Error(21961): Input port OE of a "LVDS" I/O output buffer "" is not supported. - Error(21961): Input port OE of a "LVDS" I/O output buffer "" is not supported. Description In the Intel® Quartus® Prime Pro Edition Software version 21.1 and later, you might see this this error when you have an LVDS output with an output enable. In earlier version of the Intel® Quartus® Prime Pro Edition Software, this error did not occur but the output enable was not implemented correctly. An LVDS output with an output enable is not supported in hardware for Intel® Stratix® 10 devices or for Intel Agilex® devices. Resolution To avoid this error, do not include an LVDS output with an output enable in your design.
