Abstract
The resistance value of a supply line (Rline), the resistance value of a decoupling capacitor (Rcap), and the resistance value of a transistor (Rmos) are separately calculated from mask layout information of a semiconductor integrated circuit. The resistance value between external terminals (Ri) is calculated from the resistance value Rline, the resistance value Rcap, and the resistance value Rmos.
