Provided are a differential signal inversion correction circuit and a method therefor, the structure thereof comprising: a data frame sending module structure for, when detecting the status of a link, generating a specific logic sequence, and completing the sending of same through input/output ports, so that a receiving end receives the sequence for performing processing and analysis to realize the judgement of the transmission status of the link, wherein a receiving end comparator receives sequence data for performing corresponding comparison, checking and feedback control, thereby achieving the purposes of link detection and differential correction; and an inversion control signal generation module for receiving the comparison result of the comparator, generating a corresponding control signal and controlling whether the link executes an inversion operation. Compared with the prior art, the differential signal inversion correction circuit and the method therefor realize the detection and control of differential inversion of a high-speed differential link, and at the same time are applicable to multichannel parallel detection and correction, can effectively improve logic design verification efficiency, and reduce the hardware debugging complexity. |
