Methods for circuit-based automotive EMC simulation incorporating VHDL-AMS models

This paper provides an overview of several novel approaches to enhance todaypsilas automotive EMC simulation. The introduction of fast and efficient modeling and solving techniques for models of passive PCB traces leads to an improved computational performance. Additionally, the development of a methodology enabling co-simulations of VHDL-AMS models of active IC devices yields more accurate numerical results. After the explanation of these enhancements, the proposed simulation flow and analysis methods are shown by means of numerical results from a typical automotive application.
