Abstract
A design method for a semiconductor integrated circuit, includes: a first calculating step; a second calculating step; and a setting step. The first step is a step of calculating a consumption current amount of a layout target circuit based on circuit information. The second calculating step is a step of calculating a suppliable current amount per unit area in a region where a power can be supplied from a power wiring line. The setting step is a step of setting a cell size of the layout target circuit based on the consumption current amount so that a consumption current amount per unit area of the layout target circuit is smaller than the suppliable current amount per unit area.
