Altium Vs Cadence – What is the Difference?

User Interface

An unattractive user interface for PCB design software can be very annoying. You can have a bad experience with things like terrible color palettes. A poor user interface is really a thorn in the flesh. Altium features a great approach to PCB design. Its user interface makes your experience a lovely one. You will enjoy working in the tool in Altium Designer. This is because it feels really great and the choice of color is something you would love.

However, this is not the case with Cadence Allegro/OrCAD as it does not offer users with an enjoyable user experience. The user interface isn’t what you would really like. However, this does not mean this software isn’t powerful or efficient enough. Once you use it correctly, you will enjoy your work, but it’s not an application you will love to play around in.

Altium enhances the experience of the user as the work progresses. However, Cadence Allegro works like a pick up truck that can perform more heavy lifting for you. Also, Cadence is very amazing for work, but it isn’t what you would like for taking pictures.

Help & Documentation

A helpful documentation is necessary in every PCB design software. It serves as a guide. This means it tells you what a thing is and how to use it giving examples. This really saves you so much time. Nobody likes to waste time on things when they don’t know how to do it. A good documentation is really a life saver.

The documentation in Altium Designer offers great context on the reasons you should utilize a feature in the tool. Also, it gives example on how to go about it. However, users have to visit their website to find what they are looking for. Also, users must be sure of the particular term they are looking for. Sometimes you might not know how to describe the particular term in Altium. In this case, you need to go through the categories in the documentation. You may likely come across something that gives answers to the problem. This is not convenient to do in Altium.

 Allegro/OrCAD makes this more convenient.  When you click the ‘Help’ button in the window you are working in, the documentation brings out what you need. Also, Cadence Allegro allows you to learn the terms of those features. Also, it provides examples on how you can use them.

Ease of Use

Ease of use can be classified in two different ways. The first is, how you can easily integrate the rule manager. Secondly,  how easy can users apply rules for the circuit board. It is much more intuitive to set up rules in Altium Designer than it is in Cadence. But, there are more considerations to take when applying the rules. This includes having to script/code a rule and managing rule priorities.

The constraint manager of Cadence Allegro is no way intuitive to use. This is because this feature requires some training or tip. You can easily make rules once you understand how the tool works.  

Efficiency During Design

You need a constraint management system/tool that doesn’t require you to keep updating. Once you set up a constraint management system, you don’t need to update it.  

Altium Designer is a perfect software that works excellently when making constraints that make intuitive sense. The graphics and images are useful and helpful along the way. However, once you work with any high-speed design, you will need to include a code to help manage some differential pairs, constraints, net classes, etc. After this, you can now set the priorities.

However, this isn’t the case in Cadence Allegro. Everything is completely different.  The constraint manager enables  you to create several constraint sets. You can assign these constraint sets to any group of your choice. This is a simple and efficient method to set constraints. Another great thing  is when you can change a constraint for any object in your design  without code. However, you can still set some special constraints using code.

You need to be very careful of the Constraint Manager tool in Altium designer, especially the constraints is set for certain boards.  In cadence Allegro, all you need is to set it from the top level to the ground level. This makes it very effective.

Reliability

Reliability is one of the most crucial benefits you need in any EDA software. The ability for users to trust that  the software won’t make mistakes while working on their PCB project is a great assurance. This is because errors can be a nightmare for you as you will need to spend your precious time fixing those errors. Not only the time involved, the effort involved in correcting errors is exhausting.

The rule management of Altium Designer is indeed a great feature that helps you to keep your design in check. But, there is one major concern for users. This is the number of custom rules users need in  creating with code.

Cadence Allegro is really a reliable software as it changes the whole story. Users can see everything constrained by simply integrating the spreadsheet-based approach to rule management. Furthermore, the sets-based  group-based approach of Cadence to constraint management  is very simple. This approach is very effective and powerful.

Also, Cadence Allegro allows you to set certain parameters on every net. However, the rule management system of  Altium requires you to create it and always come back to check.

Custom Constraint Regions/Areas

Most PCB design software allows you to set any region on the circuit board with.  Altium Designer makes it easy to design custom constraint areas/ regions. All you need to do is to build a Room object, then place it on the printed circuit board and design a new rule set that defines where the rule is applicable.

Cadence Allegro features Constraint Region boxes that allow users to design a custom rule area. Also, users can place that region in a ‘Constraint Set’. The two methods are very easy to carry out. However,  the OrCAD’s method is preferable since it allows you to reuse the special region constraint set any time you want.

Which of the Them Suits You?

Job Seekers

Cadence Allegro is a reliable option if you will be working in any Corporate Industry. It is very difficult to see a large company, which doesn’t talk about the Cadence Allegro software whenever they mention Altium.

College Students

Students in the college ought to learn how to use Cadence or Altium. Usually, the industry desires freshly graduated engineers that know how to make use of the software.

Conclusion

By now, the features and differences between Altium and Cadence are very clear. Work with whichever suits your work and projects.
