Abstract
A method of optimizing a power supply network is executed by a CAD system, and estimates current consumptions of component function blocks, then determining routes of power supply lines in such a manner as to pass through areas with local maximum values of the estimated current consumption, determining the entire route of the power supply network, finally regulating width of each power supply line incorporated in the power supply network on the basis of the amount of current passing therethrough so that the power supply network is free from electromigration.
