Electrothermal co-simulation of a two-chip power delivery network in frequency domain

Abstract

In this paper, the electrothermal characteristics of a two-chip power delivery network (PDN) structure is investigated by using a frequency-domain co-simulation solver. The solver is developed based on finite element method (FEM) by circularly solving the wave equation for a full-wave electromagnetic analysis and the heat conduction function for the thermal analysis. A bandstop filter is used as an example to verify the accuracy and efficiency of the programs. Then the effect of metal and dielectric losses on the electrothermal characteristics of the PDN is emphatically studied. The electric field and temperature profiles on the resonance frequency are given out.
