摘要

提出了一种非保形域分解方法(DDM)来研究多尺度、多层印刷电路板(PCB)上高速互连的信号完整性。通过对四层差分对的分析,首先证明了该方法的准确性和鲁棒性。然后,我们研究了一个14层16走线互连模型,以证明该方法的有效性。研究了时域SI中两种模型的眼图。

High speed interconnects of multi-layer PCB analysis by using non-conformal domain decomposition method
A non-conformal domain decomposition method (DDM) is proposed to investigate signal integrity (SI) of high-speed interconnects on multi-scale, multi-layer printed circuit board (PCB) in this paper. The accuracy and robustness of the proposed method is first demonstrated by analysis of a 4-layer differential pair. Then we studied a 14-layer 16 traces interconnect model to demonstrate the efficiency of the method. Eye diagrams of the two models are studied for time domain SI.
