1 states following : “By default, responses from the driver are retrieved in the sequence by calling get_response. In the previous article, we saw how a UVM driver gets the next item by the calling get_next_item method, and how it informs the sequencer that the current item is done Although this is the preferred way for driver-sequencer communications, UVM also gives us an alternative for a more complex implement ents for which a license may be required by an Accellera standard or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.
