GTX - TXPHINITDONE does not go High during simulation in ISIM


During phase alignment of master/slave GTX, the TXPHINITDONE of slave GTX does not go High.


This problem only happens when the RX side of the transceiver is not used. This is a known issue in ISIM and CR#735397 has been filed.

You can use one of the following as a work-around:

  • Use ModelSim for simulation.
  • Instead of ISE design tools, use the Vivado tool.
  • Include dummy RX channels in the design by unchecking "RX OFF" on page 2 of 7 series transceiver wizard as shown below:
