The design of any circuit board requires very specific software. There are many things that have to be taken into account, like the fact that circuit boards can vary in kind, from analog to digital, or be a combination of both. OrCAD is an application that has been specifically developed to design circuit boards. And to test the designs that we create with OrCAD, we'll need an application like PSpiceA/D Circuit Simulator.
PSpice is a simulator that analyzes the behavior of a virtual circuit board, using the Smoke method to detect the components that could be at risk due to overstress, and the Monte Carlo method to determine how the components perform, thus preventing any board failure.
Furthermore, it includes advanced simulation technology that will allow all users to save plenty of time and get more reliable results when working with large designs.
If you need a tool to simulate how an analog or mixed-signal circuit board behaves, download PSpice and try it out.

The trial version has certain limitations.
