A Parallel Simulation Technique of Interconnect Networks with Frequency-Dependent Parameters Based on Equivalent Circuit Models

Abstract

Abstract: A parallel algorithm was presented to satisfy the demand of efficient simulation of complex interconnect networks with frequency-dependent parameters. By means of the equivalent multi-port models, the interconnects are separated from other circuit elements, and thus makes the parallel simulation feasible. The finite-difference time-domain method is utilized for the solution of interconnects while other circuit elements are simulated in the simulation program with integrated circuit emphasis（SPICE）environment, and their simulation results are exchanged in every time step. Based on the proposed technique, a program named FdSPICE was developed for parallel simulation of interconnect networks. The numerical examples show that accurate results are obtained by this program and the simulation efficiency is improved significantly.
