WebMar 31, 2011 · I see several possible solutions: 1.) Create a sequence (like the interrupt sequence) that would be created inside the sequencer and would get triggered by an event. 2.) Modify the Agent's driver so that it could be configured as either a Master or Slave. 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 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 ...

One passive agent to capture transactions at the output of the encoder block. One reactive agent to send transactions to the input of the decoder block. 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.

How does a UVM sequence change the transactions based on …

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.
