ABSTRACT:
Elements such as a transistor having a terminal corresponding to a wire junction are abstracted by using rectangles, and a spit penetrating these rectangles is introduced in a layout area where the rectangles are disposed. On the spit, a wire junction for allocating a wire is provided. The terminals of the rectangles corresponding to the wire junctions and the wire junctions on the spit are set as net targets, and connection information on these net targets is generated. A scan line for scanning the layout area from its left end to its right end and a front for tracing the net targets are introduced. While conducting rightward scanning by the scan line, the front is proceeded from one net target to the other net target. The trace of the front is provided as a wire element.
