Abstract:
1. A cell including two or more wiring layers and being a component of a semiconductor integrated circuit as a functional unit registered in a cell library used by an automated design tool, the cell comprising: one or more transistors formed on a semiconductor substrate; a pair of intracellular power supply lines for supplying a power supply voltage and a ground voltage to the one or more transistors; and a plurality of connection terminals for inputting or outputting a signal of a circuit formed by the one or more transistors, wherein at least one power supply line passing region is provided in one of the wiring layers in which the intracellular power supply lines are not provided so that an intercellular power supply line having a width larger than those of the intracellular power supply lines can pass through the at least one power supply line passing region, wherein the power supply line passing region is provided between the plurality of connection terminals, and wherein the entire portion of the connection terminal is formed in the same wiring layer as the at least one power supply line passing region.
