Abstract

The numerical simulations of power integrity in electronic packages become more and more significant, which help us to understand the characteristic of power distribution network. In this work, a simple and efficient method synthesizing 2D generalized transmission line equations (GTLE) and finite-difference frequency-domain (FDFD) is proposed for power integrity simulation. The combined method can simulate power/ground plane pair surface mounted with lumped circuit elements such as decoupling capacitor. Several numerical results are presented compared to HFSS. Validation of the proposed method is demonstrated by the results.
