Abstract

This paper deals with the effects of radiated EMI on serial communication links using software modelling with particular emphasis on the physical layer. The effect of EMI in data links is an important problem to solve in many harsh environments such as the automotive and the transport sector as well as communications, in fact the EMI effect is able to produce sampling errors in digital/binary operations. Currently binding standards prefer the analysis in frequency domain to account for EMI impact, however when dealing with data links, time domain analysis might report useful information, therefore a link between those two is needed. The cable models are developed using SACAMOS modelling software, taking into consideration the frequency parameters. The model can be used on almost any SPICE simulator to analyse the effect of EMI. The simulations performed in this research are verified on a real laboratory experiment in order to demonstrate the capabilities of SACAMOS.
