327 ic design engineer interview questions shared by candidates
-MOS operating regions -PLL locking mechanisms -impedance of cross coupled diff pair
what you are looking for for next job
How do you create a voltage higher than supply voltage in your circuit?
Questions on On chip variation and what causes them. Was asked how I'd model them. i mentioned timing derates -which are a very old technique. Was asked if i worked with AOCV models. Was asked few questions on clock jitter
Design a synch FIFO. Was asked a simplified version. Was asked to assume depth of FIFO was 4 and width was 32. He was just looking for how and when I'd update the memory buffer and the control logic for the free and avail Was given a verilog module and asked to figure out what it was doing. Noticed that it was a round robin-ish arbiter. Later was asked if there was any case where starvation (live lock) was possible. It became clear as I was working thru the waveforms there was a specific case where the arbiter can starve any of the requests. Then I was asked to fix the code. Also I was asked how would we catch issue like this. I mentioned that Formal Prop Verif tools are the best vehicles to find bugs on such designs
Describe your current role. Send a pulse from one clock to another clock. How to send data from one clock domain to another. Minimum sizing of an async FIFO
project on which i worked
mostly questions from resume and typical new grad questions
1. Introduction of your background (Fresh Graduate ? Experienced ? ) 2 What project you have done related to IC design ? 3 Elaborate more on the project (Not only description but also detailed technical question will be asked ) 4 Hand draw some circuit and answer any question they may have (Purpose ? Pros and Cons ? Gain ? )
