HYPAC: a hybrid-computer circuit simulation program

Computer simulation of electronic circuits and systems has become an increasingly important tool in circuit and system design. Such simulations enable one to: 1. Eliminate the necessity of building many breadboard models in order to evaluate different design approaches. 2. Analyze the performance of the circuit as a function of different parameters. 3. Model semiconductor devices and integrated circuits so that intrinsic parameters become accessible. 4. Perform optimization and tolerance analysis of a circuit which requires many evaluations of the circuit with different sets of parameters.
