ＶＬＳＩ电路中，深亚微米工艺及多层布线技术的广泛应用使互连寄生效应成为制约电路性能的主要因素，直接边界元素法３－Ｄ寄生电阻电容提取的计算量很大，采用并行计算是快速提取的重要途径之一。本文介绍运用ＰＣ机网络计算软件ＰＶＭ实现寄生电阻电容线性元分布式计算的方法，讨论了线性方程组建立和求解过程采用的并行计算方案。最后，对算法的并行效率及负载平衡作了分析。
VLSI circuit, deep sub-micron technology and multi-layer wiring technology is widely used so that the interconnection parasitism has become the main factor restricting the performance of the circuit, the direct boundary element method 3-D parasitic resistance capacitance extraction is a large amount of computation using parallel computing is One of the important ways to extract quickly. This paper introduces a method to calculate the linear element distributed parasitic resistance by using PCM network computing software, and discusses the parallel computing scheme used in establishing and solving linear equations. Finally, the parallel efficiency and load balancing of the algorithm are analyzed.
