Abstract
A semiconductor integrated circuit device includes a plurality of functional blocks each executing respective logic operations and arranged in an internal area on a semiconductor chip, and a first power source line arranged so as to surround the internal area. The first power source line is a closed-loop line. Second power source lines are provided for the respective functional blocks so as to surround the respective functional blocks on the chip. Each of the second power source lines is a closed-loop line. Third power source lines mutually connect the second power source lines for the functional blocks and connect the second power source lines and the first power source line.
