Abstract :
A new multirate algorithm for circuit simulation that combines the efficiency of event-driven techniques with the simplicity of explicit integration to successfully decrease the overall run-times, is described. The method uses discretization in the voltage axis and exponentially fitted integration formulas to avoid stability problems inherent to traditional explicit integration schemes, and uses a new and effective step control algorithm to take full advantage of the multirate behaviour of large circuits and further increase the performance of the simulation
