Research on Floorplanning

C.K. Cheng

Abstract

We discuss our recent progress of block placement for floorplanning. We first extended zone refinement to cluster refinement. We then devised an O-tree floorplan representation for efficient and effective flooplan operations. Lately, we explored the relations between floorplan representations, i.e. slicing O-tree, sequence pairs, corner block list, O-tree, and twin binary trees.
