Due to the growing prominence of electronic equipment in day-to-day lives, VLSI or Very Large Scale Integration designing has become extremely common in the field of electronics. The integrated chips used in televisions, mobile phones, computers, laptops, cars etc. are created with VLSI technology. Therefore, the demand for job-oriented VLSI courses has also increased.
Before campus placements or job interviews, you need to be aware of some VLSI interview question. Different types of VLSI interview questions for freshers and VLSI interview questions for experienced professionals are prepared by recruiters. It is, therefore, recommended to practice a few questions beforehand.
Let’s check out some tricky VLSI interview questions.
What is the process of logical gates being controlled by Boolean logic?
In digital electronics, logic gates are used to implement Boolean expressions
What are the differences between the TTL and CMOS chips?
TTL or Transistor-Transistor logic chips consume less power in comparison to CMOS or Complementary Metal-Oxide-Semiconductor chips. The density of logic gates in CMOS is higher than TTL.
What do you mean by a sequential circuit?
The sequential circuit has a series of inputs and outputs. It contains a combinational circuit and memory storage elements.
How is Verilog different from any other programming language?
Verilog is different from other programming languages in the following ways:
● It has the concept of simulation time
● It has several threads
● Network links and primitive gates make the basic circuit idea
Explain the concept of Verilog?
Verilog is a Hardware Description Language or HDL that describes electronic systems and circuits. In Verilog, the circuit components are created inside a Module and comprise structural as well as behavioral statements.
What do you mean by Depletion region?
If a positive voltage passes through the Gate, positive charges or free holes are repelled from the substrate region under the Gate. A carrier-depletion region is formed when these pores are driven down the substrate.
What do you understand by Slack?
The time delay difference between the actual and expected delay in a given path is known as slack. It can be positive as well as negative.
Mention the different types of skews that are used in VLSI?
Three types of skews – Local, Global and Useful skew- are primarily used in VLSI. The Local Skew defines the difference between the launching flip-flop and destination flip-flop. The Global Skew, on the other hand, illustrates the difference between the earliest component reaching the flip flow and the latest component that arrives at the flip flow. In this case, the clock domain remains the same and delays are not computed. The delay in capturing flip flop paths is defined by the Useful Skew. It helps to create a specific environment for capturing the time path.
What makes the courses at Maven Silicon the best in the VLSI Industry?
Maven Silicon delivers some of the most efficient courses for VLSI training. The online courses are specifically designed to suit the requirements of different types of students. They offer full-time as well as blended VLSI courses, part-time courses, internship programs and corporate training. It makes the candidates industry-ready and completely equipped to prosper in a competitive environment.
