In reply to yasaswi93:

I agree with Dave. I think you are getting confused between these two

  1. out of order transactions verification in a scoreboard
  2. sequence item arbitration by the sequencer
    For 1 like you mentioned we use associative arrays and queues and all transactions generally have an id field.
    For 2 as far I understand sequencer will handle the id. You don’t have to worry about it.

Thank you! For 1, the transactions will generally have an id field. But I believe there must be some protocols that won’t have unique id field. How is that handled? One such could be packet processors etc.
