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 analysis.
