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.
Claims36
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.
A semiconductor integrated circuit comprising:
- an interconnect layer of the semiconductor integrated circuit between a substrate region of the semiconductor integrated circuit and an upper layer of the semiconductor integrated circuit;
- a main line in said upper layer, said main line extending along a first direction;
- branch lines in said interconnect layer, said branch lines extending along a second direction;
- a row of power supply switch cells in said substrate region, said row of the power supply switch cells extending along said first direction;
- a control line extending along said first direction, one of the power supply switch cells and a second one of the power supply switch cells being directly electrically connected to said control line.
A semiconductor integrated circuit, comprising:
- branch lines that extend in parallel along a first direction;
- a main line that extends along the first direction in parallel to the branch lines;
- an auxiliary interconnect that extends along a second direction so as to cross the branch lines and the main line;
- a contact that electrically connects a first one of the branch lines with the auxiliary interconnect;
- and
- a first switch cell that is electrically connected to the main line and the first one of the branch lines,
- wherein the first switch cell is controllable by a control signal to electrically disconnect the main line from the first one of the branch lines.
