Title: PROCESS DEVIATION DETECTION CIRCUIT AND METHOD, AND COMPUTER STORAGE MEDIUM
Abstract:
Disclosed is a process deviation detection circuit and method. The circuit comprises: a first transmission path (110) for receiving and transmitting a first enable signal and outputting a first transmission signal; a second transmission path (120) for receiving and transmitting the first enable signal and outputting a second transmission signal; and a detection unit (130) for detecting the process deviation on the basis of the transmission delay of the first transmission signal and the second transmission signal; and the process deviation sensitivity of the first transmission path is a first sensitivity, while the process deviation sensitivity of the second transmission path is a second sensitivity. With the above circuit, a signal representing the process deviation can be easily detected, and the process deviation can be precisely and easily detected.
