VLSI Interview Questions, Answers for Freshers and Experienced asked in various Company Job Interviews

VLSI Interview Questions with Answers

As I mentioned earlier + Find out from your company research and from the job description what strengths the company puts a lot of stock into. This means the statements within the begin…end block are executed in the order they appear within the block. This clock helps in maintaining the flow and synchronizing various devices that are used. The resulting fault detection rate may be statistically inferred from the number of faults that are detected in the fault set and the size of the set. This helps in recovering the metastable state event. You must display a competency for understanding the difference between internal and external customers. Ans: A sequential circuit is a circuit which is created by logic gates such that the required logic at the output depends not only on the current input logic conditions, but also on the sequences past inputs and outputs.

How the width of metal and number of straps calculated for power and ground? It consists of electrons as their carriers and migration happens between the n-type source and drain. Ans: The steps that are involved in which the design constraint occurs are: 1. For a single computer processor computer system, what is the purpose of a processor cache and describe its operation? The gates are connected using the power or ground then it can be turned off and on due to the power bounce from the ground. Ans: The optimization technique that is used makes it difficult for the chain ordering system to route due to the congestion caused by the placement of the cells. It will determine whether the fault coverage exceeds a desired level. Chain reordering allows the cell to be come in the ordered format while using the different clock domains. Each node or line to be faulted is set to 0 and then 1 and the test vector set is applied.

This type of random glitches are more likely to happen if reset is generated by some internal conditions, which most of the time means reset travels through some combinational logic before it finally gets distributed throughout the system. If every employee employer hire is willing to engage in conflict resolution, more new ideas and better approaches to solving problems will take place in your organization. The answer is a resistor. . This effect, which is caused by applying some voltage to body is known as body effect.

This reduces the metastability by removing the delay that is caused by the data element that are coming and taking time to get removed from the surface of metal. It is a type of rectifier that is controlled by a logical gate signal. Because I was the one to take the lead the discussion and had a plan in mind, I gained the buy in of the other members quickly. A16: Higher the number of stacks, slower the gate will be. So input are restricted to four.

The employees who can rise to a challenge and think of innovative ways to solve a problem are the ones who go on to achieve great things both for themselves and the business. To avoid this, every rows are flipped so that Vdd of two rows can be joined together and Vss of two rows can be connected together. N-mos device has inherent resistance and we can achieve the desired resistance by modulating the width of n-mos transistor. Behavioral model of comparator represented like: What is the function of chain reordering? Ans: To make a comparator there is a requirement to use multiplexer that is having one input and many outputs. You may be asked something like the below in order to test if you are a strong team player: Question: Give an example of team leading in past employment Answer: You should summarise the task and nature of the group but focus primarily upon your role as team leader. Generally, these questions require interviewees to describe a problem or situation, the actions they took to handle the problem, and the results of the situation. Can you think of a cell phone which has to be charged for every call.

Interviewers always ask if you have any questions, and no matter what, you should have one or two ready. What parameters or aspects differentiate Chip Design and Block level design? A ring counter is a type of counter composed of a circular shift register. It is a type of rectifier that is controlled by a logical gate signal. It is used to reduce the time delay caused by random generation of the element and the placement of it. Dynamic gate has two operating phases based on the clock phases.

VLSI Interview Questions with Answers

This also uses the unipolar transistors to differentiate themselves with the single-carrier type operation transistors that consists of the bipolar junction transistor. It is a type of rectifier that is controlled by a logical gate signal. High input impedance low drive current. Differentiate between chip level design and block level design? What are the different classification of the timing control? This provide a way to setup the state through which it can be known that the violations that are occuring in the system and a proper design can be provided by the use of several other functions. But in such a case, the combinational logic gate count grows, so the overall gate count savings may not be that significant…. Synchronous reset flops are smaller as reset is just and-ed outside the flop with data, but you need that extra and gate per flop to accommodate reset. Ans: With the keyword defparam, parameter values can be configured in any module instance in the design.

If a tree falls in the forest and no one is there to hear it, did it make a sound? This is the pre-charge state of dynamic gate. Customer focus interview question: Your ability to understand and believe in the importance of customer focus will be tested here. There are a few position in the custom design, circuit design, memory design and analog or mixed signal design. For sake of comprehending this issue, we will go through an overly simplified delay model. For gates it is the time it takes for a event at the gate input to affect the gate output.

This reduces the metastability by removing the delay that is caused by the data element that are coming and taking time to get removed from the surface of metal. Designs are increasingly being clock gated to save power. Start the process while at the interview, thanking each person who interviewed you before you leave. When a level changes the timing control also changes. Sometimes, interviewers deliberately keep you waiting to see how you respond.

Specify the case-settings to report the correct time that are matched with the specific paths. Q15: Explain What Is The Depletion Region? This is due to the fact that if a metal gets the etching then the other metal gets disconnected if the prevention measures are not taken. Logic density is less Channel less Gate Array: Only the top few mask layers are customized. What are the different classification of the timing control? Tips to answer this question: + Demonstrate when you answer the question your level of commitment to the position they are interviewing you for. This means they could be executed in any order and the order could be change from time to time. Max delay is used for launch path and Min delay for capture path b. Then, follow up with an example of how you've demonstrated these traits in a professional setting Tips to answer this question: + Grab hold of the opportunity this question gives you.
