VLSI Interview Question: STA Solved 5 | Effect of #clock skew and jitter on setup time
Hi everyone, welcome back to another episode of "VLSI Interview Question: STA Solved"! Today, we're diving into an important topic: how clock skew and jitter affect setup time in ASIC design.
In the semiconductor industry, timing analysis is crucial at every step of designing chips. It helps us fix issues like setup violations right from the blueprint stage to the final physical design.
In this video, we'll cover:
What clock skew is and how it impacts timing.
How jitter (those tiny timing fluctuations) can mess with setup times.
Practical examples and simulations to show you how these things work in real circuits.
Whether you're a VLSI professional or a student eager to learn more about timing analysis, this video will give you practical insights that you can apply.

In the industry, timing analysis is performed at every level of the ASIC design flow, and various techniques are used to address timing violations at each stage. For example, changes can be made at the architecture level, RTL level, and physical design level. It is crucial to understand how these techniques are applied to fix setup violations in the design. #vlsijobs #vlsicareercraft #vlsitrain...

    Nice explanation. Just 1 point though.. Adding delay/buffer in data path increases setup timing So it is making it worse right? I mean now data needs to reach D pin much earlier right?

  • @SKRNSM-r7z
    @SKRNSM-r7z 3 หลายเดือนก่อน

    For FF1 to FF2 there are two inverters in clock path effectively if we don't consider the common inverter delay between FF1 and FF2. So, now two inverter delays are giving negative skew which is fine. But what about clock jitter madam, I'm confused like do we have to consider only -2*(jitter) always irrespective of the number of inverters in clock path? Tclk+tskew-2*(jitter) is what the original equation on right hand side for setup analysis. But will that -2*(jitter) term changes if there are multiple delays, let's say inverter and buffer is also there with each having same plus or minus 10% delay variation. Then will the equation holds same or it will change?

      Thanks for the question! The terms tj1 and tj2 in the generic equation which given in slide 2 refers to the amount of random deviation of each clock edge. Whenever the inverter delay is given skew and jitter depends on no. of inverters but when jitter is mentioned in the question then it would be -2*(jitter)

    Hii madam, Can you make video's on timing exceptions Multi cycle path, Half cycle path , False path and also videos on how to reduce congestion in different ways. If we get these videos by this Saturday then it will be very help for me, if not possible it's okay madam. Thank you for such wonderful content.
