Phone questions: How to get the same rise and fall time for an inverter? What’s a LPF/HPF? What's the step response output of a LPF and HPF? What's Nyquist criterion? What's aliasing? What's impulse? Why do we measure impulse response? What is oversampling and why do we do it? What is FFT? IIR and FIR filters? What is quantization and quantization error? What's the difference between struct and a class? What is inheritance - explain. What did you model in real numbers? Did you find any bugs with your real number modeling? Onsite questions: Almost all the rounds started off with what I worked on. There was one round where they gave a problem to code and get it to compile - it was a difference detector which has input data coming in on every clock cycle. If data difference is +1 issue pos_signal; -1 issue neg_signal and others error_signal. They were unable to explain the requirements properly and left me confused on the specifics of the design given such a short time span. This round didn't go well. What's your dream job why? Asked about usage of randomization and classes. Not a single question on OVM/UVM though the job role specifies its heavy use in the role. What's the most complex sequence that you wrote? How would you call a testing done.
