Abstract :
A novel symbolic circuit analysis strategy, its matrix reduction, and its numerical approximation during computation methodologies are presented. These methods have been implemented in Sspice version 2.0. Together with the unique decomposition approach of Sspice 2.0, Sspice has successfully analyzed the full schematics of commercial op-amps and power regulators in developing their macro-models. The matrix reduction scheme and numerical approximation are presented in order to improve the efficiency of computation and memory consumption
