Parallel-distributed time-domain circuit simulation of power distribution networks with frequency-dependent parameters
2006
In this paper, we focus on the verification of the PCB/package power integrity, which becomes very important for the design of state-of-art high speed digital circuits. The simulation of power distribution networks (PDNs) of the PCB/package, which can be modeled as a large number of RLC lumped components, is a time-consuming task for using the conventional circuit simulator, such as SPICE. For this problem, we propose a parallel-distributed time-domain circuit simulation algorithm based on LIM. Furthermore, an effective modeling of frequency-dependencies of the PDNs, such as skin effects and dielectric losses, to solve by LIM is proposed
