Logic built-in self-test (or LBIST) is a form of built-in self-test (BIST) in which hardware and/or software is built into integrated circuits allowing them to test their own operation, as opposed to reliance on external automated test equipment.
Voltage droop mitigation during automotive electronics built in self test
PCT designated stageWO2026117324A1Electrical testingGenerating/distributing signalsControl engineeringVoltage droop
Aspects of the disclosure are directed to variable shift frequency implementation. In accordance with one aspect, the disclosure includes synthesizing a divided clock (511) from a shift clock (501) with a divided frequency equal to a reference frequency divided by a selected integer divisor in a logical built-in self-test (LBIST) mode; transitioning the LBIST mode from a shift state to a capture state by enabling a capture control enable signal (502) while pacing with the divided clock (511); generating a stretched capture control enable signal from the capture control enable signal using a slow cycle programmer (SCP, 530) with a plurality of quad stage pipelines; and transitioning the LBIST mode from the capture state to a subsequent shift state with the stretched capture control enable signal in a HIGH state to mitigate voltage droop.
