Abstract
Techniques are disclosed relating to testing logic in integrated circuits based on power being received by the integrated circuit. In one embodiment, an integrated circuit includes a memory and a self-test unit. The self-test unit is configured to receive an indication that identifies a memory block as being in a low-power state and to determine whether to disregard test data read from the one or more memory banks. In some embodiments, the self-test unit may be configured to mask a portion of test result related to the test data that the self-test unit has determined to disregard. The self-test unit may include an error validation logic configured to determine a validity of test data received from a memory based on a power activation status (e.g., whether the memory is powered on or off) associated with the memory.
