    From 11:50 to 12:10 what u said in the video is a bit contradictory I feel...Jitter doesn't affect HOLD because it affects both the launch clock and capture clock in the same way at the same edge...so it nullifies...whereas skew affects HOLD...because at the same edge capture clock might come before or after so it affects. So jitter doesn't affect Hold I guess...it is Skew that affects HOLD. Please tell me if I am wrong somewhere.

    Clock Jitter does not affect the hold time. Please correct the video otherwise it affects a lots of viewer's fundamental. Reference: Book: Static Timing Analysis for Nanometer design: a practical Approach by Rakesh Chadha and J Bhaskar, Springer Publication , Page No-31

    Clock Skew also affect the Hold time violation am i right?

    The T_hold value should be of the capture FF rather than the Launch FF right? You told T_hold of launch FF

    If there is a negative skew capture edge will come early, wouldnt it cause hold violation?

      @@VLSIAcademyhub Thanks for the response...my apologies, I mistakenly put wrong question. Wanted to check that finally skew will affect both setup and hold violations, but it doesnt come in equation of hold in above video.

    Sir can we consider clock uncertainty for hold time analysis
    Since clock uncertainty is combo of clock skew and jitter.
    Then what will be the total T required for hold time by considering uncertainty.
    Plz ans me

      Yes clock uncertainty place a very important role in hold timing analysis

    Hello, Does jitter affect the hold check?
    I don't think so
