Abstract:
1. A structure of a power supply path utilized in the design of an integrated circuit, wherein in every cell in the integrated circuit, a power supply path on a power supply side of a high potential and a power supply path on a power supply side of a low potential are provided opposite each other, and wherein in every cell in the integrated circuit, the power supply path on the power supply side of the high potential and the power supply path on the power supply side of the low potential each comprise: a main power line; and a plurality of outgoing power lines branching off from the main power line, wherein a plurality of pitches between adjacent outgoing power lines of the plurality of branched outgoing lines in the longitudinal direction of the main line are set so as to be equal to each other, and the pitch between the main power line of the power supply path on the power supply side of the high potential and the main power line of the power supply path on the power supply side of the low potential is set to be longer than the sum of the length of an outgoing line of the power supply side of the high potential and the length of an outgoing line of the power supply side of the low potential provided oppositely to said outgoing line of the power supply side of the high potential.
