what is your research area?
First interview - I was asked to write pseudo code for memory allocation (like malloc/free). Second interview - I was asked to describe verification environment for a FIFO, considering sync/async. And to write a UVM monitor.
If you had to choose between two vacuums, same price, what would be some of the things you would consider?
what is a uvm agent?
Write a scoreboard in SV or UVM for simple alu where there is an 8 bit input that is changing value every clock cycle and the output should be equal to sum of previous 5 inputs.
