Why does the F-tile PMA/FEC Direct PHY Intel® FPGA IP design example fail at logic generation for Intel® Agilex™ devices??


  • Intel® Quartus® Prime Pro Edition

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.1, the F-Tile PMA/FEC Intel® FPGA IP for Intel® Agilex™ devices will fail during the compilation process when you enable double width with PMA width 16. The following error messages will appear during the Logic Generation stage:

    • Error(21843): Conflict 0

    This problem occurs because the F-Tile PMA/FEC Intel® FPGA IP does not support PMA width = 16 when in double-width mode.


    To work around this problem, do not generate the F-Tile PMA/FEC Intel® FPGA IP with PMA width = 16 when in double-width mode.

    For more information on supported configurations, refer to the F-tile Architecture and PMA and FEC Direct PHY IP User Guide.


    This problem is scheduled to be fixed in a future version of the Intel® Quartus® Prime Pro Edition Software.
