Modular circuit simulation with integrated applications

Abstract A modular approach to circuit simulation is proposed in which the traditional “closed” structure of circuit simulators is replaced by a collection of loosely coupled “simulation primitives” which can be combined in different ways, depending upon a particular application. An implementation of this approach, the SPICE-PAC simulation package, is described. SPICE-PAC is compatible with the popular SPICE circuit simulator, but it also supports a number of extensions and refinements which are not available in the original SPICE-like programs. Several integrated applications are discussed in greater detail to illustrate the flexibility of the proposed approach.
