Hi,

I am not clear whether you get this Error in rtl or after pin planner.

I would like to suggest you check the below details,

https://forums.intel.com/s/question/0D50P00003yyNpESAU/altinbufdiff-and-pin-planner

In pin planner, assign the pin only to the positive pin of a differential pair, (n) pin will get assigned automatically by tool.

Refer the 'Assigning Differential Pins 'from link below,
