摘要
本文介绍一种新的四边通道布线器(DDCR),该布线器基于启发式原则提出,并应用动态布线密度和约束图完成线网定序和连线段选择。DDCR是H/V方式布线,该程序由C语言写成,运行于VAX11/780VMS下,可与BBL2布图系统配套使用,通过对许多例子试验,其效果是满意的。
A ovel switchbox router,DDCR,is described in this paper. Based on the heuristic principle,it features a dynamic routing density and constraint graph to complete the ordering of nets as well as the selection of routing segment. In this router,routing is done by H/V method,and is implemented in C language on VAX11/780 under VMS operating system. DDCR can be used with BBL2 layout system. Satisfactory results were achieved in a number of experimental applications.
