    Hello,

    From waht I read, I think Quartus does not have enough info to conclude anything.

    In the SDC file you might need to update/correct your clock timing constraints.

    Best Regards,

    Thanks for your reply.

    And can you tell me how can I set timing constraints? Is it be set in the timequest in Quatrus timing analyzer?

    Thanks sincerely.
