Description
When referencing the Intel® Cyclone® 10 LP Device Overview, note that the LVDS pair is only counted as a pair if there is a p and n of the pins.
If there is only p but no n, it is not considered an LVDS pair. Also, the DIFFCLK pins in the pinout are also considered a pair. Therefore, LVDS pairs are counted by the DIFFIO pairs and DIFFCLK pairs.
Resolution
This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software
