    CR# 603961

Known Issues

The following items are known issues for v6.1 of this core at time of release:

  • Virtex-7/Kintex-7 supports simulation only
    Description: For Virtex-7/Kintex-7 the core supports simulation only
  • Virtex-6 HXT/GTH selection of quads should be consecutive
    Description: In Virtex-6 HXT/GTH, for line rates >9.8G the quad selection should be consecutive. There cannot be a unused quad between two used quads
  • Virtex-6 HXT/GTH solutions are pending for hardware validation
    Description: Virtex-6 GTH designs are not validated on hardware
  • Virtex-6 HXT/GTH ES/PS attribiute settings
    Description: Refer to Aurora 64B66B v5.1 for ES settings for GTH transceivers
    Refer to Aurora 64B66B v6.1 for PS settings for GTH transceivers
  • QVirtex-6L devices are not supported
    Description: Core is not enabled when QVirtex6L devices are selected
  • Core does not generate for 0.5G line rate for Virtex-7/Kintex-7 devices
    Description: When Virtex-7/Kintex-7 device is targeted for 0.5G as line rate, the core errors on generation
