This paper describes the implementation of a wire length-driven force-directed placer named FDP for generic placement. Specifically, it describes efficient force computation for cell spreading, numerical instabilities during force-directed placement, a means to avoid instabilities, and metrics for proper assessment of cell distribution throughout the placement region. It demonstrates that one of the greatest impediments to achieving high-quality placements using a force-directed placer lies in… CONTINUE READING
