Versal device GTY and GTM transceivers support an Integrated Bit Error Ratio Tester (IBERT) which enables in-system serial I/O validation and debug. This allows the measuring and optimization of high-speed serial I/O links.
IBERT should be used when you are interested in measuring the quality of a signal after receiver equalization has been applied to the received signal.
Unlike previous architectures, the Versal device IBERT functionality is integrated into the GTY and GTM transceivers and requires only a design which uses the transceivers. For more information on IBERT functionality, see this link in the Versal Adaptive SoC Transceivers Wizard LogiCORE IP Product Guide (PG331).
