RC circuits and Op-Amp questions are important. The interview process started in the early morning in their company building. We were around 12 students from the same college. The HR alone met us. The cadence HR took two rounds of written tests Digital and Analog. The digital written test round was a bit easy. Verilog and basic digital circuit design based on problem statement questions were there. And the analog written test was tough, so many in-depth questions were there. Knowledge network theory and series RLC circuits were a must need. The shortlisted students for both sections separately. Few aspirants were selected for both analog and digital profiles. Then they conducted
FSM-Finite State Machine-Questions-Answers | DIGIQ Digital Interview by VLSI Universe - April 30, 2020July 21, 20210 The Sequential FSM Finite State Machine DIGIQ based questions are very important for any digital interview. Sharing a few of the FSM questions with answers. The question sequence or pattern detector will be a fixed question in many written tests such as NVIDIA, Western Digital, Analog Devices, etc. FSM Finite State Machine Questions and Answers 1. Design a finite state machine FSM for a serial two's complement block and also draw the logic diagram associated with it by using D-flipflop. Answer: The main logic behind this is, start from the least significant bit and retain the bits until and first 1-bit has occurred. Once a 1-bit is found, start complementing the bits if 1 makes it 0 and if 0 make it 1. Note

Top 10 interview puzzles with answers Interview Questions by VLSI Universe - April 24, 2020July 21, 20210 These are the most asked interview puzzles with answers or solutions of 2020. Collected from logically, analytics and geeks for geeks. 1. Using two wires measure 45minutes of time Puzzle question: If a wire takes one hour to burn completely, and the condition is the wire will burn non uniformly. (For example first half of wire may burn in 10min and second half may burn in 50min). Then how will you measure the 45 minutes using the given wires? Puzzle solution: Here the idea is to take a wire and burn from both the ends, which will get burn in half of the time that is in 30 minutes. To get the answer to the asked question first take the wire 1 and burn from both
STA-Static Timing Analysis-Setup and Hold 2021 STA by VLSI Universe - April 24, 2020July 21, 20210 The timing performance of the VLSI or ASICs is checked by either STA Static Timing Analysis or DTA Dynamin Timing Analysis. STA is a technique or method of breaking the circuit into different paths and computing their delay and based on the delayed outcome it validates and verifies the design. let us look into the same. Also read which were asked in VLSI interviews STA Solved Problems Introduction The main headache of any digital or VLSI design engineer is the timing while designing a CMOS semiconductor chip. How to model it and how to verify the timing. The design team may take a huge amount of time may be spending some months in modifying and making trials to achieve or to meet the required
Crosstalk and Crosstalk delay effects CMOS by VLSI Universe - April 23, 2020July 21, 20210 In the SI of Physical design, the design will be verified for crosstalk, crosstalk noise, and delays. In the situation when one of the wire switches, the wire will tend to change or affect its neighbor through capacitive coupling. This effect is called Crosstalk. The digital design functionality and its effective performance can be limited by noise. This noise occurs mainly due to the crosstalk with other signals. And it also may occur due to noise on primary inputs or the power supply Vdd. Crosstalk delay effects In the situation when the wire and its neighbor wire are switching simultaneously, the direction in which both are switching will affect the amount of capacitance that must be delivered to the destination and also the
Transistor sizing W/L | CMOS | VLSI CMOS by VLSI Universe - April 23, 2020July 21, 20210 The sizing of the transistor can be done using RC delay approximation. The RC Delay Model helps in delay estimation CMOS circuit. The RC delay model treats the non-linear transistor current-voltage I-V and capacitor voltage C-V characteristics with their equivalent resistance and capacitance model. This RC delay model approximates a transistor as a switch with a series of resistance or effective resistance R (Which is the ratio of the average value of Vds to Ids). The size of a unit transistor is approximated as 4/2 lambda. The RC circuit equivalent models for the PMOS and NMOS transistors are shown below. Here the k width of both PMOS and NMOS transistors is contacted to Source S and drain D. Since the holes in
FIFO Depth Calculation VLSI Digital Interview by VLSI Universe - April 23, 2020July 21, 20210 The FIFO depth calculation made easy(use synchronizers) is the most asked question in the interviews and a very important topic any VLSI or Electronics engineer must know. When we want to establish a connection between two different asynchronous clock blocks a common option is to use synchronizers. Here the term asynchronous clock domain refers to the blocks of circuits which do not share a common single clock. Let us understand how the connection can be established between them.
