Semiconductor integrated circuit

A semiconductor integrated circuit comprising:

• a switch circuit that includes switches of different types each having a different allowable current, and that is configured to supply voltage to at least one circuit connected to the switches respectively;
• and
• a control circuit configured to switch to the on state the switches of a first type having a first allowable current and then the switches of a second type having a second allowable current larger than the first allowable current, wherein two or more of the switches of the same type are simultaneously switched to the on state, according to a parameter.

A semiconductor integrated circuit comprising:

• a switch circuit provided between a power supply circuit and a circuit domain to which a power supply voltage is to be supplied, wherein the switch circuit includes a plurality of first switch circuits allowing a first current to flow and a plurality of second switch circuits allowing a second current larger than the first current to flow, wherein each of the first switch circuits and the second switch circuits is configured to switch between an on state of supplying voltage to a respective one of a plurality of circuits connected thereto and an off state of cutting off the voltage supplied to the respective one of the plurality of circuits connected thereto;
• and
• a control circuit configured to switch to the on state the first switch circuits and then the second switch circuits, wherein two or more of the first switch circuits or two or more of the second switch circuits are simultaneously switched to the on state according to a parameter.
