5. KNOWN ISSUES AND LIMITATIONS

  - This version of the Wizard is NOT native Vivado compatible. Hence Upgrade from earlier versions of the IP is not supported in Vivado. To upgrade from v1.5, v1.6 or v2.1 versions, users can use the Generator tool.
  - Timing Simulation is not supported for Artix-7 FPGA
  - A GTP wrapper cannot be implemented on Hardware due to the issue given in CR 665415
  - Some GTP designs will error out with the message: [Drc 23-20] Rule violation (RTSTAT-6) Partial conflict due to the issue given in CR 667140
  - Simulation failure seen for GTX case when Internal Sequence Counter is used for 64B66B gearbox. The CR # is 668646
  - Implementation of PCI Gen1/Gen2 wrappers generated for GTP transceivers is not supported
  - The Wizard generates Verilog wrappers for GTZ. VHDL is not supported.
  - 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.
  - Known issues seen during implementation of GTZ designs generated using Start from Scratch template are captured in CRs 668228 and 668293
  - 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.

  - For information on GTH Initial ES Settings, refer to (Xilinx Answer 47128).
  - For information on GTX General ES Settings, refer to (Xilinx Answer 45360).
  - For a comprehensive listing of known issues for this core, please see the IP Release Notes Guide (XTP025).
