Error (11176): Alt_sld_fab.alt_sld_fab.stfabric.demux: "Number of Output Ports" (numOutputInterfaces) <Number of Channels> is out of range: 1-16

Environment

  • Intel® Arria® 10 GT FPGA
  • Intel® Arria® 10 GX FPGA
  • Intel® Arria® 10 SX SoC FPGA
  • Intel® Cyclone® 10 GX FPGA
  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You may see the above error in Quartus® Prime software version 15.0 when implementing a transceiver design that contains greater than 16 channels and has a separate ADME (Altera Debug Master Endpoint) interface per channel in Arria® 10 and Cyclone® 10 devices.

    Resolution

    To work around this problem, you can change the constant in the following file

    *quartus/libraries/megafunctions/altera_debug_master_endpoint.vhd


    –from :constant NUM_CLOCKS  : natural := 0;

    –to : constant NUM_CLOCKS   : natural := 1;

    This problem will be fixed in the future version of the Quartus Prime software.
