Abstract
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.
Claims11
A semiconductor integrated circuit, comprising:
- a plurality of circuit cells;
- a main wiring line to which a power supply voltage or a reference voltage is applied, the main wiring line extending in one direction;
- a plurality of sub wiring lines disposed in a different direction perpendicular to the one direction and individually shared by predetermined ones of the plural circuit cells which are juxtaposed in the different direction;
- a plurality of power supply switch cells for controlling connection and disconnection between the 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.
