New Features

  • ISE 13.2 software support
  • Auto Upgrade Support has been added. Older versions of the core- 1.4, 1.5, 16, 1.7, 1.8,1.9 can be upgraded to 1.10
  • Added support for 3G-SDI protocol template

Supported Devices

The following device families are supported by the core for this release:

  • Virtex-6 XC CXT/LXT/SXT/HXT
  • Virtex-6 XQ LXT/SXT   
  • Virtex-6 -1L XC LXT/SXT

Resolved Issues

  • CR 608107 - Until v1.9 version of the core, 8b/10b can only be selected as encoding when a data path width of 10, 20 or 40 is selected. This has been modified to 8, 16 or 32.
  • CR 596296 - Added support to bring GTXTEST[1] to wrapper input when requested.
  • CR 596294 - Updated logic not to provide RX_RESET after double_reset_pulse if RX Clock Source is from RXRECCLK.
  • CR 591651 - Updated TCL such that summary page shows correct line rate.

Known Issues

The following are known issues for v1.10 of this core at time of release:

  • Delay Aligner in both TX and RX is bypassed. For the clocking use models, and detailed information please refer to AR 39430.
  • Support for Virtex-6Q Lower Power devices are not present in Virtex-6 GTX Wizard. When a user attempts to generate a core with any of the qvirtex6l device packages and run implementation, it fails in MAP stage as the refclk pin locations in UCF are not correctly generated by the core. Please refer to answer records for detailed work-around.
