摘要：
A floorplanning apparatus includes a seed position decision section for deciding a placement position of a logic seed of each hierarchical block; a cell placement section for placing cells belonging to the hierarchical block around the placement position of each logic seed; and a placement region decision section for deciding placement and routing regions of each hierarchical block considering cell placement results produced by the cell placement section.
