With the rapid development of integrated circuits,the circuit function is becoming more and more cmoplex,and the burn-in test is required monitoring as many signals as possible,therefore,the coverage and reliability of the burn-in test directly determine the screening quality of integrated circuits.This paper uses the example of the design of a signal monitoring system,to find a new way to monitor the signal,and gives some suggestions on the selection,in order to give some help to the aging engineers in burn-in.
