Internal Error: Sub-system: CDB_ATOM, File: /quartus/db/cdb_atom/cdb_atom_sys.cpp, Line: 2682


Due to a problem in the Intel® Quartus® Prime Pro Edition software version 17.1 Update 1 and earlier, you may see the following internal error during compilation of an Intel Stratix® 10 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.


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

This problem is scheduled to be resolved in a future release of the Intel Quartus Prime Pro Edition software.
