AXI Protocol based Interview Questions

Hi everyone,

To support those preparing for hardware verification and design roles or for engineers working with the protocol daily, I’ve compiled a curated list of AXI Protocol Interview Questions.

To help you navigate the content effectively, I have categorized the questions into three levels:

Basic Level:

  1. What are the key features of the AXI protocol?
  2. Why does AXI have 5 channels? Name them and explain why they are separate?
  3. Why does the Read operation only have 2 channels while Write has 3?
  4. Explain the VALID/READY handshake. What are the three possible scenarios for these signals?
  5. Define "Beat", "Transfer", and "Burst"?
  6. What are the three burst types in AXI? (FIXED, INCR, WRAP). Give a real-world use case for each ?
  7. What are the four AXI response types? Explain the scenario when respective response type is received ?
  8. Can AXI read and write happen simultaneously?
  9. Can address and data phases overlap?
  10. Why there is no read response channel in AXI ? 
  11. How do you check handshake correctness?
  12. In AXI4, can a slave send a Write Response (BVALID) before the master has finished sending all the data beats (WVALID/WLAST)?
