One major thing that separates OrCAD from the lower end CAD packages is the PSpice add-ons that allow full circuit simulation.
It does have quite a learning curve but if you have it at your disposal, it can save you a ton of time and frustration on some of the more advanced mixed signal designs. There are even entire courses in college focused on just learning how to use this one feature.
One drawback of OrCAD is how it splits up every feature into standalone applications. Each feature has its own program; nothing is integrated.
This is a little annoying and you’ll find yourself toggling between several windows when developing 1 board.
Its 3D rendering isn’t the greatest (compared to Altium), but it works. OrCAD is very powerful and an industry standard, but it’s just a little outdated in our opinion.
