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.
