If you can spare half an hour, then we guarantee job search success with VLSI interview questions Do you want to secure at least 3 to 4 job offers by succeeding at all the phone and on-site Job interviews for this position?
Or you simply want most frequently asked VLSI interview questions with answers and digital design interview questions with answers? If so.. Did you know that people who made targeted question answer preparation for job interview are 4 times more likely to get job offer than those who dont?
Did you also know that there is a set of questions that is likely to be repeatedly asked by interviewers across the industry, no matter who you talk with in the field of digital VLSI design? How valuable would be to get hold of that set of questions? Do not worry, youve come to the right place for getting that set of questions and more importantly their answers.
You see, you already have a upper hand in your job search, as you have been doing research about interviews and about what kind of questions are asked in interviews. Let me tell you a bit about myself. I was not so lucky my friend. When I started doing interviews, I met with lots of rejections. I was not feeling much confident during interviews and I was getting cornered by some of the questions that were asked to me.
I kept getting turned down. I was utterly disappointed. I was extremely frustrated with my old job. I was tired of hostile work environment.
I was overworked and underpaid. It was extremely stressful. I was feeling like I was stuck and rotting at old job. This is when a new job had to be found, there was no choice. But early interview setbacks were disappointing. I started thinking more and more as to why I was failing? What was wrong with me? The failure was very much unlike me.
I was always a top brass performer at my previous job and I did extremely well at school. I started thinking back as to what was going on. Imagine what difference it makes when youre faced with something you already know and have practiced!! I started doing research, first I collected all the questions that were asked to me, then I scoured the libraries and books and found all important common VLSI interview questions, digital design interview questions, verilog interview questions, static timing analysis interview questions, logic design interview questions, ASIC interview questions, fpga interview questions and I got answers to all those questions.
Later I asked all my friends and all my colleagues who were working in the VLSI design field doing ASIC design, static timing analysis, CMOS circuit design and who themselves were interviewers, for frequently asked questions and found out definitive answers to all those questions. Thats how I came up with the set of questions and answers that youll find here.
By then I had already secured exactly the type of job I was looking for. I gave this set of questions to my friends who were searching for job, and all of them found it extremely useful. They recommended me that I make this available to general public, thats when I decided to make it available here. And now you can get full access to the same set of questions with answers. But what about the questions that are available on the Internet for free?
Why should I pay for it? Well my friend, would you leave something as important as a job interview to the chance?
In such a bad economy? I agree, its possible to find some good information for free on Internet. But most of the information on Internet is scattered, unorganized, outdated and not structured to be of value to someone like you.
At times it could be outright wrong!! Youve to make sure you get your information from a trusted, proven and very serious resource. I believe so strongly in this set of question-answers, I provide complete unconditional guarantee. You get very carefully chosen 95 of the most important, most likely to be asked questions with illustrated answered, when it comes to interviewing in the field of digital ASIC design, static timing analysis and CMOS circuit design.
Knowing answers to these questions will ensure that you get the job offer from your next interview. You see, it is very important to have enough confidence in yourself while interviewing. By far confidence matters equally if not more than to the knowledge you posses. If you can confidently present yourself in the interview, youll very much impress your interviewer. So the question is how do you get that confidence? Imagine if youve done proper preparation and if youve gone through those tricky questions and know answers to them!!
Youll carry much more confidence with you that will immensely boost your chances of success at your interview. How many times do we overlook the basics!! Especially if you have been working long enough at one place. These carefully selected questions brushes up on your basics knowledge about digital VLSI design. Youll have your basics covered by the interview time with VLSI interview question.
Not only you get answers to important questions, but the document also explain how to go about tackling some of the trickiest questions. Youll get to practice on important questions which in turn will flex your mental muscle and prepare you for the grueling of the interviews.
What is the difference between inertial and transport delays in Verilog? What is ITD, inverted temperature dependence? What does the setup time of a flip-flop depend upon? Come up with logic that counts number of 1s in a 7 bit wide vector. You can only use combinational logic. How does a substrate bias on a MOS transistor affect Vt? Divide a clock by 3. You have an input vector where on subsequent clock cycles you get a1,a2,a3,a4 values.
Youre given a black box which adds two input vectors and generates one output. Assume black box output latency input to output delay is two clock cycle. Design this circuit. If youre not satisfied with this product, any time..
Ill not ask you to destroy it, Ill not ask to return it back. I trust you and I believe in my product so much that I stand behind it with such a solid money back guarantee. I finally found answers to the questions that you find everywhere on all other sites. I recommend this if youre looking for questions with answers and not just the questions.
Robert T. Lee San Jose, CA. I was initially skeptical, but I was pleasantly surprised when I was asked the same questions from this set, in my next interview. This set is a must read! Phil Nguyen Austin, TX. Youll not only get answers, but youll learn methods as to how you should approach tackling tricky questions.
Its a condensed revision that we all want to do. Srinivas Ramasundar Bangalore, India Do not wait!! Youve posted your resume and have applied for positions, you might get your next phone screen request sooner than you realize, dont get caught unprepared.

Go through any VLSI book from beginning to the end 2. If possible solve all the problems at the end of the chapter 3. Most basic question is draw digital gates using transistors, difference between bipolar and cmos , analog and digital why cmos 4. Go through the details on your project 5. Refresh your circuit theory, basic LCR circuit , transfer function Why must transistors be provided with bulk connections? What voltage levels are connected to a p-type substrate and an n-type well through these connections, and why?
To make the parasitic diodes reverse biased. What is their major purpose? How are design rules created? Such diagrams are especially useful in complex processses, such as DRAM processes.
Are you familiar with the term MESI? Are you familiar with the term snooping? Describe a finite state machine that will detect three consecutive coin tosses of one coin that results in heads.
In what cases do you need to double clock a signal before presenting it to a synchronous state machine? You have a driver that drives a long signalconnects to an input device.
At the input device there is either overshoot, undershoot or signal threshold violations, what can be done to correct this problem? For a single computer processor computer system, what is the purpose of a processor cache and describe its operation? Explain the operation considering a two processor computer system with a cache for each processor.
