AR# 47690

LogiCORE IP XAUI v10.3 - VHDL wrappers need update to RXCDR_CFG attribute for 7 series GTX Transceiver

Description

If targeting 7 series GTX Transceivers, the RXCDR_CFG setting needs to be updated in the VHDL wrapper files to the latest recommended value, see (Xilinx Answer 45360). This is not an issue for the Verilog wrapper files which already contain the update.

For XAUI Release Notes and Known Issues, see (Xilinx Answer 47684).

Solution

In the example_design/<core_name>_gt_wrapper_gt.vhd file, change RXCDR_CFG;

From:

RXCDR_CFG => (x"0b000023ff20400020"),
To:
RXCDR_CFG => (x"03000023ff40200020"),
