Abstract: A circuit block including standard cells (1) arranged therein is provided with switch cells (20) capable of switching between electrical connection and disconnection between power supply lines (3) extending in an X-direction and power supply straps (11) extending in a Y-direction. Each of the power supply straps (11) is provided with a single switch cell (20) arranged every M sets of power supply lines (3) (M is an integer of 3 or more). In the Y-direction, the switch cells (20) are arranged at different positions in the power supply straps (11) adjacent to each other, and are arranged at the same position every M power supply straps (11) in the X-direction.

Abstract: Power switch cells (20) respectively includes power switches (21), each of which is capable of performing switching between electrical connection and disconnection between a global power supply line (11) and a local power supply line (8) in accordance with a control signal (CTR). The power switches (21) are connected in a chain state to constitute a chain connection through which the control signal (CTR) is sequentially transmitted. A starting point switch (21a) in the chain connection has a greater distance to an edge (BE) of a region occupied by a power domain than an ending point switch (21b).
