7 Series FPGAs Transceiver Wizard v2.5 - Known Issues and Release Notes


This answer record contains the Known Issues and Release Notes for the 7 series FPGAs Transceiver Wizard v2.5, released with the ISE 14.5 and Vivado 2013.1 design tools.


  * Version 2.5 
  * Native Vivado release
  * Support for Production Silicon for GTH and GTP.
  * New Protocol Templates added for GTH - SRIO multi lane, JESD204
  * New Protocol Templates added for GTP - JESD204

  • For GTH and GTP, the Wizard generates settings compatible for Production Silicon. Hardware validation of these settings is work in progress.
  • The Wizard generates Verilog wrappers for GTZ. VHDL is not supported.
  • Simulators supported for GTZ designs IUS and VCS.
  • For GTZ designs, the Wizard supports line rates and reference clocks shown in the GUI. No other values are tested or validated in hardware.
  • It is recommended that the Beachfront module generated for GTZ designs should NOT be modified by the user. Any edits made by the user might lead to unexpected results.
  • Please note that Vivado flow should be used for implementation of all SSIT devices.
  • Please note that the protocol templates provided by the Wizard are not characterized on hardware.
  • To simulate GTH and GTP Wrappers, the SIM_RESET_SPEEDUP parameter on the GT primitive should be set to false.
  • GTX Transceiver Wrappers generated for PCIE Gen2 protocol in VHDL have a known issue in functional simulation which is currently under investigation.
  • Post implementation functional and timing simulations are not supported for Transceiver wrappers generated for PCIE Gen1/Gen2 protocols.
