Electromagnetic emission simulation evaluation — A use case

The compliance of E/E products to Electromagnetic Emission (EME) standards is verified by emission measurements using a defined test setup including electromagnetic interference receivers (EMI Receivers). More and more, EMEs are also considered and simulated during the product design phase. Consequently, the behaviors of all components that are required for an Electromagnetic Compatibility (EMC) test have to be included in the simulation which includes the EMI Receiver model. This paper presents the usage of an novel EMI Receiver model on an airbag control unit use case. With a new guidance for choosing the correct simulation time meaningful emission results can be achieved. The results show a good match between simulation and measurement. Major deviations are due to not modeled components and parameter variations.
