I am terribly sorry this is completely out of my capability. I really dont know how to do it. Why I raised this patch is b.c. The diff does show a very distinct difference on Altera trunk and mainstream. And I did try what you had proposed (delay) and zero different b.c. that calibration is under a long test somehow. I even tried adding a redo counter. And also had tried to check what was done before and after the calibration and no major diff was found. So to simply generalize the issue I patched this patch. If you had a clue that is not the case then I am 100% wrong not to be shamed. I did not undergo code investigation first, I did it by reverse behavioral observation. Bests, Brian
