### VLSI Basic

Here we are targeting the different basics of VLSI from very starting point (Digital Back ground) till understand the meaning of "What is VLSI".
I have divided the all the post in different chapters and then subsections (As per the below index).

If you think, I have missed any topic, please let me know. I will try to cover that in this section (if possible) else I will let you know by when and where It will be included.

Note: Below Index can be changed because of more detailed sections or New topics but broadly following topics will be covered.

Chapter 1 : Digital Background
Chapter 2 : Semiconductor Background
Chapter 3: CMOS Processing
Chapter 4: CMOS Basics
• MOS design (type of MOS/PMOS/NMOS/CMOS)
• CMOS Gates
• CMOS basic working principle
Chapter 5: CMOS Layout Design
Chapter 6 : MOS Modeling:
• Differennt Prperties
• SPICE models
• Simulation with MicroWind

Chapter 7: Few VLSI terminology
• Symol, Schematic, CELL, LIBRARY
• Timing , Power, Area,
• Driving Strength, Slew, Transition Time, Propagation Delay,
• Nets, PINS, Clock Circuit, DATA paths
• Clock paths, Layout , Standard Cells
• Library Cell Design

Chapter 8: VHDL-Verilog Basics
Other:
1) Twin-tub (Twin -Well) CMOS Process
2) Silicon On Insulator (SOI) CMOS Process

1. first, u are doing awesome work....and it will help lots of people thinking to make carrier in vlsi including me....

sir, other topics are not visible....and please add as much as examples on different complex circuits using mux and decoders...

2. Hi Mayur,

I am updating other topics .. one-by-one.. It will take some time to update on the site. I will try to include examples or references as much as possible - so that every one can clarify their concepts.

1. sir, can u plz help me to find more information on sequential circuits and basic flip flop

2. Sure, I will try my best to do it asap

3. Dear Administrator now,i think its time to update your blog,at-least complete those remaining topics as it have been a year now. Chapter-1,2&4 are the basic ones.Please at least fill them with your great work. Again your work is extremely good,that's why people wants you to,..pls pls pls..

3. If you want a help. I can help you updating other topics and you can edit it if you want, that will help you save time. Email me at hainam311@gmail.com.

4. if you want a volunteer. Email me at hainam311@gmail.com

5. Eagerly waiting to enhance my knowledge in remaing topics.... Hope the unseen topics will b updated soon........

1. Hi Palas,

I am working over that.. Soon I will update few more.

2. ok. Thanks a lot.

6. thank you so much sir for giving such a wndrful explanation about basics..........but as all are said i am exiting to learn remaining topics.plz update as early as possible..thnka in advance........

7. sir I really thank you from d bottom of my heart...I m pursuing mtech in vlsi and I really needed these topics...u dnt knw hw much I was in need of them...thank you very much sir

8. sir I need mos device and spice models...can u please update them soon

1. Hi,

MOS device is in process and it will be uploaded sometime in this week.

Spice models - can take some time - but I will see if I can prepare on the priority basis.

2. sir I request u to upload them as soon as possible coz I really need it...thank you sir

3. I am in the process.. Few I have uploaded and few are in line. Please check the "latest" section.

9. Dear Administrator now,i think its time to update your blog, at-least complete those remaining topics s it have been a year now.Chapter-1,2&4 are the basic ones.Please at least fill them with your great work.Again your work is extremely good that's why people wants you to,..pls pls pls..

1. Thanks for Showing interest. I become busy in the other topics. Topics on CMOS are almost ready. I will update soon.

10. I am in 6 sem n now I am going to study about vlsi it helped me to know the basic thnks. ..I want to become a vlsi engineer can u guid me

1. Drop me a mail and I will try to help you or guide you.

11. Hi Sir,
I am planning to move into physical design can you please provide the topics I need to be covered and tools that can be helpful.

12. Thanks a lot for all this great work! It is VERY helpful! Thanks for taking out your time to help so many people!!!!
Could you please upload the remaining sections for digital background and the CMOS working as soon as you get some time?

13. can you send me material regarding to chapter 6 & 7? at hm1622@gmail.com

14. Hai sir,
i am planning to move vlsi layout . Can u please forward me the material and contents to my mail id: mopidevisravani.475@gmail.com and tell me the top related sites to improve my knowledge

15. What is resource sharing? Please illustrate this example using a piece of Verilog and draw a picture of the hardware produced in 2 cases (with and without resource sharing)

16. why are higher metal layers used for power and ground rails???

1. There are lot of reasons but for you ...
1) these are very close to outside Power Pins.
2) Metal Width and Thickness are large - So less resistive in nature. So less Voltage Drop , if we will use these For Power and Ground.

17. Hey, Can you mention me which book to refer for VLSI basics ( MOS transistor theory ) ? As I see many books in the market but confused to select one.

18. plz do fast sir we need more interview questions and answers

19. Hello sir, if possible can you please update chapter 7 ( VLSI terminology topics as you mentioned in this blog).

20. some of the topics are not visible... 1.6b,1.7,chapters-2,4,6,7,8

22. Sir i want to be the verification and design engineer in vlsi field
plzz enlighten me with the topic and material the i should read for it.

23. Well explained about basics of VLSI. Before I have studied VLSI but some of the topics was not clear to me. After reading your post it was all explained.
Thanks a lot sir.

24. sir,
What is the meaning of 16 in 16 ffc technology? Is the following explanation correct?

In advanced CMOS technologies, e.g. 32nm, 28 nm, these numbers usually refer to 1/2 the contacted pitch of the DRAM ,(as they are the most compact circuit which can be fabricated out) which is also 1/2 the pitch of the first level of metalization (the closest to the silicon substrate). It is close to the printed gate length of transistors, but not identical(due to overlapping of gate with source and drain region, which further leads to parasitic overlap capacitance).

25. Hi sir,
Ur doing a great work please give information regarding missing topics and help the students and professionals

26. Dear Sir, in your book, please include a topic on the following: difference between latch and flip-flop, and metastability of flip-flops.

27. I cant open 1.7 the link is nit available

28. very nice explanation...plz help us by posting all missing topics..plz...

29. Sir .. your explanation was very good... Add missing topics also... Eagerly waiting for
