Patent ID: 7786566

Claim:
A semiconductor integrated circuit, comprising: a macro cell having a plurality of circuit elements; a first macro cell power supply line for supplying a first potential to the macro cell, the first macro cell power supply line having a longer side extending in a first direction, a shorter side shorter than the longer side, and two end portions; and a second macro cell power supply line, formed in a same wiring layer as a wiring layer of the first macro cell power supply line, for supplying a second potential to the macro cell, the second macro cell power supply line having a longer side extending in the first direction, a shorter side shorter than the longer side of the second macro cell power supply line and two end portions, wherein: the first and second macro cell power supply lines are provided on the macro cell, and the first macro cell power supply line and the second macro cell power supply line are disposed on a same straight line in the first direction so that the two end portions of the first macro cell power supply line and two end portions of the second macro cell power supply line are disposed on the same straight line.
