Timing issue with arria 10

i’m trying to run the a10_soc_devkit_sgmii project (https://rocketboards.org/foswiki/Documentation/GSRD181ReleaseNotes#Release_Contents) with some modifications.
I’m running into some timing issues illustrated bellow.

what may be the issue?


Hello @gid,
try to look for answer at https://forums.intel.com/ rather than at Rocketboards.org. This forum is focused on software only.
But I think that slack as big as a period could be caused with inpropper Timing constrains (i.e. inpropper content of Yours SDC files).
Best wishes,
Yours Jan Konečný.
