PROBLEM TO BE SOLVED: To minimize the number of changed masks in a circuit change after the masks are formed. SOLUTION: When at least any changes of a logic element and a wiring generate after the masks are formed, based on circuit change information and layout information before the circuit change, arrangement coordinates or wiring coordinates of the logic element in which the changed logic element or wiring can be wired by a designated wiring layer are retrieved. The arrangement or wiring of the logic element is conducted based on the retrieved coordinates information. COPYRIGHT: (C)2009,JPO&INPIT
