Abstract
In highly integrated electric circuits only a few elements are stimulated by an input signal. The major part of basic elements remains latent. The latency can be exploited on the numerical simulation level by partitioning or by multirate strategies. Advantages and disadvantages of both approaches are discussed. It seems that multirate integration schemes, which use different step sizes for the active and the latent components, are more promising. Furthermore, a combination of partitioned and multirate schemes forms a base for a parallel evaluation. The inverter chain serves as a typical example for which partitioned Runge-Kutta methods and multirate Rosenbrock-Wanner schemes have been tested.
