Simulation methods for signal integrity of automotive bus systems

Automotive bus systems like FlexRay or CAN have to provide correct functionality for safety critical applications under various circumstances. In addition many parameters can influence signal integrity. To ensure correct behaviour under all given conditions, simulation based analyses are performed. In this article it is presented how simulation models have been developed, automated workflow and signal analysis have been implemented and parameter search methodologies have been chosen and adapted to provide tools for validation of bus system topologies.
