Error (169175): Pin # with LVDS I/O standard needs a differential output?

Hi, I'm using a Terasic DE10-lite board with a 10M50DAF484C7G MAX 10. I'm trying to use some LVDS differential outputs but I get this error: Error (169175): Pin "GPIO" with LVDS I/O standar...

Hi,

From your error message, seem like you are assigning the LVDS I/O standard in both positive (p) and negative (n) pin.

As we understand LVDS is a differential signaling system, meaning that it transmits information as the difference between the voltages on a pair of wires.

You will only need to assign the LVDS I/O standard for positive (p) pin, Quartus software will auto generate the negative (n) pin which had inverted automatically to pair with the p pin.

Best Regards,
