Multi-rate parallel circuit simulation

Abstract

The invention discloses a multi-rate parallel circuit simulation method and system. The method implemented by a computer comprises the steps that a circuit is divided into multiple partitions, wherein each partition is represented by a set of linear differential equations; the simulation time step of each of the multiple partitions is determined; the multiple partitions form a plurality of sets, wherein each set comprises one or more partitions with the simulation time steps within the preset definition range; the equation of the multiple sets is solved through the corresponding simulation time steps in a parallel mode.
