ID:20705 I/O buffer node "<name>" has port "<name>" connected, but does not use calibrated on-chip termination.

CAUSE: The specified I/O buffer node uses the specified on-chip termination (OCT) port, but does not correspond to a pin that uses the calibrated OCT. The term_in port on the I/O buffer can be connected only when the corresponding I/O uses calibrated on-chip parallel or series termination.

ACTION: Either disconnect the term_in port or add a termination setting to the corresponding I/O.
