Jitter injection method, device and storage medium

Abstract

The present invention provides a jitter injection method, device and storage medium, wherein the jitter injection method includes obtaining a target jitter injection strategy set in a candidate jitter injection strategy set; based on each target jitter injection strategy in the target jitter injection strategy set, obtain Target jitter set; according to the jitter frequency range, each target jitter in the target jitter set is injected into the jitter adjustment circuit in a multi-channel form to obtain a reference clock frequency; according to the reference clock frequency, a high-speed code stream is generated; the high-speed code stream is input to the target circuit, so that the target circuit can use the high-speed code stream to perform the jitter tolerance test. By adopting the method, the purpose of improving the precision of jitter injection can be achieved.

Description

technical field [0001] The present invention relates to the technical field of integrated circuits, in particular to a jitter injection method, device and storage medium. Background technique [0002] With the development of integrated circuit technology, its application has spread in almost all fields. Integrated circuits have to undergo various tests before they leave the factory or are officially put into use. One of the important tests is the jitter tolerance test. By injecting jitter into the integrated circuit, it can Judging the tolerance of the integrated circuit to jitter, so as to determine the performance of the integrated circuit. [0003] The jitter injection method in the prior art is generally implemented in the form of a delay line. Since the noise floor level of the delay line is poor, the jitter injection method using the delay line will also deteriorate the quality of the output signal without adding jitter. The problem of low accuracy of jitter injection...
