Abstract

This paper describes an electromagnetic interference (EMI) simulation of radiated emissions caused by simultaneous switching noise in an irregular power/ground plane structure. For quick simulation of the radiated emissions from the power-bus edges, we used a series of analytical approaches: power-bus resonance characterization by a fast algorithm based on a cavity-mode model and a segmentation method and radiation calculation using equivalent magnetic current based on the field equivalent principle. The analytically based radiation calculation is achieved within a few minutes on a single personal computer and agrees with the actual measurements. Furthermore, this paper demonstrates an EMI simulation with and without decoupling capacitors by using a linear macro model of an integrated circuit as a noise source. We found a fair agreement between the simulation and measured results.
