Abstract
In a layout process of a semiconductor integrated circuit, a power supply is initially formed in an arrangement in which the current threshold value is not exceeded. In a case where the excess over the current threshold value occurs after the power supply is formed, the power supply arrangement is changed according to the current threshold value, design rule data base, and power supply wiring density so as not to exceed the current threshold value.
