sequencer when doing sequence , not item

Recommended Posts

UVM userguide has following statement that I could not understand. Can anyone please elaborate?

Explanation while comparing to `do-ing item would help even more.

The sequencer does not schedule sequences but only items; therefore, when do-ing a sequence, no synchronization is done between the sequencer and the doing sequence or the done subsequence

`uvm_do(item) performs 4 tasks:

item create

item randomize

item start - synchronize with driver get_next_item

item finish - synchronize with driver item_done

`uvm_do(seq) performs 3 tasks:

seq create

seq randomize

seq start - this is the regular seq.start() the sequencer is not involved until the started sequence tries to do an item
