Abstract
A method is provided that comprises a circuit design that includes multiple design blocks; a power intent specification file that defines a power domain within the circuit design and that identifies design instances within the power domain and that defines a control function to selectively transition the defined power domain between multiple respective power supply values; using a digital simulator to simulate operation of the digital representation while using an analog simulator to simulate operation of the analog representation; wherein simulating the digital representation includes transitioning the defined power domain between supply values from among the multiple respective supply values; wherein simulating the analog representation includes periodically storing in a storage location a power supply value currently in use during digital simulation of the digital representation; and wherein simulating the analog representation includes using the stored currently in use power supply value to supply voltage to the analog representation.
