Abstract :
This paper describes a full-wave EMI (electromagnetic interference) simulator BLESS (Board Layout Evaluation and Suggestion System) for the printed wiring board (PWB) design with the consideration of electromagnetic compatibility (EMC) and power/signal integrity. This simulator is based on the parallel-distributed finite-difference time-domain (FDTD) method, and works on a PC-cluster. The accuracy of analysis by BLESS is verified in comparison with s-parameter measurements. Using the simulator, the full-wave analysis of the multi-layer PWB in a commercial digital still camera is demonstrated. With the aid of what-if analysis results, PWB design can be verified and optimized with less number of trial productions.
