Abstract

A method of switching a power supply of at least one voltage domain of a semiconductor circuit uses at least one microswitch, which is designed in standard cell design, to switch the power supply, so that the standard cell design method can be automated. Multiple microswitches can be disposed, evenly distributed, over those areas of the semiconductor circuit in which there is a voltage domain of which the power supply is to be switched. The microswitches of a voltage domain are defined by being switched by the same control signal. A semiconductor circuit to switch the power supply of the voltage domain includes microswitches, which can be constructed as transistors.
