Abstract
A computer implemented method for designing a semiconductor integrated circuit includes placing dummy pattern on a second interconnection layer positioned just above the first power line based on a placement result of the first power line, the dummy pattern having a long axis parallel with a direction of the first power line; and electrically connecting the dummy pattern to the first power line, based on placement results of the first power line and the dummy pattern.
