A standard cell is split into a plurality of regions, and shareability information having pin information is added to a cell library for each of the split regions. Through comparison of shareability information, a determination is made as to whether, at the time of automatic placement, a standard cell can be placed so as to share part of its region with a standard cell placed adjacent to that standard cell. On the basis of the determination result, when placing a standard cell, a standard cell to be placed adjacent to that standard cell is placed so as to share part of its region, thereby making it possible to reduce the placement area. |
