Abstract
Disclosed herein is a semiconductor integrated circuit including: a cell layout region including circuit cells subject to power control the supply and interruption of power to which is controlled by a power switch, and always-on circuit cell groups which are always powered after the activation; a main line laid out in the cell layout region and applied with a source or reference voltage; and first and second branch lines which branch from the main line in the cell layout region.
Claims9
A semiconductor integrated circuit comprising:
- a main line in a main-line-adjacent region, the main line extending along a first direction;
- a first circuit in a first region, the main-line-adjacent region is between the first region and a second region;
- a second circuit electrically connected to the main line, the second circuit is in the main-line-adjacent region;
- a first branch line electrically connected to the main line, the first branch line extending along a second direction;
- a second branch line electrically connected to the first circuit, the second branch line extending along the second direction;
- and
- a power switch in the main-line-adjacent region, the power switch is controllable to provide electrical connection and disconnection between the first branch line and the second branch line,
- wherein the main line is in a main line wiring layer and the first branch line is in a branch line wiring layer, the branch line wiring layer is between the main line wiring layer and a circuit layer.
