Create sequence item using factory

UVM_learner6 · September 5, 2019, 7:05pm

To use a sequence item in a sequence Mentor, A Siemens Business recommends using the factory to create the sequence item, the start_item() task to arbitrate with the sequencer and the finish_item() task to send the randomized/prepared sequence item to the driver connected to the sequencer.

Mentor, A Siemens Business does not recommend using the UVM sequence macros. These macros include the 18 macros which all begin with `uvm_do,` uvm_send, `uvm_create,` uvm_rand_send.

Based on the coding guidelines above, `uvm_create is not recommended. So, how can we use factory to create sequence item? Is it using ::type_id::create command? Should this be done in the body task of the sequence, if not, where else?

Thanks.
