Error (169033): I/O pin with Termination logic option setting OCT 100 Ohms cannot be placed inside I/O Bank because the I/O bank does not support the requested Termination setting

You will get this error if you are trying to assign a differential termination to a LVDS input that resides in a general purpose I/O bank (i.e. not a transceiver I/O bank) with the incorrect termination assignment.

The OCT termination assignments are for transceiver inputs only.

To assign a 100-Ohm differential termination to an LVDS input pin, in a general purpose I/O bank, make the following assignment :

set_instance_assignment -name INPUT_TERMINATION DIFFERENTIAL -to <pin_name>

Note that the I/O standard must be LVDS for this option to be supported.
