The ISPD global routing benchmark suite

Abstract

This paper describes the ISPD global routing benchmark suite and related contests. Total 16 global routing benchmarks are produced from the ISPD placement contest benchmark suite using a variety of publicly available academic placement tools. The representative characteristics of the ISPD global routing benchmark suite include multiple metal layers with layer assignment requirement, wire and via width/space modeling, and macro porosity modeling. The benchmarks have routable nets from 200 thousand 1.6 million. While primarily intended for global routing, they can be certainly extended for detailed routing or routing congestion estimation. In conjunction with the previous ISPD placement contest benchmark suite, the new global routing benchmarks will present realistic and challenging physical design problems of modern complex IC designs
