As per GES errata (EN183 and EN192), OOB circuit is enabled by default in 7 series GTX transceivers. This errata has been fixed in production silicon. Since Aurora 8B10B does not use OOB circuit, the GTX settings provided in this answer record are required to power down the OOB circuit and to make sure the downstream circuits ignore the OOB detector outputs. Aurora 8B10B link initialization will not complete if these attributes are not set. This issue will not occur with Aurora 8B10B cores targeting 7 series GTX/GTH transceivers in GES silicon.
The attribute settings provided in this answer record should be used for Aurora 8B10B v8.1(ISE 14.1) through v8.3 (ISE 14.4, ISE14.3/Vivado 2012.3) cores targeting 7 series GTX/GTH transceivers in production silicon and Zynq (IES and later silicon) SoC GTX.
The following attribute settings should be used for Kintex-7 GTX and Virtex-7 GTX/GTH production silicon, Zynq (IES and later silicon) SoC GTX:
The above settings are available in v8.3Rev1 Aurora 8B10B core that was released in the Vivado 2012.4 tools.
