FastImmunity: An EDA extension for PCB immunity prediction

Predicting the immunity of printed circuit boards (PCBs) to radiated electromagnetic interference (EMI) requires the computation of the electromagnetic field's coupling to PCB traces. A modified Taylor-based analytical model exists developed and validated for PCB's immunity prediction. In this paper, we present the methodology of development of an electronic design automation (EDA) extension for Altium Designer based on the prediction model. The developed extension allows PCB designers to have further insight on PCBs immunity during design phase and implements a unique electromagnetic compatibility (EMC) feature compared to existing EMC tools.
