Hi All,

I have to create a (Checker/Scoreboard) in SV for a packet based protocol and need a suggestion

Whether, I will use (Associative Array) or Queues for packet based protocols. I have to develop checker for PCI-Express.

Also please mention why ?
 

You use a queue when the order that the entries arrive in the queue are important, and you primarily access the front or back of the queue, rarely the elements in the middle. Accessing an element by its position in the queue is efficient, but the searching for a particular value in a queue is linear with its size. The ordering of associative arrays is user defined and independent of the order elements are created. Searching for a particular index value may be more important than any imposed ordering, and an associative array is design to make searching for an index value very efficient.
