摘要

研究了宏单元布局集成中通道边界网的交叉分配问题。作者解决这个问题的方法既针对全局标准(总面积、净长度),也针对局部标准(改进的通道可达性)。这是通过两阶段算法完成的。在第一阶段,捕获所有全球需求。第二步,在考虑特定信道和信道路由器需求的同时,解决所有冲突的需求。该算法是Laysys的一部分,Laysys是一个布局集成系统,用于设计剑鱼ULSI微处理器。

Improved port assignment on channel boundaries
Deals with the task of assigning the crossing of nets on channel boundaries in the layout integration of macro cells. The author's approach to this problem targets both global criteria (overall area, net lengths) and local criteria (improved channel routability). This is done in a two-stage algorithm. In the first stage, all global needs are captured. In the second, all conflicting needs are resolved while taking the specific channel and channel router needs into account. The algorithm is part of Laysys, a layout integration system which was used for the design of the Swordfish ULSI microprocessor.<>
