Track Assignment Considering Crosstalk-Induced Performance Degradation
MetadataShow full item record
Track assignment is a critical step between global routing and detailed routing in modern VLSI chip designs. It greatly affects some very important design characteristics, such as routability, via usage and timing performance. Crosstalk, which is largely decided by wire adjacency, has significant impact on interconnect delay and circuit performance. Therefore, the amount of crosstalk should be restrained in order to satisfy timing constraints. In this work, a track assignment approach is proposed to control crosstalk-induced performance degradation. The problem is formulated as a Traveling Salesman Problem (TSP) and solved by a graph-based heuristic. The proposed approach is implemented and tested on benchmark circuits from the ISPD2011 contest and the experimental results are quite promising.
