PROBLEM TO BE SOLVED: To reduce power consumption while maintaining timing of an order cell to which timing driven arrangement is performed. SOLUTION: First, initial information is acquired (S1801). Next, the predetermined number of ROW area candidates are set in a cell arrangeable area in which the timing driven arrangement of the order cell is performed (S1802). Then, ranking processing is executed (S1803) to put priority of the ROW area candidates ri. After this, the number N of required ROW areas to be actually used for a chip is calculated (S1803). A ROW area is determined from among the ROW area candidates (S1805). Then, alignment processing of the order cell is executed (S1806). COPYRIGHT: (C)2011,JPO&INPIT
