Xilinx Senior Design Engineer interview questions

Sv, UVM, ARM architecure, Axi protocol

Most difficult was how would you write a script to calculate the latency of a PCIE bus given a data base of several transactions, and their completions. An easier one that was asked that was unexpected, given I am more HW is: Write a function to detect a one-hot encoded state variable. I sort of bombed it at the interview, but looked into the solution in detail after the interview.
