ID:169313 <name> logic option assignment cannot have I/O pin <name> as a source node because the pin has I/O standard <name>

CAUSE: You assigned the LVDS Direct Loopback option from the specified source node to some destination node. The source node must use true differential input buffer, but the specified I/O standard does not use true differential input buffer.

ACTION: Choose a different I/O standard for the pin, or remove the LVDS Direct Loopback assignment to the pin.
