Let's Program the Transistors
Sequential machines can be designed in two different ways: (i) Mealy Machine & (ii) Moore Machine Considering Mealy or Moore for the designing of sequential machine, it’s actually difficult to draw a hard line where one machine is always better than the other. Depending on the application requirement one may dominate the other. It is…

Design of sequential circuit can be composed of designing combinational circuit and state register. Sequential circuits are implemented in two different ways: We can represent a sequential machine as M = <I,O,S,f,g>; where I: Input setO: Output setS: State spacef: A function mapping IxS = Og: A function mapping IxS = S Let’s understand both…
Verilog language has the capability of designing a module in several coding styles. Depending on the needs of a design, internals of each module can be defined at four level of abstractions. Irrespective of the internal abstraction level, the module would behave exactly in the similar way to the external environment. Following are the four…
Aricent Technologies Technical Interviews Question Bank continued from Part 6 Q-31. What are the different flags supported by the 8086 microprocessor? A : The 8086 microprocessor has the following flags – carry flag, auxiliary carry flag, parity flag, zero flag, overflow flag, trace flag, interrupt flag, direction flag, and sign flag. Q-32. Which type of…

Aricent Technologies Technical Interviews Question Bank continued from Part 5 Q-26. What is the difference between microprocessor and microcontroller? A : Microprocessor is an integrated circuit that only has processor (i.e. CPU – Central Processing Unit) inside it and requires RAM, ROM, peripheral devices such as keyboard, seven-segments etc. to be externally interfaced to it….

Aricent Technologies Technical Interviews Question Bank continued from Part 4 Q-21. Give a brief description about circuit switching and packet switching. A : Circuit switching is a type of method for implementing a telecommunication network in which a dedicated path or physical connection is established before transmission of data. Dedicated connection allows full-duplex, fast, safe…

This post contains some very interesting interview questions asked by Synopsys the EDA giant in its interview. The questions are based on Verilog Synthesis and Simulation. Though I have included the answers; I would encourage the reader to experiment himself or herself and then discuss these in the forum. 1. How a latch gets inferred…

Aricent Technologies Technical Interviews Question Bank continued from Part 3 Q-16. What is half-duplex channel? Give a real-life application of it. A : Half-duplex channel is a medium of communication in which the sender and receiver are capable of transmitting or receiving but not both at the same time for example, a walkie-talkie. Q-17. What…

Aricent Technologies Technical Interviews Question Bank continued from Part 2 Q-11. What is TDMA and FDMA? Explain their difference. A : TDMA refers to Time Division Multiple Access which is a channel multiplexing technique where users are assigned different time slots such that eight simultaneous calls can be made using the entire bandwidth. FDMA stands…

Aricent Technologies Technical Interviews Question Bank continued from Part 1 Q-6. What are active and passive components? Give examples of both. A : Active components are components that produce energy (in the form of voltage or current) such as transistors, while passive components consume energy like resistor, capacitor etc. Q-7. Why is input resistance of…
