POCV | Parametric On-Chip Variation | Static Timing Analysis | VLSI

This video covers the basics of POCV and how delay calculations are performed with POCV modelling in Static Timing Analysis in lower technology nodes.
Following topics are explained:
-Introduction to POCV
-What is POCV
-Normal distribution curve & Standard deviation
-POCV Data types & Analysis
-Delay calculation using POCV
-POCV calculations using an example timing report
-AOCV derates in POCV
-AOCV/POCV Comparison

This is a wonderful video, thanks a lot for your effort!!

[@p_phanindra3465]

Thanks mahendra for making pocv things clear... Kudos to u..

[@mmkr]

No problem. Thanks for watching.

[@praneethbogavilli5199]

Good information .Plz do as many videos as possible.

[@mmkr]

Glad to hear that. I’ll try my best 😊

[@nishadpadariya5341]

Thanks a lot for such informative video

[@mmkr]

You’re welcome.

[@kodidalamaheshbabu9242]

Thanks lot sir !! very helpful !!

[@mmkr]

Glad to hear that. Thanks for your feedback.

[@koteswararao.k2694]

Very Good Information

[@mmkr]

Thank you. Glad to hear that.

[@pavannaidu6021]

in timing report what is meant by statistical adjustment value? In place stage the value is zero and in CTS the value is added , can u please explain in brief

[@radhaa6564]

What is nominal delay?

[@kirtirajput531]

hey can u please explain what is exactly nominal delay?

[@ghanshu369]

Amazing video , thank you so much. Please advise , what would be meaning of cell check variation in yor presentation ?

[@mdhanunjayrao5667]

Nice information

[@mmkr]

Thank you

[@nareshtellakula3131]

Very informative,please make videos on annotation fixes

[@mmkr]

Thank you. I’ll think about that later.

[@user-kv3qq7gc1s]

What is statistical adjustment in 3 sigma timing reports can you please explain?

[@MrSatyanshuu]

What is the purpose of Corner? btw thanks for details :)

[@manju2323]

Is socv different from pocv analysis?

[@dhirajthalladi4934]

Hi sir, Great video can you please explain what is systematic variation and what does the distance in table Indicate I mean distance between what?

[@mmkr]

Thank you. Systematic variation is deterministic in nature and is proportional to the cell location of the path being analyzed. Examples of systematic variations are variations in gate length/width and interconnection width.These variations basically relate to proximity effects, density effects and the relative distance of devices. The cell path distance is determined by computing the diagonal of a cell bounding box which encompasses all of the cells in the path. Note, path distance is calculated separately for cells and nets, because a timing analysis tool assumes the locations of the nets in a path do not affect the systematic variation of the cells in the path.

@@mmkr Thank you sir

[@mmkr]

You’re welcome

[@vikineo]

can we add chapters with timestamp? easier to navigate the video that way.

[@mmkr]

Thanks for your suggestion, I’ll try to do it later.

[@radhaa6564]

Can you explain CRPR concept

[@AJAYKUMAR-ve2kk]

Hi Sir, i have one doubt, can you explain how AOCV derates impacts on Half-cycle paths & CRPR?

[@atuntripathy]

aocv has no impact of clock edge
