can LEC provide cdc check?

zhiweiwu0318

Who can kindly tell me which rule is cdc(cross domain check) in LEC? i can't find any clue in the document.

by the way, i used IFV for cdc, but it can't provide all un-synchronizer singals, oops!

    hi,
    thank you very much. i used normal mode not verify mode in Conformal previously, so i couldn't find cdc check. now it's ok, but i still had some problem about cdc check in LEC.
    1. I always got wrong result from LEC, do i need to define clock before check, or tool can automatically extract clock for me?
    2. I am still confused about synchronization rules. Where can i get more infomation about these rules besides Verify_Ref.pdf and Verify_User.pdf?
    thank you very much!
