Abstract

SPICE-PAC is a package (or a set) of subroutines which is functionally equivalent to the SPICE 2G circuit simulation program, i.e., it accepts the same circuit description and performs all the analyses which are available in the SPICE 2G programs, but also provides an access to internal values of circuit elements, dynamic definitions of parameters and outputs, hierarchical naming scheme for subcircuit elements, parameterized subcircuit expansions, an interface to libraries of standard modules, and a set of run-time diagnostics to control the package actions. Two immediate applications of the package are: (1) interactive circuit simulation in which an interactive driver controls the simulation subroutines according to user commands, and (2) circuit optimization in which an optimization package is interfaced with the simulation package by user-supplied subroutines that evaluate objective functions, constrains, etc. Some results of very simple examples are included as an illustration.
