ID:176061 I/O pin "<name>", driven by a transmitter at <number> Mbps, cannot be placed at slow-speed pin <name>. The maximum allowed data rate for slow-speed LVDS is <number> Mbps.

CAUSE: An LVDS input pin has been assigned to a slow-speed LVDS location, which cannot support the data rate required by the receiver. The rate would be within range for normal LVDS, but slow-speed LVDS pins have a lower maximum data rate.

ACTION: Modify design to reduce receiver data rate or try to assign the input to a normal LVDS pin.
