Introduction to PSPICE

■ History of SPICE▶ Spice(Simulation Program with Integrated Circuit Emphasis) –

1972 from California Univ. For Workstation, etc

▶ PSpice(Professional Simulation Program with Integrated Circuit Emphasis) – 1984 from MicroSim Co.

Usable in Personal Computer

▶ PSpice v5.2 – 1992▶ PSpice v6.0 – 1993▶ PSpice v6.2, v6.3 – 1995▶ PSpice v7.1 – 1996

4

▶ PSpice v8.0 - 1998▶ ORCAD PSpice Release v9.0 – 1998 from OrCAD Co.▶ ORCAD PSpice Release v9.1 - 1999 from OrCAD Co.

Currently, Pspice Version 9.2 is used for circuit anal

ysis.
