An integrated circuit (IC) device, such as a system on chip, includes a plurality of hardware circuitry components and a power delivery network to delivery power to the plurality of hardware circuitry elements. The power delivery network has a plurality of integrated switches and a corresponding data plane to couple the plurality of switches to a controller on the IC device. The controller sends signals on the control plane of the power delivery network to granularly select which of the plurality of hardware circuitry elements to power-gate and may do so at the direction of a software system.
