RXAUI v2.4 - Updates maybe needed to the 7 Series GT Transceiver wrapper files


RXAUI v2.4 uses the 7 Series FPGAs Transceiver Wizard v2.3. This targets GES and Production GTX silicon, GES GTH silicon, and IES GTP silicon.

If using Artix-7 GTP or Virtex-7 GTH transceivers, there were some 7 series FPGAs Transceiver Wizard v2.3 changes that did not make it into the wrappers file. This does not apply to devices using 7 series FPGA GTX Transceivers.


If using Virtex-7 GES GTH transceivers:

When using both Dune Networks and Marvell modes, the following attribute update is needed in the example_design/core_name_gt_wrapper_gt..v/vhd.

For VHDL change RXCDR_CFG to:

RXCDR_CFG => (x"0002007FE2000C2080018"),

For Verilog change RXCDR_CFG to:

.RXCDR_CFG (83'h0002007FE2000C2080018),

If using the Artix-7 GTP transceivers:

If using the Dune Networks Mode, the 7 Series FPGAs Transceiver Wizard can be regenerated using the RXAUI - Dune Networks Template. The component name used when generating should be rxaui_core_name_gt_wrapper. The core_name_gt_wrapper.v/vhd and core_name_gt_wrapper_gt.v/vhd should be replaced with the new files generated by the 7 Series FPGAs Transceiver Wizard.

If using Marvell mode, open a Xilinx WebCase to get assistance with updating the Artix-7 GTP wrapper files.
