  • Techniques and circuits for testing a virtual power supply at an integrated circuit device
    Patent number: 9891271
    Abstract: A power grid provides power to one or more modules of an integrated circuit device via a virtual power supply signal. A test module is configured to respond to assertion of a test signal so that, when the power grid is working properly and is not power gated, an output of the test module matches the virtual power supply. When the power grid is not working properly, the output of the test module is a fixed logic signal that does not vary based on the power gated state of the one or more modules.
