Abstract
A method of designing a semiconductor integrated circuit makes it possible to reduce the amount of manual routing of a power wire. After a V power wire for a circuit block and a V power wire for the circuit block have been routed, the number and positions of y-direction V power wires are determined from consideration of the positions thereof. A first y-direction V power wire among the y-direction V power wires is used without being in contact with edges of the V power wire for the circuit block, but it overlays the routing position thereof. For that reason, non-selection of that first y-direction V power wire is determined. The other y-direction V power wires are subsequently routed automatically.
