DESIGN METHOD, DESIGN PROGRAM AND DESIGN SUPPORT DEVICE FOR SEMICONDUCTOR INTEGRATED CIRCUIT, AND SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To shorten the design TAT of a semiconductor integrated circuit. SOLUTION: The design method of a semiconductor integrated circuit includes: a step of calculating consumption current amounts 211 of layout target circuits 41 and 42 based on circuit information 21; a step of calculating suppliable current amounts 212 per unit area in a region where a power can be supplied from a power wiring line 2; and a step of setting a cell size 213 of the layout target circuit based on the calculated consumption current amounts 211 so that consumption current amounts per unit area of the layout target circuits 41 and 42 are larger than the suppliable current amounts 212.
