    [DFT] Pre DFT and post DFT DRC difference

    Hello All,

    Can anyone please let me know what is the difference between pre DFT DRC and post DFT DRC? Why we have to do DRC checks at both pre and post stages?
    Which things are not done at Pre DFT, so those checks are done at post DFT?

    Thanks in advance.

    Thanks & Regards,

    Re: [DFT] Pre DFT and post DFT DRC difference

    THe main criteria is Fault Coverage with criteria for Detection and Isolation that will affect routing pre and post-DFT for sync timing and loop area.
    A best design is easily achieved with good test specs™
    A better question deserves a better answer. ™
    ... so include all your acceptance criteria ( values, % tolerance) and assumptions in your question or any design.
