Environment

  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 17.1 Update 1 and earlier, you might see the following internal error during compilation of an Intel® Stratix® 10  FPGA design containing DUPLICATE_ATOM assignments.

    Internal Error: Sub-system: CDB_ATOM, File: /quartus/db/cdb_atom/cdb_atom_sys.cpp, Line: 2682
    Fanout can only be added to atom in same netlist.


    The problem occurs when the "-from" node and "-to" node specified in the DUPLICATE_ATOM assignment are in two different design partitions.

    Resolution

    To work around this problem, ensure that "-from" node and "-to" nodes specified in a DUPLICATE_ATOM assignment are within the same design partition.
