US Patent 8928351 Emulating power domains in an integrated circuit using partial reconfiguration

Testing power domains of a circuit design includes correlating, using a processor, a selected power domain of a circuit design having a plurality of power domains with a partial reconfiguration partition and implementing the circuit design within an integrated circuit. The partial reconfiguration partition is implemented within a reconfigurable region of the integrated circuit. A power off state for the selected power domain of the circuit design is emulated by partially reconfiguring the reconfigurable region of the integrated circuit.
