SEMICONDUCTOR INTEGRATED CIRCUIT DESIGN METHOD, SEMICONDUCTOR INTEGRATED CIRCUIT DESIGN PROGRAM AND SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce the area of a semiconductor integrated circuit in a semiconductor integrated circuit design method, a semiconductor integrated circuit design program, and a semiconductor integrated circuit with a layout determined thereby. SOLUTION: In S104 of Fig. 1, each signal line is disposed in a signal wiring position having a predetermined positional relation with any one of wiring grids. In S102, layout of signal lines is determined so that when a signal line is disposed in a signal wiring position closest to a power supply line of signal wiring positions located outside the power supply line, the distance between this signal line and this power supply line is a predetermined shortest distance D to be ensured between signal line and power supply line or more, and the distance between mutually adjacent power supply lines corresponds to an added length of a double-length of D and an integral multiple of an added length of a predetermined shortest distance to be ensured between signal lines and the respective signal line widths.
