Abstract:

This paper presents an incremental timing-driven placement tool, named OWARU. It optimizes timing critical paths through a free space-aware path smoothing: the gates on such paths are relocated to free spaces around the smoothed paths, while incremental static timing analysis is involved to accurately assess timing changes due to the relo...More
