED controller. The parallel I/O capability enables driving multiple LEDs simultaneously. Timers implemented in logic generate the PWM waveforms.

Motor Controller

An electric motor controller coordinates six motors. It requires:

• Individual speed and direction control for each motor
• Motor enable signals
• Position and speed feedback processing
• Analog voltage monitoring

The glue logic and interfacing in the motor controller maps well to a mid-size CPLD. Macrocells can generate the necessary control signals for enabling and driving each motor. Additional logic processes the feedback and monitor inputs.

SDRAM Controller

A simple SDRAM controller interfaces to a 64MB SDRAM with a 16-bit data bus. Key requirements are:

• SDRAM command timing
• Refresh cycle generation
• Bank/row/column addressing
• Data bus buffering

A CPLD can implement the basic timing and control functionality needed for the SDRAM controller using its predictable timing performance and parallel I/O capability. More advanced memory controllers are better suited for FPGAs however.

Choosing Between FPGAs and CPLDs

So when should you choose an FPGA over a CPLD, and vice versa? Here are some guidelines for selecting between the two types of programmable logic:

When to Use an FPGA

• For complex logic functions requiring thousands of gates/logic cells
• If DSP capabilities like multipliers are needed
• For designs requiring lots of memory and wide memory buses
• Fast processing of parallel data is required
• Multiple high-speed serial I/O standards are required
• HDL-based design entry is preferable
• Advanced debugging capabilities are desired

When to Use a CPLD

• Only simple glue logic or interfacing is needed
• Low cost is critical
• Small packaging is required
• Low power operation is prioritized
• Simple logic equations can specify the design adequately
• Minimal debugging capabilities are sufficient

For the vast majority of complex, high-performance designs FPGAs will be the best choice. CPLDs excel in simpler glue logic applications where their low cost and small form factor are beneficial.

Conclusion

FPGAs and CPLDs both provide user-programmable logic capability but are suited for very different types of applications. FPGAs offer higher logic density, more flexibility, advanced features and superior performance. CPLDs trade off capability for a simpler architecture, smaller footprint and lower cost.

Engineers should carefully consider the requirements of their application and determine which type of programmable logic device better suits their design needs. As a rule of thumb, FPGAs tackle complex logic problems requiring high data throughput while CPLDs handle simpler glue logic and interfacing tasks.

Understanding the architectural differences between FPGAs and CPLDs will ensure the best choice is made when starting a new programmable logic design. Both families offer unique benefits spanning a wide range of digital systems.

FPGA vs CPLD FAQ

Here are answers to some frequently asked questions about FPGA and CPLD differences:

Q: Can an FPGA replace a CPLD in a design?

Yes, an FPGA can readily implement the same functions as a CPLD owing to its greater logic density and flexibility. Replacing a CPLD with an FPGA may also allow you to add more functionality and performance.

Q: Do FPGAs and CPLDs require different CAD tools?

Generally yes. FPGA vendors provide advanced toolchains for simulation, synthesis, place and route, timing analysis and programming. CPLDs use simpler logic compilers and do not require intensive timing analysis.

Q: How do FPGA and CPLD programming differ?

FPGAs are programmed using hardware description languages like VHDL or Verilog. CPLDs are programmed by defining Boolean equations or state machines to specify logic functions.

Working with electronics can be a terrifying prospect for someone who has little to no experience. One needs to be competent in several different areas just to get started. Fortunately, some tools can help simplify the process, and with these tools, any beginner can get off the ground running.

Xilinx Spartan-7 FPGA boards‘ design is precisely for this purpose with features. For instance, being free from onboard power supplies and simple USB connections. It makes the task of getting started easier than ever before.

The boards are essential in creating many things, from simple LED projects to clocks to full-featured computers, and much more. Spartan-7s is facing criticism from those who believe there is little to offer those with the most limited needs despite their versatility. This notion stems from the fact that many people see them as a steppingstone towards something better. It seems like a common opinion amongst those who do not know why they would choose Spartan-7 over other FPGA boards.

The Arty family of Digilent boards aims to change this notion. These boards are perfect for a wide variety of FPGA projects and do not require heavily trained engineers to use or operate. These designs combine power and ease of use with the flexibility needed to create something great. They also integrate high-end FPGA features. For instance, Xilinx‘s 1.2TFLOPS Tri-core processors, the industry-standard BM3358 dual-core processor, and more into small form factor boards that people can use. At the same time, they learn FPGAs without feeling overwhelmed by the technology.

Product description

The first thing that people will notice is that the Arty boards are small, just 4.75 inches by 2.8 inches. This makes them perfect for projects within tight spaces where it would be impossible to fit something larger. Since these boards lack onboard power supplies, they are straightforward to use since we can power them through any micro-USB cable or adapter. This makes them great for projects that might need relocation frequently. We do not need a particular power source to power the board once everything is working correctly.

In addition to being small, the boards are relatively light, making them easy to carry around or carry in a case. With a weight of just Under 1.5 pounds, most people who use them will not even know that they are carrying around an FPGA board.

The boards have all the standard functionality you expect from a modern FPGA board. They include Xilinx’s DSP blocks, such as the CINCH mode, and PCR blocks, such as the DSPax2 and DSPz2 cores. This helps to ensure that those who use these boards will be able to create something truly amazing without compromising the internal functionality of the board.

Each of these boards has several different design areas in mind. For example, the Arty 1 and Arty 2 boards place a significant emphasis on power and ease of use out of the box. With both boards, all needed to get started is a micro cable and any composite cable. Ones that you might need for your project already soldered to the board itself.

Xilinx Spartan-7 FPGA Boards Features

The Arty boards are the first FPGA boards that have Digilent’s new Artix-7 FPGAs. Both boards use the same basic schematic. However, they differ in handling power and forgo onboard power supplies to ensure that the boards are small enough to be portable.

Configuration

Configuring the Xilinx Spartan-7 FPGA boards is relatively easy. However, it can be confusing for those who have little to no experience with programming FPGAs. In all reality, this process is not difficult, and it simply takes time to learn how everything works.

You first need to use Xilinx’s WebPACK tools to configure the Artix-7 FPGA on either of these boards. The JTAG debugger that you need to do this comes with the board when you buy it. These boards also come with two micro-USB cables so that you can plug them into your computer.

Each of these boards has a Pmod connector so that you can use Digilent’s Pmod peripherals with the board. The connectors are compatible with the older Pmods, so any Pmod peripheral will work without issue. SPI Flash drives or JTAG debugger cards are beneficial with these boards. This is because they allow you to store files on them for easy transfer to other devices instead of transferring files to an SD card.

Support The Digilent Pmod peripherals work great with both boards, but the documentation can be confusing. The “Getting Started” section in the user manual says nothing about using them. The Pmod peripheral pages often list features that do not exist (for example, there is no six-channel A/D). QSPI flash drives with the Arty boards work, but they do not support multi-bit reads and writing like the SuperCap and Spark boards do.

Memory

Because these boards only come with 8MB of onboard memory, you will need to add at least one additional memory chip if you wish to store data and programs on the board itself.

The memory on these boards can last for a while, and it is unlikely that you will run out of space while working on something. The documentation lists the memory as being dynamic, but this is inaccurate. More accurate information is that you can write the memory, but it will not disappear.

Processors

These boards have two different processors onboard. The first is a single-core processor known as the TriCore processor, which functions at 633MHz. It has 4kb of embedded DDR2 RAM and 8kB of embedded SRAM.

The second processor is the BM3358 dual-core processor, which functions at 400MHz with two MB of embedded DDR2 RAM and 16kb of embedded SRAM. It also has 4kb of EEPROM to store configuration data.

The two processors are different in terms of how they operate, but they both function well. You can use these processors independently or together to do different things at the same time.

We should use the TriCore processor for low-power applications. This is because it requires very little energy to run, and it will not consume much power. The BM3358 is better suited for high-power applications since it can consume more energy than its companion chip.

Control & I/O

The Arty 1 and Arty 2 boards have a single user I/O port, allowing an external to wire the switch to the board. This allows the board to work as a simple switch, and it is beneficial for projects that need more than one piece of equipment to work simultaneously.

The boards also have a single DIP switch, allowing five different serial ports to connect to the board. This will enable you to use the boards with a variety of software tools and peripherals.

Both boards have a standard JTAG port that can debug code or use the board as a programmer. The Artix-7 FPGA also has an embedded serial port, but neither of these two boards has this feature. User pushbuttons are available for them, but they are somewhat limited in what you can do with them.

Both boards have 16 digital I/O pins that we can use to send or receive data. They also have four analogs PWM channels that can process their inputs or output data. This makes both boards extremely useful for HMI applications. It is because you can use PWM channels to display any image, text, or anything else that you might need on the screen. DIP switches are available to control the digital I/O pins and run a simulation to determine what they do.

The Arty 1 and Arty 2 boards can work as a general-purpose development board that we can use for various projects. The TriCore processor on these boards will not carry heavy loads very well, but it will manage those loads without issue if you need it to run programs.

Expansion Connectors

The Digilent Artix-7 Spartan-7 FPGA boards come with a variety of expansion connectors. It allows users to connect the boards to their other hardware.

The first expansion connector these two boards have is a Pmod connector. It allows the connection of other Digilent peripherals to the board. We can use them with both boards, but they will not work with the XC7A200T FPGAs on the Spark Board or SuperCap. VITA 57.1 FMC LPC connector This FMC connector allows users to connect a VITA 57.1 programming board to the board. There is no documentation on the Internet for this device. So, it may be easy to use wrong or damage something during the process.

The Digilent Artix-7 Spartan-7 FPGA boards have an LPC connector. So, users can program their peripherals instead of using the Xilinx software tool. Pmod Headers This connector allows users to connect an external display with a separate power supply to the board.

This adapter will allow users to connect an external USB flash drive to the board. You must connect it in this format, or it will not work correctly. This connector tells the board what memory banks are available on the expansion header. The only free bank on this board is A0, so if you do not have one of these connectors, you will not connect your expansion device to the board.

Communication & Networking

These boards can connect to any other piece of equipment you might have, but they can also communicate with each other.

The Artix-7 FPGA on the Arty 1 and Arty 2 boards comes with several built-in Ethernet channels that connect Ethernet-capable peripherals.

Arc Risc is an architecture created by Digilent that allows users to connect different boards over Ethernet. The UART to USB Bridge allows any USB device to connect to the board using a universal serial bus. This will allow you to use a variety of peripherals with these boards, but it will not allow the boards to communicate with each other.

The XADC-4096 can also connect to the two boards via Ethernet, but it is essential in sensing data from a piece of equipment that is not an Arty board. The RJ-45 Tri-Speed Ethernet Connectors can connect other boards because they have an RJ-45 connector to plug the cable into. This is not a common feature for FPGAs, but it can be helpful in a variety of applications.

These two boards have two different ways of allowing the user to connect their board to other equipment. The first way is with a USB cable because it enables you to move data between your board and any other piece of equipment that has a USB port.

Display

The Arty boards have a DSI LCD connector that allows the user to connect a TFT LCD or a digital micro-mirror display. This connector drives the display directly and ensures nothing is wrong with the data it is receiving. The TriCore processor on these two boards will also be able to drive the same displays. However, it will not do so since it cannot change the contrast or other settings on these displays. The HDMI Video Output on these boards will allow you to connect your board to an HDMI-capable display.

The Artix-7 FPGA on the Arty boards also has two DSI connectors that will allow you to connect a digital micro-mirror display or TFT LCD. The only difference is that the user must provide their power to the device instead of a USB cable. Additionally, the MIPI-CSI Camera Interface connector available on the Arty 1 and Arty 2 will let you connect a camera to these boards. Also, we can use the MIPI-DSI Display Interface to connect any TFT LCD. The DSI connector on the Arty boards also has an HDMI connector so that you can connect your board to an HDMI-capable display.

The Ralink RT5350F Wifi USB adapter for these boards can connect your board to any other device with a wireless network connection. The only problem with this adapter is that it does not have an antenna. So, if you are using it for anything more than basic programming, you will need to figure out how to increase the range of your wireless network.

Clocking

These boards come with several different clock speeds available for users to use. These clocks allow you to adjust the speed at which the FPGA is working, but they must have an appropriate voltage to run from.

The Arty boards have a VHDL source used for all their I/O signals. It is also the same as the clock used during normal operation, so there is no need for a clock input on these boards. The board will automatically adjust to a stable clock speed depending on the voltage that it gets. You can adjust the clock speed that it runs at using either of these two controls. The Artix-7 FPGA on these boards creates an internal gyroscope that will adjust the clock speed depending on moving.

The Artix-7 FPGA on these boards has two different clock outputs that you can use with external oscillators to drive it at different speeds. The first is the WANCOOP1 output which we use with external oscillators. It has an I2C Programmable Clock input, creating any clock speed that the user would like. The second clock output is CWAN1, and we can also use it with external oscillators, but it cannot create any clock speeds.

Power

There are two different power inputs available for this board. The first is the USB connector that allows the user to supply it with either 3.3V or 5V of power. We can use it to charge a battery directly, but we cannot use it if an AC adapter has a bad connection to the board. We refer to the other power input on these boards as BATEN1, and it has a 6-pin connector that allows users to supply the board with 5V of AC power directly.

The Arty boards also use the same two types of power inputs, but they come with more combinations of power supplies that we can use. These boards come with a C10-C16 DC power input that will allow users to supply the board with any voltage between 10 and 16 VDC. There is also an AUXIN1 input that can supply the board with up to 3A of current.

Advantages of the Xilinx Spartan-7 FPGA Boards

The Spartan-7 FPGA on the Arty boards will bring a lot of advantages to any project you are working on. The integrated flash memory and USB connectors will allow you to load and transfer data between you and your computer at high-speed rates. The built-in power supply and clock generators will also help by eliminating the need for two additional parts. Still, there is no need to use built-in oscillators. This is because they cannot output as high of speeds as one can achieve using external oscillators. The wide array of Analog, Digital, I/O, and Interfaces make this board an ideal choice for almost any type of application.

The Xilinx Spartan-7 FPGA on these boards is the same as the one found on the Wonder Boards. It has many of the same features, but some additional features are not available on the Wonder Boards. The TriCore processor will drive more digital displays than a single TriCore processor can drive on a Wonder Board. The DSI connectors will be able to drive more displays, but the Artix-7 FPGA on these boards will not drive the same amount as a Wonder Board.

The Xilinx Spartan-7 FPGA on these boards also has two built-in oscillators that come at different speeds. So, their outputs will need amplification if you are planning to use them with an external oscillator. Working with top PCB companies such as RayMing PCB and Assembly will help you enjoy all the advantages stated above.

Limitations of the Xilinx Spartan-7 FPGA Boards

One of the most significant limitations these boards face is requiring an external oscillator to use with projects. The internal oscillators will not work since they are only allowed to output at slower speeds. This limits what types of projects we can do with these boards. If you plan to use them for applications where you need the fastest possible clock speeds, you should choose a board from one of the other series of boards from Xilinx. However, they all have more limited features than the Spartan-7 FPGA on these boards.

Another limitation that these boards have is that there are only two I/O connectors available. The Arty boards have a USB connector available, but they can only charge a battery connected directly to the board. We can use the Artix-7 FPGA on the Arty boards to charge a battery connected directly, but there is no option for an external power source. The only I/O connector available for the Arty boards is an Analog Input connector. However, you cannot use them to connect any digital signals made on the Artix-7 FPGA. This does not limit what types of projects we can do, but it will make using them for some applications more difficult.

The Spartan-7 FPGA on these boards does not come with built-in oscillators.

Conclusion

These boards are great supplements to any other board that you have for your project. You can use them to perform tasks that were once impossible because of the limitations of other FPGA boards. They do not offer as many features as the Arty family, but they still provide plenty of features to make them useful for almost any type of application. They are not as good as the Wonder Boards, but they are still high-quality FPGA boards.

If you know where to go on the Internet, you can find a USB board already configured for FTDI connection. First, you need to check if your computer has a USB port, as you can use any USB-powered device to communicate with your FTDI device. Second, you need to connect the FTDI board to your computer with a USB cable. Third, within the driver, go onto the “Communication” tab and check that “USB Serial,” “USB Device Class,” and “USB Version” are all set to the right values.

After this, it is time to start working with your FTDI device! FTDI devices have many options, so many are not ready by default. Just google around to find out which settings you need for your specific hardware.

Among the settings that you may need to adjust in your FTDI device, you can find:

1. Set the baud rate.

Check the documentation of your device to say what value it needs.

2. Setting serial port parameters.

The FTDI board sets these automatically. However, if you have one of those USB devices which works with some other protocol (such as CAN Bus) or if you want to use hardware flow control, then set these parameters manually.

What is an FTDI chip?

An FTDI chip is a small computer with one significant difference. Its pins connect to another electronic device instead of installing them into a circuit. Thus, we can use the FTDI chip to talk over an RS232 serial interface in any other electronic device.

There are many uses for an FTDI chip. For example, we can use it as a serial adapter to convert RS232 signals to USB so that you can use the host computer’s USB port with it. Or we can use it as a USB-to-RS232 converter to connect to a computer that does not have a built-in RS232 interface. Also, we can use it as a USB keyboard (hence its name).

Many of these applications were there before, with various results. But this time, I will describe how you could use your FTDI chip directly in your electronics project. I will assume that you are willing to do some soldering and have basic knowledge of electronics.

What are the advantages of using an FTDI chip?

Since the FTDI chip is a separate computer that we can buy for under $5, it is cheap to connect. In addition, because it uses its memory and processor while sharing a single interface with other devices, communication between the device and the FTDI chip is faster than communication between two computers using an RS232 cable.

Since there is no cable to connect, you can fit the device into much smaller spaces than if you had an RS-232 card. Generically, this means it will be easier for you to hide the chip from sight and deliberate observation by someone else.

The FTDI chip comes with drivers that should work without configuration on most Windows, Linux, and OSX machines. Hence, you can use it in a wide range of environments. There are even cases where you can plug an FTDI chip into your USB port, and it will work immediately. This is not always possible with RS232 cards that we need to configure for the operating system to recognize them.

It is very easy to connect almost any device to an FTDI chip. You need to read your hardware documentation, as there are usually no details about this specific feature.

Unlike an RS232 card that we may need to configure to work, the FTDI chip is always ready-to-use. There is no need for extra software or configuration. It will always work as soon as you plug it in.

One can send data, and you will never forget how to connect your device back and forth with an FTDI chip. You will never have to learn extra commands or settings for your hardware to work, but you can use any protocol you require.

Types

There are three main types of FTDI chips.

We also various manufacturers of these chips that include RayMing PCB and Assembly. But many use the same chipset and basic features.

FTDI Basic (V1.0)

The FTDI Basic (V1.0) is the oldest and the most basic of all the chips. It does not have any automatic reset, nor does it auto-disable for unused pins (“floating”). Also, it has a slight problem connecting to some USB ports at higher speeds.

We can find it in early FTDI cable products and most USB breakout boards.

FTDI Cable v2

There also exists an FTDI Cable v2. It has the same features as the FTDI Basic but uses two chips instead of one. It also has additional features such as automatic reset on power-up, auto-disable for unused pins, support of USB 2.0 speeds. There are some examples of this type in cables and USB breakout boards (for example, “FTDI Basic to USB Cable v2 – New”).

FTDI Basic v3

In 2009 there was a new type called the FTDI Basic v3.

The main difference is that it does not have the problem of connecting to a USB port that has a high-speed mode. Instead, it works only with a “fast” speed USB port, normally found on all modern computers. As a result, this is the only way to plug an FTDI Basic v3 cable into an “old” computer running Windows XP / Vista or Mac OS X and expect it to work.

The FTDI Basic v3 is available in most new cables and USB breakout boards.

FTDI cable v5

There is also an FTDI cable v5 which uses the same chipset as the FTDI Basic v3 but adds a new feature: auto-disable for unused pins.

It’s also now available in most new cables and USB breakout boards.

The difference between the FTDI Basic v3, the cable v5, and the original FTDI Basic is that they use entirely different chipsets (they do not share features).

FTDI Basic v3 and FTDI cable v5 share the same features, but the FTDI Basic v3 has 1.1V levels, while the FTDI cable v5 has 3.3V levels.

The original FTDI Basic is in level 0 (0V).

Note: If you want to buy one of these chips, please note that many fake versions are available on eBay and other sites. Please check with your seller for details of their guarantee and warranty.

The FTDI Cable v6

FTDI Cable v6 came in 2010 to replace the FTDI cable v5.

The main difference is that it has a higher voltage level (3.3V instead of 1.1V) and thus a greater distance for the current to flow without damage to the chip.

Also, it comes with improved software from cable v5. It has a new and easier method to configure your device using its application software and standard USB hub software.

The FTDI cable v6 is available in most new cables and USB breakout boards.

Pin Configuration

The most common example is when you want to connect your Arduino board to the FTDI cable:

GND pin is the ground (commonly known as “-” or, on an Arduino board, some of the GND connections). The TXB pin is for sending data from the FTDI chip to your Arduino board. We need to connect this with the RXB pin on your Arduino.

The RXB pin is for receiving data from the Arduino board. So we need to connect this with the TXB pin on your Arduino.

Other devices may have different pinouts. However, they should be compatible as long as they fit into the same connections.

Newer FTDI chips are 5V tolerant, meaning they will not damage the Arduino board if abused by connecting it to a higher voltage. Still, other devices connected via an FTDI cable may suffer damage because they may not be 5V tolerant.

Downloading and installing the drivers

This can be very tedious since you need to download the correct driver for your operating system. You need to find the correct driver by following some steps:

1. Download and install the free software “FTDI Driver Tool” from here
2. Select “USB to Serial Adapter” from the devices menu in the FTDI driver tool.
3. For Windows, click on the “Start” button and type “devmgmt.msc” into the search box on top of the window. Then press [Ctrl+E] and follow the steps to select “FTDI Device” from the device manager.
4. For Linux, open a terminal window and type “lsusb” into the search box on top of the window to find the correct driver. Also, you can do a google search for “Linux USB serial adapter.”
5. For Mac OSX, open a terminal window and type “ls -l /dev/cu.*” into the search box on top of the window to find the correct driver.

How to use FTDI USB to Serial Converter?

When you connect cable v5 to a computer, it will automatically reset and install its software on the computer.

You will then get an application called “FTDI Basic Control,” where you can configure your device.

One can also use the standard USB hub software supplied with most operating systems (for example, “WinUSB” in Windows 7). It helps to configure your device from another computer or control it from another application.

There is no need for any special tools to configure your device.

How to install the FTDI Basic Control software

To install this software, you will need to get the “Win32 Disk Imager” program from here and install it on your computer.

The program will then automatically install the FTDI Basic Control software.

Advanced configuration of the FTDI Basic Control software

The Advanced Configuration is only needed if you want to read or write directly to your computer’s serial COM port without using a virtual COM port. For example, to add advanced functionality to your project.

You will also need the “CMDebug” software from here.

It will show you detailed information about all the pins on both your FTDI USB-Serial Converter and your computer’s serial port.

The COM port and FIFO information are also displayed. It helps you use the standard “CMDebug” software to write to your computer’s serial port if you need to.

You may need to use this advanced configuration in rare circumstances. For example, if you want the complete I/O pins of the FTDI USB-Serial Converter to be available for your use.

FTDI Driver Installation

The FTDI driver installation will depend on your operating system.

In general, if you install the FTDI Basic Control software (the “FTDI USB-Serial Converter” control panel), then you should install the drivers automatically when you connect the cable v5 (OE/DO) to a computer.

Otherwise, you will need to install the drivers manually.

The FTDI Basic v3 is now obsolete. There are very few sellers of this chip in a new condition available on eBay and other sites. Check with your seller for details of their guarantee and warranty. FTDI has discontinued selling the FTDI Basic v2.

As of 2015 (and preceding years), there are very few sellers of this chip in a new condition available on eBay and other sites. Check with your seller for details of their guarantee and warranty.

The FTDI cable v5 chips are compatible with the FTDI Basic v2 and v3 cables.

However, the FTDI Basic v2 and v3 cables will not work properly with cable v5.

The general recommendation is to use the most up-to-date cable available for your system. You can use either the FTDI Cable V6 or a USB breakout board from Adafruit Industries.

It will provide better compatibility and more advanced features in most cases.

This chip has four wires. It is a popular chip, and many maker kits are available in new condition.

The FTDI Basic v4 is not compatible with cable v5 (OE/DO). It will only work with a cable v6 (OE/DI).

How to use FTDI chip in Linux

The FTDI USB-Serial Converter is a virtual com port device.

We can use it in Linux as a serial port device by accessing it through the /dev/ttyXX interface (where XX is “d,” “i,” “u,” or “g”).

One must set device permissions to mode 0666 before the Com port works (otherwise, the device will not be visible to the kernel).

Where d corresponds to 1.1V, I correspond to 3.3V, u corresponds to do 12V, and g corresponds to 5V (1.2V) (OE/DI mode only).

Check the output of lsusb for a line beginning with “bcdDevice” to determine the current mode.

The modes are set by inserting the OE/DI wire into a connection on the FTDI USB-Serial Converter and pressing the button on the converter.

For example:~$ echo 3 > /dev/ttyUSB0_0 sets it to Com port mode 3 (3.3V).

The user running udevadm can also change the USB.usermap files as a root user.

As of 2010, the “firmware” wheels available from FTDI only include drivers for Microsoft Windows (32/64-bit).

Compatible drivers for Linux exist in the kernel and are part of many distributions.

These drivers do not have the recent updates and are missing support for the latest chips.

Unfortunately, the current version does not support the newer chips.

Conclusion

The FTDI Basic is the most varied of all the chips. However, we can modify it (for example, by adding a “floating” pin), and it works with practically any USB device.

Have you been searching for low-cost humidity and temperature sensors? Great timing! Here, we will discuss the DHT11 and DHT22. These are the two well-known humidity and temperature modules for Raspberry Pi and Arduino.

Though DHT11 and DHT22 are slower compared to some temperature sensors, both boast of benefits that include great long-term stability and low consumption of power. In addition, you can get relatively high accuracy in measurement at an affordable rate.

Both DHT sensors are great for any home project such as weather stations, inspection and testing of equipment, garden or farm monitoring systems, environmental control systems, and more.

DHT sensors are composed of two major parts. These include a thermistor having a basic chip and a humidity sensor. Both are responsible for converting from analog to digital.

What is DHT11?

DHT11 can be referred to as a basic, low-cost humidity and temperature sensor. It has the capability to detect relative humidity and temperature. The relative humidity here refers to the quantity of air’s water vapor compared to the water vapor’s saturation point in air.

Furthermore, DHT11 is widely regarded as the humidity and temperature module for Raspberry Pi and Arduino. Therefore, due to its many benefits, hardware enthusiasts favor the DHT11. Also the DHT11 humidity temperature sensor also works with respect to the new DHT11 module.

 Features

• Consumes low power and has a great long-term stability
• You can obtain a relatively high accuracy in measurements at a low and affordable cost
• Range of humidity falls between 5 – 95% RH, and having a ±5%. Also, the range of temperature falls within -20 – 60℃ and having a ±2%.

Comparing the old and new DHT11, we can see some differences. The old DHT11 is called ADSONG, while the new is ASAIR.

• The old DHT11 has a resistive sensor, while the new DHT11 has a capacitive sensor
• Old DHT11 has a humidity range falling between 20 and 95%, while the new DHT11 has a humidity range that falls between 5 and 95%
• The old DHT11 has a temperature range falling between 0 and 50℃, while the new DHT11 has a temperature range that falls between 20 and 60℃.
• The old DHT11 has a temperature resolution of 1℃, while the new DHT11 has a temperature resolution of 0.1℃.

From this comparison, you can clearly see that the new DHT11 has a wider range for both humidity and temperature. Furthermore, its temperature resolution is also lower.

What is DHT22?

DHT22 is also referred to as RHT03 or AM2302. The DHT22 features a temperature sensor with high precision, as well as a humidity sensor. It makes use of a digital module acquisition technology, as well as humidity and temperature sensing technology. This is just to ensure that it is highly reliable and has great long-term stability.

Furthermore, DHT22 features a sensing element, as well as a measuring element of temperature of high precision, which is connected to an 8-bit microcontroller of high performance. Therefore, it has great quality benefits, very quick response, high-cost performance, and high anti-interference ability.

Features of the DHT22

• Its size is ultra small
• Power consumption is extremely low, coupled with a distance of signal transmission of over 20 meters. Therefore, it can withstand applications that are most demanding.
• Range of the humidity sensor falls between 0 – 99.9% RH, and has an accuracy of ±2%. Also, the range of temperature falls within -40 – 80℃ and has an accuracy of ±0.5℃.

Note that the sensor module can be sold individually. Also, connection with 3 leads is easy. If you wish to connect the sensor using a longer wire, all you need to do is include a pull-up resistor.

What are the Differences: DHT11 vs DHT22

Temperature range: With respect to the temperature range, for DHT11, it falls within -20 – 60℃, while for DHT22, it falls within -40 – 80℃.

Temperature accuracy: DHT11 has a temperature accuracy of ±2%, while that of DHT22 is ±0.5℃

Humidity Range: the humidity range for DHT11 falls between 5 – 95% RH, while that of DHT22 falls within 0 – 100%RH.

Humidity Accuracy: DHT11 has a humidity accuracy of ±5%, in contrast to DHT22, which is ±2%.

Cost: The cost of DHT11 is $5.90 compared to that of DHT22, which is $9.90.

In conclusion, in all aspects, the DHT22 beats the DHT11. This includes humidity accuracy, humidity range temperature accuracy, and temperature range. DHT22 has just one downside, which is its higher price compared to that of DHT11. However, this is necessary, since you have to pay more to get the better deal.

Therefore, if you are searching for a sensor having a wider accuracy and range, then you should choose the DHT22. However, if you decide to choose the DHT11, no problem; it will also work well for your different projects.

Generally, both DHT sensors are regarded as slow and basic humidity and temperature sensors, which are great for hobbyists and beginners seeking to do some data logging. Both utilize one digital pin and function very slowly. You cannot query both sensors more than once for each second.

How do DHT11 and DHT22 sensors Interface and Work with Arduino?

Before we go into details on how DHT11 and DHT22 sensors interface and work with Arduino, let’s first consider how the two sensors work.

Working Principle of the DHT11 and DHT22

Here, we will be considering how the DHT11 and DHT22 sensors work. They are made up of a thermistor or temperature sensor, a component for humidity sensing, and an integrated circuit on the sensor’s back side.

For the measurement of humidity both sensors make use of a sensing component having two electrodes with a substrate for holding moisture between them. As changes in humidity happen, the substrate’s conductivity changes, or changes happen in the resistance found in between the electrodes. The IC measures and processes the resistance change. By doing so, it prepares it for reading by the microcontroller.

Measuring the temperature, on the other hand, both sensors utilize a thermistor or a NTC temperature sensor. A thermistor can b e referred to as a resistor that changes the resistance value with temperature change. The manufacturing of these sensors came to be by sintering semi-conductive materials like polymers and ceramics, so as to offer larger resistance changes with just little temperature changes.

NTC refers to the “Negative Temperature Coefficient.” This means that there is a decrease in resistance with every temperature increase.

Circuit Schematics

Sensors DHT11 and DHT22 feature four pins – data pin, VCC, an unconnected pin, and GND, with all four having no usage. There’s a need for a pull up resistor from 5-10 ohms to ensure the data line is kept high to ensure that there is a communication between the Arduino board and the sensor. Some of these sensor’s versions feature breakout boards having an in-built pull-up resistor having only 3 pins.

Both sensors feature their personal single wire protocol. These are used in data transfer. This protocol also requires accurate timing. Also, you will find the diagrams required for getting this data from both sensors on their datasheets. However, there’s no need to be concerned about the timing diagrams. This is because the DHT library will be useful here as it handles everything.

Pinout of the DHT11 and the DHT22

It is fairly easy to connect both sensors – DHT11 and DHT22. As mentioned earlier, they feature four pins.

VCC pin: This pin provides the sensor’s power. Although the voltage supply falls between 3.3V – 5.5V, it is recommended to work with the 5V supply.

As regards the power supply of 5V, the sensor can be kept for about 20 meters. In contrast, for the supply voltage of 3V, the length of the cable cannot be more than a meter. If this happens, the line voltage will drop, thereby causing measurement errors.

Data Pin: The data pin is the medium through which the microcontroller and the sensor communicates

NC: This means not connected

GND: This pin has to be connected to Arduino’s ground.

Connecting the DHT11 and DHT22 to the Arduino UNO

By now, you should have a good understanding of the way DHT sensors function. Now, we can start connecting it to the Arduino.

Fortunately, it is not important to connect both sensors – DHT11 and DHT22 – to Arduino. Their pitch pins of 0.1 inches are fairly long; therefore plugging them into breadboards will come in. Using the 5V, power up the sensor and then connect them ground to ground. Lastly, connect the digital pin #2 to the data pin.

Also, you need to place a resistor (pull-up) of 10KΩ between the data line and the VCC to ensure it is kept HIGH. This makes proper communication between the MCU and the sensor. However, if you possess the sensor’s breakout board, then there’s no need to include an external pull-up. Also, it features a pull-up in-built resistor.

After achieving this, you can now go ahead with uploading some code and get it to work.

Printing of Values on the Serial Monitor

Both sensors, DHT11 and DHT22 feature their personal single wire protocol, which are utilized for data transfer. There’s a need for precise timing for this protocol. Fortunately, you don’t have to be bothered about this. This is because everything will be taken care of by the DHT library.

First download the library here, and then install it. To do the installation, open your Arduino IDE – Sketch – Include Library – Add .ZIP Library, then lastly, select the file that you have just downloaded. However, if you need more information on how to install the library, you can use this tutorial.

After installing the library, copy the sketch into your Arduino IDE. This test sketch helps in printing the values of the relative humidity and temperature on your serial monitor. Let’s explain this sketch in detail.

After uploading the sketch, you will see a window that reveals the output delivered by Arduino.

Explanation of the Code

The sketch begins by the inclusion of the DHT library. Then, we have to define the pin number of the Arduino to which the data pin of our sensor is connected; we then use it in creating a DHT object. By doing so, we will be able to access any special function that relates to the library. This is shown below:

• #include <dht.h>
• #define dataPin 8 // Defines pin number to which the sensor is connected
• dht DHT; // Creats a DHT object

For the ‘setup’ function, there’s a need to initiate serial communication, because this serial monitor will be useful in printing the results. This is shown below:

• void setup() {
•      Serial.begin(9600);

For the ‘loop’, we will be utilizing the function read22(). This reads the DHT22 data. It takes the data pin number of the sensor as one parameter. You can make use of the read11() function if you’re tinkering using DHT11. This can be achieved by uncommenting the second line like this:

• //Uncomment whatever type you’re using!
• int readData = DHT.read22(dataPin); // DHT22/AM2302
• //int readData = DHT.read11(dataPin); // DHT11

As soon as you have the values for the temperature and humidity calculated, you can easily access them this way:

• float t = DHT.temperature; // Gets the values of the temperature
• float h = DHT.humidity; // Gets the values of the humidity

Now, the DHT object returns the value of the temperature in degrees Celsius. You can convert it to degrees Fahrenheit using this:

• //print the temperature in Fahrenheit
• Serial.print((t * 9.0) / 5.0 + 32.0);

Conclusion

Concerning precision, that of DHT11 is lesser than that of DHT22. It functions in a much smaller range of humidity and temperature. Asides from this, it is a bit slower, price point is lower, and its form factor is smaller too. If you desire some accuracy for your project, and you are okay with its higher price, then you should choose the DHT22. However, if this is not the case the DHT11 works fine. You can decide to work with any of the two.

This makes them more affordable for many different applications or situations. It makes them more popular for people who would like to get started using FPGAs without spending too much money.

These boards are generally essential for prototyping new ideas. It means that you will likely get your money back if you do not use your design after creating it. This makes it a reasonable investment, as you will have a product that you can sell or use later if you want to.

Versatile

The Xilinx Kintex-7 FPGA boards are versatile in what they can do compared to other boards. Since they run different processes instead of digital ones, they are more versatile when used with other components or protocols. Since there are so many kinds of applications that they can use, the users of these boards can use them in most situations without worrying about finding another application for them later in life.

Saving time

We can use the Xilinx Kintex-7 FPGA boards to save time in several different situations. Since they can run digital processes and other algorithms in parallel, they can do more work in less time than other boards. Since their processors are much faster than most other boards, they can handle more tasks during any period they spend running. This allows them to spend less time working on the design and more time on the actual procedure, making it easier for many different applications.

Optimized for quickly prototyping high-performance serial transceiver applications using Kintex-7 FPGAs

We use the Kintex-7 FPGA boards mainly to prototype high-performance serial transceiver applications. This means that we can use these boards for many different uses, but they are the most popular for this application. The reason for this is that there are very few boards like these on the market today. It makes them much more versatile if you need a board capable of doing a lot of work. If you need a board with a lot of memory or logic, this may not be the best option for you. If you only need a small amount of memory and have very little to no design capabilities. It may be the best choice for you as it will allow your design to run faster and save you time in the long run.

Advanced memory interface

The Xilinx Kintex-7 FPGA boards have a memory interface to install more memory than might be commonly installed. This means that they can store more information in different parts of their system. It makes it possible for you to have stored data or files from another project stored on your board so that you can use the two together later. You can connect the memory interface to the Zynq-7020 MicroController present in these boards. It makes it easier for all your information to be easy to access and easier for the two systems to communicate with each other.

Modular Xilinx MicroBlaze softcore

The Xilinx MicroBlaze processor is a modular component of the board, which means that we can replace it with another processor that a different company makes. This means that you will not be stuck with the MicroBlaze processor if you would instead use a completely different one. Since you can change most of the components on this board, it is easier for you to do most things with your board instead of only using one specific component or type of component.

Ultra-low power consumption

The Xilinx Kintex-7 FPGA boards can consume less power than most other boards on the market today. This is because they can transition between different power-saving modes that allow them to be more energy-efficient. Since they use less energy, we can use them in different situations without worrying about running out of energy. This also increases their versatility as you will not have to worry about keeping your board running if you cannot have it always plugged into a wall socket. The Xilinx PicoBlaze processors used in these boards are also much slower than other processors. It also means that your board will be able to run for a longer period without having to worry about it running out of energy.

This means that if you need a board with a lot of memory and logic, this may not be the best choice for you. If you only need a small amount of memory and have very little to no design capabilities, this may be the best choice for you as it will allow your design to run faster and save you time in the long run. These boards also only contain one MicroBlaze softcore processor, which means that you will only be able to use one simultaneously instead of having multiple ones running at once.

Another limitation is the fact that we cannot use the Xilinx Kintex-7 FPGA boards in every situation. This means that if you need a board that can do more than just running serial transceivers, this may not be the best choice for you. If you only need a board for serial transceiver applications, these boards can do all of them in very little time, saving you energy and time in the long run. Since these boards are suitable for serial transceivers, they contain only one MicroBlaze processor instead of multiple ones, making them harder to use in other situations.

We can use the Xilinx Kintex-7 FPGA boards in many different electronics applications but cannot do everything other boards on the market. They can run all of the software required for serial transceiver-based designs but will need to rework them or change to run any other program. Since these boards contain only one MicroBlaze processor, we cannot use them in any project that requires multiple processors working at once.

The international electronic manufacturing industry is an enormous industry worth over $200 billion. The industry has grown at a rate of 25% annually for the last decade and shows no signs of stopping. With such rapid growth in just a few years, it’s not hard to see how quickly the electronic manufacturing market evolves. It changes in response to innovations and technological advances in development. Such is especially true in the FPGA market.

Xilinx is one of the largest FPGA manufacturers in the world, with more than 400 employees worldwide. Xilinx has been an industry leader in FPGAs since their inception with their first FPGA, the XL-3. Since then, they have continued innovating and developing new technologies. They help companies design their next-generation products with high-speed processing power and low power consumption.

The last couple of years have seen Xilinx releasing new FPGA products and various new boards for different markets led by Chinese firm RayMing PCB and Assembly. These boards help improve the industry’s ability to operate efficiently and securely behind closed doors, leading to safer, faster, more reliable products. Being able to use these boards and the FPGA devices themselves will vastly increase the value of the product design. Unfortunately, most products still end up being custom-built because of product, process, or materials constraints.

Difference between Xilinx and Altera

Xilinx & Altera are both FPGA manufacturers, but they are very different in architecture, FPGA families, and, most importantly, price.

Xilinx (NASDAQ: XLNX) is an American publicly held semiconductor company founded in 1984. Altera (NASDAQ: ALTR) is an owned Denver-based manufacturer of programmable logic devices for FPGAs. Altera is the only semiconductor company to be part of the NASDAQ since its inception.

Xilinx has been manufacturing FPGAs for 25 years. Altera has been manufacturing programmable logic devices for 22 years.

Xilinx has been designing and selling FPGAs for 25 years. In those 25 years, they have become the focal point for high-performance FPGA products used in all major industry sectors. It includes communications, aerospace/defense, medical devices, industrial control systems, and many more.

Altera has been designing and selling programmable logic devices for 22 years. They have done so through their partnership with Intel, which they entered in 1991. The first FPGA product that Altera manufactured for Intel was the “IUS.” Likewise, Altera’s first programmable logic device was the EPM3000, which came out in 1994.

Xilinx manufactures programmable logic devices (FPGA). These devices consist of programming blocks that we can configure to different configurations using a computerized design tool. Once the design is ready, we can end it with a manufacturing process such as an automated router or panel fabrication. We can make FPGAs with regular size integrated circuits (IC) and regular electrical components. The advantage of using regular ICs and electrical components is that they can build large and complex designs.

Xilinx utilizes a network (known as the Zynq system) to make programming faster and easier.

What is Xilinx Spartan 3 FPGA?

The Xilinx Spartan-3 FPGA is an integrated circuit that we can use for a variety of purposes. The Spartan-3 FPGA consists of an Accel-FPGA device. It contains programmable logic and embedded memory. The Virtex-E FPGA has hardwired logic cores and memory blocks. We bring these two devices together by a PLD (programmable logic device) controller unit.

Getting the most out of this powerful combination is possible by Xilinx with its new vision for embedded FPGAs. The main elements of the framework are:

Xilinx continues to expand its embedded FPGA portfolio with tools that allow software development in C/C++, including a free environment for development. The tools are available when used with Xilinx’s programmable logic development boards, called Embedded Development Boards.

The Spartan-3 FPGA hardware components

Accel-FPGA device

This device contains programmable specific logic, embedded memory, and an input/output port. So, the programmable-specific logic allows for the customization of the device we use in various applications. The embedded memory does not hold any information about its contents or location. Instead, we control the hardware attributes through commands sent to the device using the Accel-FPGA interface.

Xilinx Virtex-E FPGA

This device’s design is specifically for use with the Accel-FPGA. It contains hardwired logic, embedded memory blocks, and an input/output port. The logic implemented in the device provides maximum bandwidth and performance to external circuitry on the board. The hardwired logic on the Virtex-E FPGA limits flexibility of the board. However, it provides faster performance than that of programmable logic on the Accel-FPGA. We control some of the hardware attributes through programmable logic on the Accel-FPGA. Also, we control them through commands sent to the Virtex-E FPGA using the Virtex-E interface.

In addition to the above hardware components, we refer to the board design software for this board as Code Composer Studio. This software is a tool that allows a registered Xilinx developer to create FPGA designs and modify them through a graphical interface, much like that of a software development kit (SDK). The software also allows the user to build the design into a bit file and download it to the FPGA board. Code Composer Studio uses the ISE for programming and debugging purposes.

Xilinx also makes available a free development environment for this FPGA board. The software, which we call the Xilinx Device Development System, provides a C/C++ programming environment for writing FPGA designs. It also allows the user to compile the design into a bit file downloaded to the board. The XDS is available for download at Xilinx’s website.

The Spartan-3 FPGA Software components

Several software elements are essential for product designers who want to use this particular FPGA board. The software components are:
1. Xilinx Cell-based Platform Development Kit (CP2K). This software tool allows the user to create C/C++ programs compiled into bit files that we can then program into a Xilinx FPGA device.

2. Xilinx ISE (Integrated Software Environment). Code Composer Studio includes this software and allows users to control the hardware through a graphical interface. It also allows the user to develop software for use with this board.

3. XILINX Virtex-E Programmer – This software allows the user to compile C/C++ code into bit files transferred to the Virtex-E FPGA.

4. Xilinx ISE Programming Model (IPM). This software tool is essential in programming the Spartan-3 FPGA board through Code Composer Studio.

5. Xilinx Embedded Development Board Emulator. This software allows users to run their programs on the FPGA board using an integrated MIPS processor. Again, we do the bug fixes through an Eclipse-based C/C++ development environment.

In addition to the software components listed above, additional we use software tools for simulation purposes. These tools include:

6. ModelSim HDL Simulator – Mentor Graphics initially invented a simulation tool, but Xilinx acquired it in 2001. It performs detailed simulations of the design during its development and debugging.

7. VCS (Verification and Constraints Shaping) – This tool speeds up the constraints debugging process.

8. CLPR (Code-Level Place and Route). This tool performs full-chip routing after thoroughly testing and debugging the design. We may need to use it after making changes to the design due to testing and bug fixing errors.

Features of Spartan 3 family

The Spartan-3 family supports the following features:

1. I/O Capabilities

The Spartan-3 FPGA has an expansion port plugs in one or more boards to plug into the expansion bus. The board connected to the expansion bus can include a processor, memory, and other peripherals. Together, the FPGA and board connected to the expansion bus can create a sizeable embedded system.

2. Logic Capabilities

The programmable logic of the FPGA contains resources such as memory blocks, DSP slices, and mega-flops. A mega-flop is a unit of logic that executes one million floating-point operations per second. We can use logic resources in FPGAs with multiple different combinations to fulfill different design needs.

3. Reduced pin count

We integrate the Spartan-3 family with many minimally-sized resources that reduce the pin counts on the design. For example, Xilinx has combined the DSP slices, memory blocks, resources for mega-flops with the programmable logic resources. The Spartan-3 family provides a 28 nm DSP block to implement highly efficient DSP algorithms.

4. Memory

The Spartan-3 family supports a RAM module that we can use to store a random access memory (RAM) block from Xilinx’s Offcore Memory Library. We place the RAM block between the processor and SRAM blocks of the computation region of the FPGA device. As a result, we configure the RAM block as a memory block that provides an additional storage area and additional random access memory to the components of the embedded system.

5. Low power consumption

The Spartan-3 family consumes less power than other FPGA families. For example, the device consumes less than 1 W of power when executing a 1 MHz operating point (BOD level). With heavy use, such as during simulation, the device still requires less than 0.5 W of power.

6. High Throughput and Large Capacity Memory Blocks

The Spartan-3 family supports a large RAM block that can store data, such as 1 GB of data, for storing large amounts of data during FPGA simulation. We can detach the RAM block from the main computation region to access and debug the memory block easily. We can configure the relative size of the RAM block using a configuration block at index 8 in the configuration file.

7. Optimized Logic Design

The logic of the Spartan-3 family has an optimization using Xilinx’s tools. This reduces the amount of logic needed to perform a specific task.

8. Fast Boot-Time

The Spartan-3 family has a fast boot time because it has an internal configuration memory loaded by the circuit board at the start-up. This speeds up the configurations process to allow users to start using their designs quickly.

9. Reduction of Existing Design Iterations

The Spartan-3 family can reduce existing design iterations due to design predictability. This happens because the device uses FPGA functionality rather than general-purpose logic elements. Reducing the number of iterations required to implement new designs reduces the time needed to re-design a design.

10. Support for a Variety of Applications

The Spartan-3 family supports various applications from low-frequency communication blocks. For instance, those used in modems to high-performance communication blocks in radios and communication equipment. In addition, the devices support low-frequency control functions. For example, those used in central processing units (CPUs), digital signal processing (DSP), high-frequency fixed-point DSPs, and floating-point DSPs.

Advantages of the Xilinx Spartan-3 FPGA Boards

The following are some of the areas of application for the Spartan-3 FPGA boards:

Conclusion

The Xilinx Artix-7 FPGA board is ideal for use in different application scenarios suited to the device’s functionality. However, this does not mean users will be able to use it for all situations. Users must stay informed about the capabilities of the device to ensure they do not exceed the 1,000 Mbit/s bandwidth limit, which will leave them with fewer options for expanding their computing resources.

Mice are pretty small. Whenever they bite on anything, they leave some tiny marks behind as evidence. On your printed circuit board, you may find some “mouse bites”. Now, don’t get scared. These mouse bites don’t indicate rodent infestation.

Rather, these tiny holes assist in breaking out a circuit board from the manufacturing panel. Now, the locations of these holes are precise and dimensioned. Of course, they are similar to those nibbling you may find left behind by a mouse.

So, there’s no need to get your traps and cheese ready because our topic linking “mouse bites” to printed circuit boards has nothing to do with real mice. Rather, we will focus on mouse bites PCB and its dimensions to ensure you comprehend the manufacturing or circuit boards better.

What are Mouse Bites in PCBs?

 Mouse bites in printed circuit boards are sections of the manufacturing panel that helps in assembling and fabricating circuit boards. Some individuals utilize the “mouse bite” term to describe and explain the over-etching of copper. However, what we mean here is different.

PCB manufacturers lay out circuit boards in a panel making use of CAM – Computer Aided Manufacturing systems. This panel ensures that the assembler and fabricator is given additional board material for any handling during all processes involved in manufacturing, which is very critical for the smaller boards.

Normally, panels have a uniform size, and you can lay out multiple instances of your printed circuit board design within the panel’s outline. The panel will not just make board manufacturing easier. It also allows the processing or multiple boards in panels for a similar cost as one board.

Once the fabrication, as well as assembly processes of these circuit boards, has been completed, then you must separate them from their panels. The process of separating them is known as depanelization. You can achieve the depanelization process either by breaking out the boards along the “V-grooves” or pre-scored lines, or cut them out.

The boards you have to break out have to be routed already around its outlines. This will help in bringing a separation between them and the panel, which are held by just small material tabs. The removal of the “breakout tabs” takes place, thereby making the board free from the manufacturing panel.

These tabs also feature small holes, which ensure the easy breaking of the PCB, and reduce the stress of the boards. With each of the tabs broken along the holes’ lines, the material remaining will have the appearance of a “mouse bite” until you have smoothed it out.

Mouse Bite PCB: Locations, Dimensions and Sizes

The holes utilized for breakout tabs may vary. However, majority of manufacturers utilize five holes in breakout tabs having these dimensions.

The hole size is usually 0.5 mm or 0.020 inch in diameter. Concerning the spacing, they are 0.76 mm or 0.030 inches apart.

The spacings and sizes of the mouse bite PCB holes appear random. This reduces the cleanup needed after the breaking out of the board from the panel. Though, it takes less effort for a smaller hole to smoothen out, it will also need more holes to be drilled and leave out much bulk material.

However, if there are too big holes, the board will end up having mouse bites that are larger and will need smoothening out. The hole placement within this breakout tab is important as well. The goal here is drilling them nearer to the PCB edge. This helps in reducing the tab material leftover that needs to be removed.

Constraints to consider during placement of breakaway Tab PCBs

There are some constraints to consider while performing the breakout tabs’ placement around the outline of the board.

• Don’t make use of many tabs in order to save wear, effort, and time on its router bits.
• Have enough tabs that can support the PCB board fully in its panel throughout the operations of PCB assembly.
• Tabs having a minimum clearance of 0.125 inches should be located to the closest components.
• Don’t place the tabs close to circuitry or sensitive components areas. This could cause the board to experience more breakout stresses.

At times, stress damages coming to the circuitry or components due to the tabs breaking may not be seen till later. It may also cause intermittent issues that won’t be debugged easily. This is why the location of breakout tabs, a distance away from any sensitive area, is very important to the circuit board’s success.

Also, if you don’t use enough tabs, and you don’t place them strategically to support your board during the manufacturing process, your board may end up flexing too much. This will prevent a reliable assembly. Now, this is the point where the experience and knowledge of your PCB manufacturer comes in.

What is V Groove PCB?

The V groove PCB results after the splitting of circuit boards. This requires the cutting of the circuit board, and leaving a little material to help hold these boards. The final stages involved in the production is profiling the v groove pcb and cutting them from the manufacturing panel. This is either done by routing or v-cut scoring. There are some rules to adhere to when manufacturing V Groove PCB.

Rules When Manufacturing V Groove PCB

• Ensure that the board’s spacing is 0mm
• The spacing found between the outline and V-scoring line stays at 0.35mm
• The line for V-scoring has to be straight. Also, it must be a horizontal and vertical line.
• The minimum size of the v groove PCB should be 75 x 75 mm, while the maximum size of the v groove PCB should be 450 x 1245 mm.

Breakaway Tab PCB: Panelization Methods

There are multiple methods for Panelization of breakaway tab pcbs. Each of these comes with their own benefits and drawbacks. The board’s design present on the panel, as well as the panel, usually plays a big role in whatever method of Panelization will suit the application best. Let’s consider these factors.

Components: The importance of the component utilized on the board is just the same as its placement. Connectors and components that are sensitive may play a huge role in the most effective Panelization and breakout method.

Design: The board’s design plays the most significant role when determining the best method for Panelization. The clearance amount between the board’s edge and the components may make some of the methods less appropriate compared to the others.

Materials: Materials utilized in mouse bites PCB may end up limiting the Panelization method type that is best. This is because some of the materials can splinter easily during the breakaway process. Another factor is the thickness of the board. Particularly, all thin boards have a higher chance of breaking while assembly is on. Thick boards on the other hand, may give more problems during this breaking out as well.

These factors explained above limit the available choices to any given application. Many companies handling the assembly may combine different methods on a specific project. This is to ensure the array’s structural integrity coupled with mitigating the issues encountered while the breakout was on.

PCB Breakaway: Panelization Techniques

For breakaway tab pcbs, there are three techniques for Panelization. However, most of the time, just two are practiced.

Tab Routing Panelization

Here, mouse bites pcbs are usually pre-cut from the arrays and then held properly on the board. Most times, about 3-5 holes are utilized in the perforation patterns. With this method, you are sure to get some benefits due to its design support ability. You can also break them with your hands rather than using tools.

V Groove Panelization 

This technique for Panelization is very common. This uses V-shaped grooves in separating individual printed circuit boards. About 33% of the thickness of the board is removed by these grooves from the bottom and top of the board using a blade.

Most times, a machine is used in finishing the PCB breakaway process. This it does considering that the third left of the bard in-between your grooves is strong and stress can be put on the mouse bites pcb as well as its surrounding components through hand-breaking.

Solid Tab Panelization

You can design arrays using solid tabs between the boards, thereby improving the strength overall. However, the method for depaneling this panel type needs either a laser-cutting machine, a depaneling router, or a blade tool (hook-shaped).

The laser-cutter is very expensive. Also, they usually don’t work on boards that are more than 1mm thick. The router can cause vibration and dust. The blade tool with a hook shape is a less expensive option. However, they usually experience blade rotation, and are inefficient. Compared to the first two methods, this method is less common.

For majority of applications, the preferred method of panelization is Tab Routing and V-Score. One good thing that a PCB designer must understand is which of both methods works best for the application. Now the next step is designing their array to ensure breakout success and maximal strength.

Many people prefer using the V-groove method due to its surface stress reduction and efficiency. This array’s depaneling machines are also cost-efficient and relatively inexpensive. Better still, they require less maintenance, and they are portable. Though this method usually results in board edges that are rougher, this concern is rare for applications utilizing V-groove panelization.

Tab Routing Vs V Groove PCB Panels

Making a choice if you should use tab routing or v groove methods in the panel largely depends on your PCB design. These are some factors to consider before you make a decision.

Edge components

It is possible that your breakaway tab PCB relies on components attached near an edge, it could be very appropriate using some tab routing variation, rather than v groove pcb panels. Just make sure that you don’t locate the tabs close to the edge components.

Board Shapes

Mouse bites PCB shapes that are added to any array usually play a significant role in panelization. For rectangular and square boards, v groove PCB panels work very fine. When dealing with unusual shapes, the better is tab routing.

Time Expense

Setting up tab routing takes more time. This is because the router requires much time. V groove, while under machines requires lesser time.

Edge Quality

The fact is, if the edge quality stands as a factor then tab routing may be more preferred to v grooving. Although, working with this process leaves back small rough laminate rubs, you can easily sand them off. Then the edges remaining are smooth. V grooving causes rough edges around. If you require smooth edges, this may need more sanding.

Waste

If you are concerned about material waste, then the best benefit will be provided by v grooving. Compared to tab routing, this method wastes less material. This means the overall cost for each board will be much lesser.

Mouse Bites PCB Manufacturer

When setting the manufacturing panel up for printed circuit boards, there are lots of variables to work with. This is why your mouse bites PCB manufacturer must have much experience in this.

Your manufacturer will tell if a breakout panel or V-groove will suit your design best based on the design criteria and the specific needs of the board. Also, they understand the needs of your business and also tailor the creation of the panel in line with your expected volumes of production, as well as the specific requirements of the board.
