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. WebApr 5, 2024 · 1 Answer. This is pretty typical. Without details, the general outline is: Create and configure the agents just as you have described. The masters and slaves will be configured as active. A slave agent is typically a reactive agent that responds to stimulus from the DUT so in that case, sequence items in the slave driver will be initiated by ...

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. WebMay 11, 2024 · Hi, in UVM people tend to talk about agents as being passive, active, or reactive instead of "master" or "slave". 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 19, 2024 · If you receive the response in a different agent then there is no simple answer. It needs some more investigations. If the respinse is an interrupt you might add the interrupt signal/signals to the initializing interface. If there is no direct relationship you have to use horizontal synchronization. There are different approaches.

WebThe UVM has ACTIVE and INACTIVE agents where an INACTIVE agent is simply one that never drives a bus. What you want is sometimes called a slave sequence, or a responder. … 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.
