  • VHDL is not supported for the Root Port configuration at the time of this release.
  • Core Interface Signal change.
    • CR 579319
    • The transaction interface has been updated to use m_axis_rx_tkeep and s_axis_tx_tkeep, instead of m_axis_rx_tstrb and s_axis_tx_tstrb.
  • TLP Drop issue resolved - 8-lane Gen2 configuration only.
    • CR 593825
    • Issue resolved where a TLP presented at the User Transmit interface was getting dropped by the AXI bridge. The TLP would get dropped when there was a concurrent transmission of an internally generated TLP.
  • 64-bit writes not accepted by PIO_64_RX_ENGINE.
    • CR 591524
    • Issue resolved where the PIO_64_RX_ENGINE VHDL testbench file did not correctly accept 64-bit writes.
  • XISE file updated to include the correct file set.
    • CR 585191
    • Issue resolved where the path of a file in the ".xise" file was incorrect causing the file to not get pulled in correctly.
  • GTX DFEDLYOVRD setting updated.
    • CR 594024
    • The DFEDLYOVRD setting in the GTX wrapper has been updated to be set to '0', per GTX User Guide recommendation.
  • Buffering Optimized for Bus Mastering applications with 512 byte MPS.
    • CR 591841
    • Issue resolved where the Example Design Simulation was not working when Buffering Optimized for Bus Mastering Applications option was selected, in conjunction with MPS setting of 512 bytes.
