Description
You may see this error in the Quartus® Prime Standard and Pro edition software when using the Altera® LVDS SERDES Receiver IP in Arria® 10 devices and if you have any de-serialized (parallel) receiver outputs from the IP that are not connected in your design.
Resolution
To work around this error, either regenerate the Altera LVDS SERDES Receiver IP so that these bits are not implemented, or connect them up in your design.
