PSPICE for Windows

SPICE - Simulation Program with Integrated Circuit Emphasis

Developed by EE and Computer Science departments at UC Berkeley

Computer-Aided circuit analysis and design tool capable of performing several different types of analysis, including dc, ac, and transient analysis

PSPICE is PC-SPICE, or SPICE for the personal computer, is a comprehensive software system sold by Microsim (now a part of OrCAD) which includes several different components

Starting PSPICE

Schematics is a schematic capture tool which allows a user to describe a circuit graphically. In addition, the various analysis options and other tools can be launched from Schematics.

PSPICE for Windows

Several example circuits will be used to demonstrate how to use Schematics and PSICE to analyze circuits.
