The following answer record contains a tactical patch with updates and fixes for the 2019.1.3 release of Vivado for the UltraScale+ GTM Transceivers Wizard (gtm_wizard_ultrascale_v1_0) and UltraScale+ GTM IBERT (ibert_ultrascale_gtm_v1_0) IP cores.
Caution: Both IP cores and each of the Example design files will need to be regenerated with this patch.
To apply this tactical patch:
The following port additions are included in this tactical patch:
Ports for Temperature sensing, applicable per GTM Wizard IP instance:
The GTM Wizard and GTM IBERT IP integrate the SYSMON instantiation in the example design. Users designing with example designs do not need custom connections to temperature[9:0] ports.
For GTM parent IP designs that do not include SYSMON instantiations in this patch release, users can manually edit and tie off these ports to 0.
However, designs using PAM4 modulation with either 1) less than 12dB insertion loss at Nyquist or 2) line rate greater than 53Gb/s must integrate the SYSMON instantiation and provide valid values to the temperature[9:0] ports.
Ports when Transcoding configurations are enabled in GTM Wizard GUI:
Ports for each GTM_DUAL selected in GTM Wizard GUI:
GTM Controller utilizes the Integrated KP4 RS-FEC for designs with PAM4 modulation and insertion loss of less than 12dB (as set in GTM Wizard Receiver Advanced Options).
The GTM wizard example design makes these port connections. No additional connections are needed.
Designs that do not utilize the integrated KP4 RS-FEC for the specified use mode must implement their own KP4 RS-FEC IP to provide equivalent statistic information as described in the RX FEC section in the Virtex UltraScale+ FPGAs GTM Transceivers User Guide (UG581):

Ports for Sampled Eye Scan:
Sampled Eye Scan ports were included in the general Vivado 2019.1.3 release.
For more details, see (Xilinx Answer 72110) - UltraScale+ GTM - Does GTM support Manual EyeScan like GTY and GTH do?
Known issues for this patch:
Setting the Insertion Loss to < 12 dB in the IBERT UltraScale+ GTM IP Wizards Advanced Settings tab causes the IBERT GTM Eye Slicer Plots to fail to display in the Vivado Hardware Manager GUI.
The IBERT GTM Eye Slicer Plots work as expected when the Insertion Loss is set to >= 12 dB. This issue will be resolved in the upcoming 2019.2 release.
Issues not covered by this patch:
