Solution

This is a known issue that occurs when a users tries to implement the multi-link configuration of the UHD-SDI GT Core.

This issue has been fixed in Vivado 2018.2 and later.

  • Vivado 2018.1 - Users can download the UHD-SDI GT patch from (Xilinx Answer 70974) to work around this issue.
  • Vivado 2018.2 - This issue is resolved in the UHD-SDI GT IP in Vivado 2018.2 and later.

Note: For an existing design, the output products of the IP need to be reset after applying the patch.
