Abstract: An integrated circuit device includes a first module disposed within a first power domain, a second module disposed in a second power domain that is a sub-domain of the first power domain, first power gating logic, and second power gating logic. The first power gating logic generates a first virtual power supply for the first module. The second power gating logic is powered by the first virtual power supply for generating a second virtual power supply for the second power domain.
