CPRI v8.6 rev1 Patch

For a detailed list of CPRI Release Notes and Known Issues, see (Xilinx Answer 54473).

Patch Installation :

  1. Navigate to the $XILINX_VIVADO/patches directory (create this directory if it does not exist). (See (Xilinx Answer 60154) for steps to set your XILINX_VIVADO environment variable so that it points to your Xilinx installation).
  2. Extract the contents of the ".zip" archive to a directory there, and call the directory AR68300. Note: most extraction tools will allow you to automatically create a directory with the same name as the zip file.
  3. Run Vivado software tools from the original install location.

Fixed Issue:

  • 64B66B Control Word /T/ cannot be encoded correctly.
  • Issue when using RERXCLKOUT of the UltraScale GTH Channel, so it can be driven to OBUFDS_GT3/4. CPRI only provides a RERXCLKOUT port, you will need to instantiate OBUFDS_GT3/4 explicitly.
