<P>PROBLEM TO BE SOLVED: To easily achieve a power supply wiring layout of a semiconductor integrated circuit in a short period, and to design the semiconductor integrated circuit with high durability. Ž<P>SOLUTION: In a design support device, an acquisition part 401 acquires power supply wiring layout information 100 wherein a standard cell is not arranged, and a detection part 402 detects a via missing part. Next, an extraction part 403 extracts a cross point on a power supply wiring line of a bottommost layer from the power supply wiring layout information 100. A first search part 404 searches for a power supply wiring route to the cross point on the bottommost layer wiring line from a power supply pad, wherein a resistance value becomes minimum not through the via missing part. A second search part 405 searches for a power supply wiring route through the via missing part based on the resistance value of the power supply wiring route searched for by the first search part 404. An output part 406 outputs search results obtained by the search by the first and second search parts. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
