ID:274021 Net "<name>" connects a bidirectional port "<name>" to an input or output pin

CAUSE: In an EDIF Input File (.edf), the specified net connects the specified bidirectional port to an input or output pin, but the port must connect only to a bidirectional pin.

ACTION: Connect the bidirectional port to a bidirectional 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.
