Abstract:
EMI/EMC failures contribute to around 30% of the failures in the verification stage costing the electronics industry billions in lost revenue. Today, in general, EMI/EMC compliance is met by preparing a prototype and performing measurements in a standard laboratory. If the Equipment-Under-Test (EUT) fails compliance, the engineer has to diagnose the problem, modify the design, and re-prototype. This leads to delay in time-to-market and canceled projects. EMI/EMC system simulation is used rarely unlike in Signal Integrity/Power Integrity problems where simulation is predominant. The reason can be attributed to: (a) the time and memory complexity of a full-system simulation and (b) the lack of system-level models in particular for ICs. In this presentation, a model-based system-level simulation approach for EMI/EMC will be discussed. Models of different components of an EMI/EMC laboratory are generated and fed into a hybrid 3D and 2D electromagnetic simulation framework. Examples of models include: (a) IC models in the form of ICIM (IEC-62433-4) and ICEM-CE (IEC-62433-2) and ICEM-RE (IEC-62433-3) and (b) proposed ECU and off-ECU models. New research in generation of operating condition dependent models will be discussed.
