摘要
We consider the problem of selecting a realization for each of the blocks in a floorplan so that the area of the floorplan is minimized. We propose doing this by repeatedly replacing primitive superblocks by equivalent basic blocks. linear time algorithm to determine all the needed primitive superblocks is developed. Equivalent basic blocks are found by using Stockmeyer's algorithm if the primitive superblock has slicing structure and by using branch-and-bound if not. Experimental results are also provided.
