This paper presents a novel placement algorithm for timing optimization based on a new and powerful concept, which we term differential timing analysis. Recognizing that accurate optimization requires timing information from a signoff static timing analyzer, we propose an incremental placement algorithm that uses timing information from a signoff static(More)
This paper presents a new timing driven force directed placement algorithm that meets physical net length constraints as well as constraints on specific pin sets. It is the first force directed placement algorithm that meets precise half perimeter bounding box constraints on critical nets. It builds on the work of Eisenmann et al. [12], adding a new net(More)
This paper describes a new force directed global placement algorithm that exploits and extends techniques from two leading placers, Force-directed [12] [26] and Mongrel [22]. It combines the strengths of force directed global placement with Mongrel's cell congestion removal to significantly improve the quality of placement during the difficult overlap(More)
