WebDVCon Proceedings Archive 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.

Each agent contains a driver, a monitor, and a sequencer. An active agent has all three. A passive agent monitors, but does not drive.

WebApr 20, 2024 · UVC's are VIP that is specifically designed to integrate into a UVM testbench. An Agent is the hierarchy of classes consisting of the driver, monitor, and set of sequences used to simulate a particular interface to your DUT. An agent is passive when the driver is turned off or does not exist and only monitors signals from the DUT. 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. So at the end you may simply need to inline the execute code into your test.

WebReactive agents are software agents that carry out a simple task of retrieving pre-set behaviors similar to reflexes. Reactive agents do not maintain the internal state, unlike deliberative agents. Finding a difference between reactive agents and deliberative agents can be indistinct though.
