UVM Reactive Stimulus Techniques

WebA reactive agent basically starts an infinite sequence that just waits for the DUT to trigger a request to it and then it just answers. A reactive agent never initiates traffic, but just responds to it. Have a look at this thread for more info: http://forums.accellera.org/topic/563-implementing-reactive-slave-agent-in-uvm/ WebThere are four basic reporting functions that can be used with different verbosity levels. where * can be either info, error, warning, fatal. UVM has six levels of verbosity with each one represented by an integer. Note that the VERBOSITY_LEVEL is only required for uvm_report_info. Usage of uvm_report_fatal will exit the simulation. how food production impacts the environment

WebJul 5, 2024 · The UVM register layer acts similarly by modeling and abstracting registers of a design. It attempts to mirror the design registers by creating a model in the verification testbench. By applying stimulus to the register model, the actual design registers will exhibit the changes applied by the stimulus. WebApr 7, 2024 · But even worse, clocking block events are intended to be triggered by events in the active region. If you try generating a clock in the reactive region by creating a UVM clock driving agent, that can lead to races with input sampling.

WebThe simplest option is to execute the transaction directly on a sequencer using uvm_sequencer_base::execute_item (uvm_sequence_item). But you can't get the response back as the execute method uses a temporary sequence.
