Semiconductor integrated circuit

摘要

A semiconductor integrated circuit includes: a main-interconnect to which supply voltage or reference voltage is applied; a plurality of sub-interconnects; a plurality of circuit cells configured to be connected to the plurality of sub-interconnects; a power supply switch cell configured to control, in accordance with an input control signal, connection and disconnection between the main-interconnect and the sub-interconnect to which a predetermined one of the circuit cells is connected, of the plurality of sub-interconnects; and an auxiliary interconnect configured to connect the plurality of sub-interconnects to each other.

主权项

1. A semiconductor integrated circuit, comprising:
a plurality of circuit cells; a plurality of sub wiring lines disposed in a first direction and individually shared by predetermined ones of the plural circuit cells, a plurality of the predetermined ones of the plural circuit cells being juxtaposed in the first direction; a plurality of power supply switch cells for controlling connection and disconnection between individual sub wiring lines and said main wiring line in response to a control signal inputted thereto; and an auxiliary wiring line for connecting the plural sub wiring lines to each other, the auxiliary wiring line extending in a second direction that is perpendicular to the first direction, wherein the predetermined ones of the plural circuit cells include a first circuit cell that is located at a left side of one of the sub wiring lines and a second circuit cell that is located at a right side of said one of the sub wiring lines.
