Comparison of Matrix and Circuit Partitioning Approaches for Analysis of Large Scale RLC Circuits

摘要

Fast simulation techniques of large scale RLC networks with nonlinear devices are presented. When scale of nonlinear part in a circuit is much less than the linear part, matrix or circuit partitioning approach is known to be efficient. In this paper, these partitioning techniques are used for the conventional transient analysis using an implicit numerical integration and the circuit-based FDTD method, whose efficiency and accuracy are evaluated.
