Questions tagged [pspice]

PSpice is a SPICE analog circuit and digital logic simulation program for Microsoft Windows. The name is an acronym for Personal Simulation Program with Integrated Circuit Emphasis.

PSpice was initially developed by MicroSim and is used in electronic design automation. The company was bought by OrCAD, which was subsequently purchased by Cadence Design Systems. PSpice was the first version of UC Berkeley SPICE available on a PC, having been released in January 1984 to run on the original IBM PC. This initial version ran from two 360 KB floppy disks and later included a waveform viewer and analyser program called Probe. Subsequent versions improved on performance and moved to DEC/VAX minicomputers, Sun workstations, Apple Macintosh, and Microsoft Windows.

Version 3.06 was released in 1988, also came on two 5.25 floppy discs, and had a "Student Version" available which would allow a maximum of up to ten transistors to be inserted.
