Post placement optimization is a placement optimization that can potentially improve critical path timing at the expense of additional run time. The optimization is performed on a fully placed design with timing violations. For each of the top few critical paths, the placer tries moving critical cells to improve delay and commits new cell placements if they improve estimated delay. For designs with longer run times and relatively more critical paths, these placement passes might further improve timing.
