Fast floorplanning by look-ahead enabled recursive bipartitioning
2005
Proceedings of the 2005 conference on Asia South Pacific design automation - ASP-DAC '05
A new paradigm is introduced for floorplanning any combination of fixed-shape and variable-shape blocks under tight fixedoutline area constraints and a wirelength objective. Dramatic improvement over traditional floorplanning methods is achieved by explicit construction of strictly legal layouts for every partition block at every level of a cutsize-driven, top-down hierarchy. By scalably incorporating legalization into the hierarchical flow, post-hoc legalization is successfully eliminated. For
