Abstract

Cells with the same logic and similar driving capability among cells arranged on a substrate of a semiconductor integrated circuit are made into a format comprising terminals at the same position in the same-sized cell frame, and within cells in such a format, by arranging other cells in a redundant region of cell frame in a cell with low driving capability, wiring modification operation is reduced in layout of a semiconductor integrated circuit and efficiency of circuit design is improved, preventing chip size from being redundantly large.
