ID:12214 Partition "<name>" requires synthesis because the project database does not contain a blackbox netlist for the empty partition

CAUSE: The Quartus Prime incremental compilation will synthesize the specified empty design partition because it could not locate a previously synthesized blackbox netlist for the partition in the project database. You may have deleted the database, or you may be compiling your design for the first time after setting the netlist type of this partition to Empty. The Quartus Prime generates the black box incremental results for an empty partition by removing all its internal logic except the pins and the logic needed for timing closure. These results are written out with map_bb synthesis extension. As a result, an empty partition will be resynthesized if it was previously synthesized with a non-empty netlist type.

ACTION: No action is required.
