ABSTRACT:
A power supply system of a semiconductor integrated circuit device is broken down into an outer power supply sub-system associated with an outside function block and an inner power supply sub-system associated with an inside function block, and is implemented by more than three loop wirings extending between the outside function block and the inside function block, wherein first conductive blocks and second conductive blocks are selectively coupled with the more than three loop wirings for providing the outer and inner power supply sub-systems so that impedances of the outer and inner power supply sub-systems are optimized by changing the numbers of the loop wirings.
