Abstract
A system-on-chip (SoC) includes multiple critical components and a testing system to test the critical components. The critical components include an intellectual property (IP) core and an associated logic circuit. The testing system includes a controller, a fault injector, and a masking circuit. The controller is configured to receive a test initiation request and generate first and second select instructions. The fault injector is configured to generate and inject a set of fault inputs in the logic circuit based on the first select instruction to test the associated logic circuit and the IP core. The IP core is configured to generate a set of responses that is associated with the testing of the logic circuit and the associated IP core. The masking circuit is configured to mask and output the set of responses when the second select instruction indicates a first value and a second value, respectively.
