DUMMY METAL LAYOUT EVALUATING DEVICE, DUMMY METAL LAYOUT EVALUATING METHOD AND DUMMY METAL LAYOUT EVALUATING PROGRAM

摘要

PROBLEM TO BE SOLVED: To evaluate a dummy metal layout while being staggered with respect to a laying direction of a wire object.SOLUTION: A dummy mesh information creation part 21 divides a group of dummy metal blocks that are arranged in a pattern regularly staggered with respect to a direction of a wire object into meshes so that each mesh has the same layout of dummy metal blocks. An overlap determination part 23 determines whether a dummy metal block within a dummy mesh overlaps with the wire object regarding to a plurality of dummy meshes obtained by the determination. A dummy information calculation part 25 calculates dummy information after any dummy metal block that is determined to be overlapped with the wire object is removed. An information integration part 26 integrates the dummy information with information of the wire object. An evaluation part 27 evaluates whether the dummy fill a circuit layout after insertion of the integrated dummy satisfies the design criteria.
