Most Common Interview Questions: Type-3: Give Verilog/VHDL code ...

The prime intention of the interviewer in asking this question is to see the hands-on experience you have. If you have mentioned that you are familiar with Verilog/VHDL in your resume and attending an ASIC engineer post, then you can expect this question. This question usually comes after asking Type-1 and/or Type-2 questions (explained in previous posts). No interviewer starts with this type of question.

The common strategy followed is: initially you will be asked "Type-1: Design a ..." and then as an extension you will be asked to code it in Verilog or VHDL. Further, the interviewer may specifically ask you, to code for synthesis.

Tips
This question is asked to test your ability to code. Don't ever write a psuedo code or a code with syntax error(s).Prepare for this question by coding some basic programs like flip-flops, counters, small FSMs etc. Make sure that you touch most of the commonly used Verilog/VH…

Type-2: Tell us about a design/project you worked on

Most Common Interview Questions: Type-2: Tell us about a design/project you worked on

Prepare for answering this question in any interview you attend, its kind of inevitable. Usually our resumes will be flooded with some projects. So an interviewer, instead of asking about one of those projects, he simply hits the ball into your court by asking this question. In general, interviewers ask to talk about your best work, it could be a design you made out of your interest or a project or part of a coursework. Irrespective of whether interviewer uses the word best its implied that you are going to talk about your best work! Now the ball is in your court you have to give a smart reply using your skills.

How to answer this question?

Remember that the time you have to answer this is limited. So instead of explaining every aspect of your design in detail, give glimpses of your design. Start taking about the best or challenging part of your design. This is best way of extracting some questions fro…

Most Common Interview Questions: Type-1: Design a ...

This is the most common question one will face in his/her interview, probably the first question which starts testing your knowledge. (I mean this comes after introduction and "Tell us about yourself"). This is a lethal weapon used by the interviewer to test one's abilities: both weak and strong points. The concepts required for solving the problem are generally related to the type of job you are being tested for.

The most popular strategy used by the interview in this question is gradual increase in the complexity of the question. It goes like this ... Interviewer states the specifications of the design. You can present as simple/straight forward/redundant answer as possible. The next question could be redesign using only NOR gates or NAND gates. Followed by "what are minimum number of NAND gates required for this particular design" and it goes on.

Sometimes it starts with designing a small block. Then you wil…
