  • Ans. 

    Setup time is the minimum time required for the input signal to be stable before the clock edge arrives.

    • Setup time is a critical parameter in timing analysis of sequential and combinational logic.

    • It affects the system by ensuring that the input signal is stable before the clock edge arrives, preventing errors in the output.

    • The minimum clock frequency can be calculated using the formula: Fmin = 1 / (Tcq + Tsu + Thold), ...

  • Q4. Due to some other type of fabrication, if clock frequency happened to be more than whatit is supposed to be(the one calculated above), how do you handle that situation?

Interview Preparation Tips

Round: Resume Shortlist
Experience: Shortlisted 8 students from resumes for interview.

Parameters for shortlisting (at each stage of process):Varied ResumeAny work done in FGPACG - I had CGPA of 8.66Internship - Was an Intern at QualcommProjects - Digital IC Design-used Standard Cell Design,Wireless-OFDMsynchronization and channel estimation,Automatic speech recognition)

Round: Technical Interview
Experience: Only 1 round of interview was taken.No HR round and only Technical Questions were asked.

Basics in our courses(state diagrams etc.) were tested.Concepts were explained and was asked questions. So, skill ofgrasping and applying were also testedSpeed didn’t matter. How aproblem was approached,thought were testedNo knowledge regarding minors/electives tested.

For Core:No courses/electives looked at(as nothing related to FPGA is taught)Nothing related to BTP/DDP
Tips: Good skills of maths might help.

In the interview, in 2nd question which was mentioned, whether repetition isallowed or not was asked by the candidate.This really mattered as that was theonly thing different he has done from the person who did an intern in FPGA andit might helped in getting selected finally :)

Skills: Grasping Power, Approaching a Problem, Thought Process, Math Skills, C++, C, Python, Matlab, Networks, Digital Signal Processing, Data Structures , Digital Systems, Algorithms

Swap two integer using pointers. 3.An algo for finding weight to weigh 1-40 kg using min. no. of weights.(1,3,9,27). 4.an algo for finding stuck at '0' in a given ckt. etc there were totally 10 question.
In Technical, question was focused on basics of network analysis (RC circuits), question on State machine, priority decoder, NAND-NOR implementation ,Op-Amp circuits, fault detection in a digital circuit, synchronous counter. One question was on current mirror, cmos inverter. there were totally 17 questions.
Duration: 130 minutes

Round: Technical Interview
Experience: In interview, they asked Network analysis, digital and VLSI. In VLSI, they asked about CMOS inverter, layout of inverter, various capacitors in a MOS and their effects. Why CMOS ?In digital, they asked T to D and D to T, fault detection in digital circuit, no. of 3-input Or gate required to make n input OR (n/2 if even or (n-1)/2 if odd).In NA, they were stick to RC circuits, what u can do with resister, capacitor and both. Analysis of voltage doubler ckt, and they made me solve some RC circuits..They asked of pipelining, its adv. as well as disadvantage . They also asked about programming skills ( sorting algo).

General Tips: My suggestion as a senior is be prepared for basics with in depth understanding and don't expect a question which u have seen before. But the fun is if your basic is strong, u can solve very easily.
