Abstract:
A test circuit is operable in ATPG mode and LBIST mode. The test circuit includes a clock selection circuit. The clock selection circuit includes clock logic circuitry to receive an LBIST mode signal and an ATPG mode signal and to generate an indication of whether the test circuit is operating in either the ATPG mode or the LBIST mode, a multiplexing circuit to receive an ATPG clock and a functional clock as input and output a selected one of the ATPG clock and the functional clock, and a clock gate circuit enabled in response to enable signals. The enable signals are an inverse of a selected one of the ATPG clock and the functional clock. The clock gate circuit receives the indication of whether the test circuit is operating in either the ATPG mode or the LBIST mode and generates a test clock as a function of the indication.

Claim (Index 11):
The test circuit of  claim 10 , wherein the first circuit comprises:\n a first circuit first OR gate configured to receive a stuck-at ATPG signal, a scan enable signal and a shift clock pass signal and generate a first OR output; a third clock gate circuit having a third clock gate data input configured to receive the first OR output and a third clock gate enable input configured to receive the shift clock, the third clock gate circuit configured to generate a third clock gate output; a fourth clock gate circuit having a fourth clock gate data input configured to receive an inverse of the first OR output and a fourth clock gate enable input configured to receive the PLL clock, the fourth clock gate circuit configured to generate a fourth clock gate output; and a first circuit second OR gate configured to receive the third and fourth clock gate outputs and generate an output to a first clock gate circuit enable input of the first clock gate circuit.
