In UVM, sequences can provide a wealth of functionality beyond initiating stimulus on a particular interface. Often designs require the verification environment to respond to traffic from the DUT, and sequences can model this behavior as well. By modeling responders through the use of Slave Sequences, UVM enhances reuse by encapsulating the functionality in sequences that can be controlled from the test, without having to replace the agent connected to the DUT. In this webinar, we will walk through the mechanics of setting up and executing Slave Sequences in a responder. We will also walk through modeling an interrupt sequence and show how to have interrupt sequences running in conjunction with other stimulus sequences.
