本文提出了一种在通道内将Ｐ／Ｇ网与信号网的实体布线一体化考虑的优化布线策略，目的是在保证１００％布通的前提下，完成Ｐ／Ｇ网的平面化实体嵌入和信号网的实体布线，并使Ｐ／Ｇ走线对信号网走线的影响尽可能小。算法以提高布线区利用率、减小通道高度和减少通孔数为目标，实现总体性能的优化。系统实现的结果表明，本文算法所采用的策略是可行的、有效的。 In this paper, we propose an optimized routing strategy that integrates the P / G network with the physical network of the signal network in the channel. The purpose of this paper is to complete the planar physical embedding of the P / G network under the premise of ensuring 100% Signal cabling entity wiring, and make P / G alignment on the signal line alignment as small as possible. The algorithm aims to improve the utilization of the wiring area, reduce the height of the channel and reduce the number of vias, so as to optimize the overall performance. The results of system implementation show that the strategy adopted in this paper is feasible and effective.
