SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

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).
