VLSI版图设计中的一种优化总体布线方法

A Optimal Global Routing Method in VLSI Layout Dosing

本文针对国际上已有的多种BBL总体布线方法进行了研究,提出了一种更有效的基于多子图定向合并生成的布线算法,并在国家重点工程“熊猫系统中实现.实验结果比较表明:我们的总体布线优化技术优于已有的BBL总体布线工具.

On studying most of global routing methods, we present a more effcicnt global routing algorithm. The main id(?)a of the algorithm is multiple components growth and directional merge method. Our global routing system has implemented in PANDA system, whith is a national major project. Experimental results show that our global-router has achi(?)ved very small chip area and total net length in short running time. Our global- router is superior to others.
