Internal Error: Sub-system: EMIF, File: /quartus/periph/emif/emif_gen6_netlist_modifier.cpp, Line: 1213

Environment

  • Intel® Quartus® Prime Pro Edition
  • External Memory Interfaces Intel® Arria® 10 FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    When there are multiple external memory interfaces placed in the same I/O column and the Arria® 10 EMIF IP Diagnostics tab Calibration Debug Options parameters are not configured correctly, an Intel® Quartus® Prime software internal error message of this type may occur:

    Internal Error: Sub-system: EMIF, File: /quartus/periph/emif/emif_gen6_netlist_modifier.cpp, Line: 1213
    Expected only one, but found 4 atoms with SOFT_NIOS_ADDR port connected!

    Resolution

    Configure the Diagnostics tab Calibration Debug Options for the EMIF Debug toolkit, daisy chaining, and Interface ID parameters correctly for each interface.
    Refer to the Intel® Arria® 10 Debugging Multiple EMIFs wiki page for details which shows an example project containing 3 interfaces with daisy-chained EMIF Toolkit connections.

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