Abstract
A delay measurement circuit includes: a loop flag generation circuit configured to: generate a loop flag signal and input the loop flag signal to the loop of the delay-locked loop when loop delay measurement is performed on the delay-locked loop; and generate a measurement finish signal and generate a target pulse signal after the loop flag signal is cycled for M times in the loop of the delay-locked loop, a valid pulse width of the target pulse signal being equal to M times a loop delay; and a counter circuit configured to: receive a divided clock signal; time the valid pulse width of the target pulse signal based on the divided clock signal, to obtain a timing result; and perform preset processing on the timing result, to obtain a loop delay measurement result of the delay-locked loop.
