Abstract: A mechanism is provided for an integrated circuit with power gating. A power switch is configured to connect and disconnect circuits to a common voltage source. A capacitor tank is configured to supply wakeup charge to a given circuit. A controllable element is connected to the given circuit and to the capacitor tank. The controllable element is configured to controllably connect and disconnect the capacitor tank to the given circuit in order to supply the wakeup charge to the given circuit. The controllable element is configured to, responsive to the power switch disconnecting the given circuit from the common voltage source and to the given circuit being turned on to wakeup, supply the wakeup charge to the given circuit being turned on by transferring the wakeup charge from the capacitor tank to the given circuit. This reduces the electrical charge transferred from the circuits connected to the common voltage source.

Abstract: A method for generating a power model for a device includes identifying a device-level set of power contributors for a given state of the device, wherein each power contributor in the device-level set of power contributors contributes to power dissipation when the device is in the given state, and generating the power model for the device based on the device-level set of power contributors, wherein the power model is independent of process, voltage, and temperature.
