Abstract
A method for evaluating performance of a sequential logic element includes: inputting a preset clock signal and a data signal to a sequential logic element to be tested; decrementing a setup time of the sequential logic element from a first preset value to a second preset value based on a preset decrement step, where the first preset value is determined by a setup time when the sequential logic element to be tested outputs a target sampled value, and the second preset value is determined by a setup time when the sequential logic element outputs a reverse value of the target sampled value; and determining an evaluation parameter of the sequential logic element based on a sampled value output by the sequential logic element after each decrement of the setup time, and evaluating performance of the sequential logic element based on the evaluation parameter of the sequential logic element to be tested.
