摘要

Accurate modeling of conductor roughness is crucial for signal integrity analysis. Various models have been proposed in the literature, while many of the commonly-used ones are not causal, meaning that the time domain waveform will have nonphysical precursors before the actual arrival of the signal. The causality issue has been addressed in a few papers, while there is a lack of a thorough comparison between the available models. In this paper, through a 7-inch microstrip line example, we compare the causality of six models: Hammerstad, modified Hammerstad, causal Hammerstad, hemisphere, Huray, and causal Huray. It is found that the hemisphere and Huray models can have a> 10 mV precursor, the Hammerstad models have smaller precursor (<4 mV) due to its fast saturation, whereas all causal models have no precursors.
