Hello All,

I want to handle multiple outstanding transaction in driver class, so i can not use get_next_item and item_done methods in the driver because i can not handle another transaction until item_done is not done for first transaction, so is there any other way or method that UVM driver class support to do this? I know some what about the get and put method but in this case sequence writer always need to wait for response from the driver.

Thanks in Advance!

What do you mean with 'outstanding tansaction? Dou you have a pipelined protocol in the driver?
It is common taht you have more than 1 transaction generated by the sequencer and the get_next_item/item_done is processing step-by-step.

Yes, It’s pipelined protocol (AXI3/4). so, I want to initiate (drive) second address before transfer competition for fist address.
