FdSPICE: A parallel simulation technique for lossy and dispersive interconnect networks

This paper presents a parallel algorithm for the simulation of large complex interconnect networks with frequency-dependent parameters. The equivalent transmission line model, which is suitable for time-domain simulation, is introduced for the modeling of dispersive interconnects. By means of the equivalent multi-port model, the interconnects are separated from other circuit elements, and thus makes the parallel simulation feasible. Based on the proposed technique, a program named FdSPICE is developed for parallel simulation of large interconnect networks. The accuracy and efficiency of FdSPICE are demonstrated by numerical examples.
