An EMI Receiver Model to Minimize Simulation Time of Long Data Transmissions

Abstract

For evaluating the electromagnetic emission (EME) of an integrated circuit (IC) during the design phase, a precise transient simulation of the disturbing signal is required. This usually takes a lot of time, so that simulating a signal trace longer than a couple of ms is not feasible. In this paper an extension to an existing electromagnetic interference (EMI) receiver model is introduced, which enables to interpolate the emission spectrum of very long transient data with repetitive contents (like digital data transmissions) while using only short parts of the overall signal as input. Therewith the IC simulation time can be reduced by far without losing accuracy in the EME post-processing stage.
