一、引言随着集成度的提高,IC(集成电路)版面图形越来越复杂,因此版面设计的自动化也显得越来越重要。特别是对于专用IC的设计,近年来适用于专用IC设计的元胞法、门阵列法迅速发展,出现了许多IC自动设计系统。本文介绍一个我们自己开发的、能在小型计算机上运行的标准元胞法集成电路版面自动设计系统MPR。所用的单元为等高不等宽的标准 I. INTRODUCTION With the improvement of integration, the layout of IC (Integrated Circuit) is more and more complicated, so the automation of layout is also becoming more and more important. Especially for the design of special ICs, the cellular method and gate array method suitable for the design of special ICs have been developed rapidly in recent years, and many IC automatic design systems have appeared. This article presents a self-developed MPR for a standard cellular IC layout automation system that runs on a small computer. The units used are of unequal contour
