摘要
本文介绍了一种全波电磁干扰模拟器BLESS (Board Layout Evaluation and Suggestion System)，用于考虑电磁兼容性(EMC)和电源/信号完整性的印刷线路板设计。该仿真器基于并行分布时域有限差分(FDTD)方法，工作在pc机集群上。通过与s参数测量的比较，验证了BLESS分析的准确性。利用该仿真器，对商用数码相机中多层印制电路板进行了全波分析。利用假设分析结果，可以在较少的试制次数下验证和优化压路板设计。
What-if analyses of multi-layer PWB embedded in the digital still camera with parallel-distributed FDTD-based simulator "BLESS"
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.
