ID:169312 "<name> logic option assignment cannot have I/O pin <name> as a destination node because the pin has I/O standard <name>

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

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