What is SPICE?

History of SPICE

SPICE is open-source software that simulates the operating conditions of analog circuits.
It is short for 'Simulation Program with Integrated Circuit Emphasis'.
Developed by the University of California, Berkeley in 1973, SPICE has undergone changes as shown in the table below to reach its current format.
The first version, SPICE1, was coded in FORTRAN.
The most popular SPICE simulator is based on SPICE2G.6 and is written in C.

Year SPICE Version Language
1973 SPICE FORTRAN
1975 SPICE 2 FORTRAN
1981 SPICE 2G.6 FORTRAN
1985 SPICE 3 C

FORTRAN is a procedural programming language developed for scientific computing.
It facilitates optimization of parallel computing operations to achieve faster processing speeds.
During that time programs were executed on large-scale computers (mainframes).
