本文对CMOS门阵自动布图设计系统中的总体布线器作了简单介绍。本文提出的总体布线算法不仅能用来解决一般的门阵总体布线问题,而且对我们开发的大规模集成电路(LSI)自动布图设计系统更显出其优越性。我们所选择的总体布线器的目标函数,与整个布图系统的总目标是非常一致的,同时,应用了许多有效的新方法来使总体布线器的目标得以实现。 This article made a brief introduction of the overall router in CMOS door array automatic layout system. The proposed overall routing algorithm not only can be used to solve the general gate array routing problems, but also to our development of large scale integrated circuit (LSI) automatic layout design system even more shows its superiority. The objective function of the overall router we choose is very much in line with the overall goal of the overall layout system. In the meantime, there are many new and effective ways to make the overall router’s goal possible.
