Pulsonix PCB Design Software

The Pulsonix is the classic software available online with free trial version 10.5. This include schematic capture, spice simulator, PCB layout, auto router, chip packaging toolkit, library integration toolkit, embedded components, Micro-Vias, Interactive high speed, Spirals and Database Connection (PDC) Trial. Please visit pulsonix.com to download your own copy.

Software Interface:

As we open the software, it shows the window with Design, Technologies + Profile and Wizard options. Choose File >> New >> Design >> Schematic Design

You can open the example schematic from

File >> Open >> User >> Documents >> Example.sch

I opened the notch filter schematic and it look like this

Pulsonix Tutorial:

Here we can see many tool available.

On the left hand side, there is a vertical tool bar.

This symbol  is the component library placement. Left click on this and library window will appear.

The “Filter” option with asterisk mark gives you flexibility to enter the keyword for the component you are looking for. Click “Apply” to activate the filter. In the “look in”, a drop down menu will show the list of all manufacturers available with their libraries. The manufactures are listed A to Z and in “Generic” you will find generic capacitor, resistors, diodes, transformer, fuse, crystal and zener diodes. The special thing is that the component footprint is also mentioned in the box and component designator and component symbol is also shown.

Pulsonix Tutorial:

You can click on the “Preview” check mark to show or hide the component symbol and you can also check mark the Schematic & PCB to hide or show the component footprint. This is very useful to see what footprint will be used in PCB layout design。


Panning / Zooming:

Left click and depressed and move your computer mouse to “Pan”. Scroll Up to zoom in and scroll down to zoom out


Inserting Connector Pin

You can insert the connector pin same as the component. Part number, description, total number of pins, family, footprint, symbol and name are shown in the window. You can use filter to select the connector pin of your choice. You have to click “Add” to place the pin on the schematic sheet.

You can change the pin number from here. The pin placed on the schematic is pin number 5 of the connector part number shown in below diagram. The connector however is 24 pin total.

Insert Document Symbol:

You can insert the page border and symbol with description with various sizes like A, A1, A2, A3 and A4 and B, C and D landscape borders.

Pulsonix Tutorial:

Click Add to place the symbol.

Inserting the Signal Reference:Pulsonix Tutorial:

The signal references like +5V, 12V, 15V, Ground, common, earth, box, input, output, pointer, terminal, VCC, VDD and VSS.

These signal reference are very important in any circuit design hence can be placed by clicking here  on left menu.

The symbol in previous section can be placed by clicking here  on left menu

The connector pin can be placed by clicking here  on left menu.

The bus bar can be placed by clicking here  on the left menu

The bus bar is used commonly in microprocessor or memory circuits where I/O s are too many.

Connecting the Components Together:Pulsonix Tutorial:

You can connect your components by clicking here  on the left menu. This is the wiring connection. When you connect the nodes together or connect nets then a confirmation prompt will occur. Click OK to continue.


Place Text:

You can also place text on current sheet by clicking here

Pulsonix Tutorial:


Electrical Rule Check: (ERC)

You can run the electrical rule check on the schematic you design and check the following parameters. Pin type rules, busses, hierarchy, unfinished nets and unfinished connections. There are other checks that you can mark according to your requirements

Pulsonix Tutorial:

Click on Check to run the ERC. A report file in text document will be generated showing errors and warnings if any.


Test Point:Pulsonix Tutorial:

You can insert the test points Insert >> Test Point

Click on any point/wire/junction in the circuit and a green color line will appear then click anywhere on the schematic to drop the test point.



Page Link:

If your schematics is on more than 1 page, then you can insert page link by Insert >> Page Link


Changing Units:

Setup >> Units >> Imperial or Metric



Setup >> Grids >> Basic Step, Multiplier, Divisor, Step and display


Top Menu:

This menus has the new, open, save, print, setup folder, library, technology, colors and options in the sequence from left to right as shown.

Simulation:Pulsonix Tutorial:

As we know that Pulsonix offers schematic capture, simulation and PCB layout. So here we discuss simulation aspect.

Simulation >> Set Netlist Spice Type

Here you can set the netlist spice type form different options Basic Spice, LTSpice, PSpice, Pulsonix Spice and SIMetrix. Select the Pulsonix Spice.


Insert Source:Pulsonix Tutorial:

For simulation we know that the circuit needs inputs source. Go to Simulation >> Insert Source, a drop down menu will show many options like power supply, waveform generator, AC voltage source, DC current source, CCCS, CCVS, VCCS and VCVS.


Insert Part Using Model:

There are parts that do not have spice models and many others have. So you can choose only those components definitely having spice models.

Simulation >> Insert Part using Model

Pulsonix Tutorial:

This window will open. You can choose the type of component from left panel and select the part number and component symbol is also shown in bottom.



Insert Probe:

You can insert the fixed probe in your schematic to run the transient or AC analysis parameters. Go to Simulation >> Insert Fixed Probe

Pulsonix Tutorial:Pulsonix Tutorial:

A drop down menu will open showing the options shown in this figure. There are various types of probes like voltage probe, differential voltage probe, current probe, bus probe, voltage dB and Voltage phase probes etc.


Simulation Parameters:

You can change the simulation parameters from

Simulation >> Simulation Parameters

This has transient, AC, DC, Noise. Transfer Function (TF), Options and Safe Operating Area (SOA)

Pulsonix Tutorial:

Like for AC analysis, you can set the start, stop and points per decade for simulation. Method can be decade or linear. Check mark the simulation type on the right side you want to run. Then press F9 to simulate the circuit
