Super ContributorHi,
inverted pins of differential pairs are assigned automatically by the fitter, you don't need to enter it in pin planner. Does the error also come up if you only assign p-pins?
New ContributorHi,
As you pointed, leaving the n-pins unassigned seem the fitter associate them automatically to their complementary ones.
However, we are allowed to direclty assingn the n-pins from lane 1 without any issue but not the ones belonging to lane 2 as the following image shows
We would like to know what is the reason why one lane allows direct assign and the other no. Both lanes belong to the same HSIO bank. In the case shown in the image, would all LVDS lanes work properly?
Thanks in advance
