Because the GTM receiver is ADC-based, the conventional eyescan as used in the previous families of transceivers (such as GTH or GTY transceivers) cannot be used. For this reason, the IBERT dashboard for GTM shows three plots: Slicer-Eye, Histogram, and Signal to Noise Ratio (SNR) instead of the traditional Scan Plot Window.

Once a link is created, the Slicer-Eye, Histogram, and Signal to Noise Ratio (SNR) plots are displayed for the link. If you created multiple links, the active link can be changed by selecting the desired DUAL and Channel in the upper-right corner.

For more information on the Slicer-Eye and GTM Transceiver Architecture see the Virtex UltraScale+ FPGAs GTM Transceivers User Guide (UG581).
