If using SGMII with the fabric elastic buffer, Comma alignment attributes need to be updated:
(on page 3 of the GUI, select under SGMII Capabilities "10/100/1000 Mb/s" (clock tolerance compliant with Ethernet specification)):
If you are using VHDL, change the following in example_design\transceiver\gtxwizard_gt.vhd:
ALIGN_COMMA_WORD => (1),
CLK_COR_MAX_LAT => (9),
CLK_COR_MIN_LAT => (7),
ALIGN_COMMA_WORD => (2),
CLK_COR_MAX_LAT => (10),
CLK_COR_MIN_LAT => (8),
If you are using Verilog, change the following in example_design\transceiver\gtxwizard_gt.v:
.ALIGN_COMMA_WORD (1),
.CLK_COR_MAX_LAT (9),
.CLK_COR_MIN_LAT (7),
To:
.ALIGN_COMMA_WORD (2),
.CLK_COR_MAX_LAT (10),
.CLK_COR_MIN_LAT (8),
