Abstract
A semiconductor circuit includes a first circuit block, a second circuit block, and power wiring lines that supply a plurality of reference potentials. The first circuit block and the second circuit block are connected to a common power wiring line that is one of the power wiring lines and supplies a common reference potential. A width of the common power wiring line in the first circuit block is smaller than a width of the common power wiring line in the second circuit block.
