  • Yield-oriented design-for-test in power-switchable cores
    Patent number: 10955472
    Abstract: An integrated circuit includes first and second cores. Each core has a power-switchable portion in a first power domain in which an operating power is turned on or off in response to a power control signal. The first power domain includes a first scan chain, and the first power domain also includes a plurality of outputs. Each core also includes an always-on portion in a second power domain in which the operating power is maintained during testing of the integrated circuit. The second power domain also has a second scan chain. The second power domain further includes respective isolation gates coupled to the plurality of outputs of the first power domain, and the second scan chain includes a respective wrapper cell coupled to some isolation gates. The integrated circuit is configured to power off and isolate the power-switchable portion in the first power domain based on a scan test result.
