Analog Devices:---------------Profile : Design engineer (Digital)* 2 tech interviews 45 min each* FIFO depth calculation* Combinational circuit which generates a waveform (waveform given). (carfully arrange the gates so that we get the waveform of certain period)* How to improve the above circuit using sequentioal circuits? * Many questions from question paper they had for test (mainly those I messed and those I couldn't solve)* Panel was really helping, gave many clues to solve the problems* Problem based on clock sychronization?* Question based on asynchronous counter?* Make the same counter using synchronous counter (without using any gates)?* Sa-0 fault is there in a circuit with D-FF. Find the test pattenr to detect it* San based testing for a circuit for a given fault* Not a single question from resume* No formalities (self intro, resume check etc)* Gave a clear job description and whom they are looking for, in the beginning of interview itself Some more questions:* Design of Round Robin Arbiter* Design of FIFO and its implementation, synchronous and Asynchronous* Design of Sequential Circuit using D-F/F (Without using FSM)* Solve all the problems using intuition (not to use any standard method like K-map nor FSM Design)* Design of Pulse stretcher (must be optimum, without any glitches or change in period)* Find the longest and shortest path of a combinational circuit (Not the way in which we have done in VLSI Design course), but by possibly checking for all input test vectors
