dmq0420 Posted November 21, 2012 Report Share Posted November 21, 2012 Does anyone meet this UVM_ERROR? The full log infomation is: UVM_ERROR @ 89000: did not produce an item within an NBA delay. Sequences should not consume time between calls to start_item and finish_item. Returning null item. UVM_ERROR @ 90000: get_next_item/try_next_item called twice without item_done or get in between In fact, the test not always failed. But only failed for some seeds and the error message is always like above when failed. In my sequence, I'm using lots of "fork join_any" and "fork join". In the top sequence, it instantiate several sub-sequences and there are many "fork" in each sequences. What I want to know is why UVM report such error? And how to debug this error?
