Pspice TUTORIAL
Orcad is basically a tool for drawing Schematics. However, it can also be used to simulate circuits. In many cases it is required that you simulate the cicuit before releasing it. It minimizes the chances of errors and respin in the board.This tutorial is expected to give you enough knowledge , so you can start simulating circuits. We do not intend to cover the elecrical and electronics part of the circuits, which is a deep and wide topic. Instead, we will work with simple common circuits that will get you started on Orcad tool. You can then extend the idea to any complex circuit that you wish to. The tutorial is basically to make you familar with the Orcad's simulation capability.
Pre Requisite
You should be familiar with OrCAD Circuit drawing tool. If not, you can take a quick tutorial here
