With a conventional method for designing cell layout, it is necessary to give relative positional information in advance to all cells to be arranged. Furthermore, the conventional method is troublesome because it is necessary to correct relative positional information of cells after confirming a result of temporary layout. Therefore, it takes time to obtain a layout result. To avoid these problems, cells of a specific type specified from outside, or cells satisfying specific conditions, are extracted and arranged first or limited to a layout position by specifying a layout position, then arranging the remaining cells using a general layout algorithm.
