ID:274025 Net "<name>" contains multiple sources with at least one top-level pin but no destination port

CAUSE: The top-level input pin is joined with only output ports of EDIF cell instance(s) in the net. The net does not have a destination port.

ACTION: Specify a destination port for the pin in the source design file. In general, it is better to correct only the source design file rather than the EDIF Input File. If you prefer to edit the EDIF Input File, make sure that the file conforms to the format for EDIF version 2 0 0. If necessary, consult your EDIF manual.
