PSpice
Top
(Simulation Program with Integrated Circuit Emphasis) A program widely used to simulate the performance of analog electronic systems and mixed mode analog and digital systems. SPICE solves sets of non-linear differential equations in the frequency domain, steady state and time domain and can simulate the behavior of transistor and gate designs. Developed at the University of California at Berkeley in the mid-1970s, there are enhanced versions of SPICE provided by several software companies. PSpice is a version for personal computers such as DOS, Windows and Mac.

PSpice is a SPICE analog circuit and digital logic simulation program for Microsoft Windows. The name is an acronym for Personal computer Simulation Program with Integrated Circuit Emphasis.
History
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.
Features
During its development, PSpice has evolved into an analog mixed signal simulator. The software, now developed towards more complex industry requirements, is integrated in the complete systems design flow in OrCAD and Cadence Allegro. It includes features such as analysis of a circuit with automatic optimization, encryption, a model editor, support for parametrized models, auto-convergence and checkpoint restart, several internal solvers, a magnetic part editor, and support for Tabrizi core model for non-linear cores.
