ID:287107 BIDIR pin "<name>" cannot be assigned more than one value. Created single value from multiple values, but single value cannot be used.

CAUSE: In a Text Design File (.tdf), you assigned multiple values to the specified BIDIR pin. Analysis & Synthesis performed a logical OR operation on the values to create a single value, but you cannot use the created value because you cannot use logic to drive a BIDIR pin.

ACTION: Assign the multiple values to the input of a TRI buffer, and drive the BIDIR pin with the TRI buffer.
