Abstract :
Model reduction is a popular approach for incorporating detailed physical effects into high level simulations. In this paper the author presents a simple method for automatically extracting macromodels of nonlinear circuits with time-varying operating points. The models generated are truly “reduced” meaning that the complexity of macromodel evaluation is not strongly dependent on the size or complexity of the original detailed circuit description
