Abstract

Scan chain reordering based on physical design informationhelps in reducing routing bottleneck and in minimizingdesign constraint violations. This paper proposesintegrating this capability into synthesis-based design reoptimization.It describes the benefits of such an approach, thedesign synthesis context, presents new ordering conceptsand concludes with results on real designs.
