"Top-Down" Design Flow and Its Applications in Multi-Vehicle Communication System's EMC Design

The top-down electromagnetic compatibility (EMC) design flow and its applications in multi-vehicle communication system, which is based on EDA software, are introduced. For the EMC problems such as antenna interaction, enclosure leakage and radiation of printed circuit board (PCB) in a four-vehicle communication system, the design flow from system level and device level to PCB level is present with simulation procedure. The results show that this design flow can obviously improve the electromagnetic immunity of the system and make the design first pass success.
