To understand PSpice 9.1, it's helpful to know its origins. The tool's foundation is SPICE (Simulation Program for Integrated Circuits Emphasis), which was originally developed at the University of California, Berkeley in the 1970s. PSpice was a PC-based version created by MicroSim Corporation. In 1998, MicroSim merged with OrCAD Inc., and in 1999, OrCAD was acquired by Cadence Design Systems Inc. PSpice release 9.1 was the first version released after Cadence acquired OrCAD. pspice 9.1 student version free download
