LVDS Differential IO pin Mapping error

If you really want the signal names ADC_p and ADC_n instead of the tool's auto generated (n) name use this process. It is a workaround I

use. It is a pain :-(

1) Change all I/O standards for p and n to 2.5V

2) Assign the single ended p and n on to the diff pin pair you want to use on the pin planner

3) Change them one by one to LVDS_3_R standard and change their diff pair partner

e.g. assign data_p[0] to Y6, assign data_n[0] to Y5.

Change data_p[0] to LVDS_3_R.

next change the complementary signal in the pin planner ‘Differential pair ‘ column from data_p[0](n) to data_n[0] and then press ‘enter’

it will ask you if you want to change data_n[0] to LVDS_3_R. Click yes

That’s one done, each one has to be done individually
