Classification: CPC G | IPC G

Claim 9:
10. The circuit of claim 9,
wherein the signature control circuitry is configured to
receive test outcome signals from the at least one circuit under test in response to the test stimulus signals being applied thereto,
produce signature comparison signals from the test outcome signals received from the at least one circuit under test,
compare in the set of signature control modules the signature comparison signals produced from the test outcome signals received from the at least one circuit under test with respective signature reference signals in the set of input signature registers, and
produce error signals in response to the signature comparison signals produced from the test outcome signals received from the at least one circuit under test failing to match with respective signature reference signals in the set of input signature registers.
