Essentially, the job of the sequencer is to control the flow of sequences to the driver. In the next section, we will explore a few ways to generate sequences.

Sequences

Now is the perfect time to review graphically the components we have built thus far.

Figure 4: Sequences

We have our data packet, the interface, a driver, and a sequencer. Now we need to learn how to create sequences using the data packet. A sequence specifies one or more sequence items to be sent to the driver; in other words, one or more packets to be driven. Typically, sequence classes are derived from uvm_sequence and parameterized with your uvm_sequence_item type. For example:
