Scan based at-speed testing has become mandatory in industry to detect delay defects today in order to maintain test quality and reduce test cost. However, the effects of power supply droop during test application often introduce timing uncertainty, such as clock stretch and additional gate delay. It leads to false failure and test escape during test and makes the application of the at-speed scan testing become a challenge task to screen out delay defects successfully. In this paper, we review existing studies about the power supply droop and the methods to reduce its impact on at-speed scan testing.
