Environment

  • Arria® V GT FPGA
  • Arria® V GX FPGA
  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    No, Arria® V GX devices do not support transceiver PMA Direct mode.

     

    You may see the following error if you try and compile a Native PHY in PMA Direct mode on Arria V GX devices.

     

    Error: Channel PLL Parameter 'output_clock_frequency' is set to an illegal value of 'x MHz' and PMA Direct parameter is set to 'true'. If PMA Direct is false, the value is illegal for protocol mode: '' with a device speed grade of '6_Hx', PMA WIDTH of '' and byte deserializer mode : '' and latency '' on atom
