It is very common to include two identical agents in a UVM testbench. One uses a default-active sequencer-driver pair and the other sets an is_active bit to uvm_passive to disable the sequencer-driver pair. Both monitors are identical and sample the VIF signals to re-assemble a standard transaction that is then sent through the monitor-analysis port to the agent-analysis port and on to both sides of the scoreboard. Since the analysis port can write to multiple analysis export/imp-ports, when building simple UVM testbenches, why not just use one active agent that drives both sides of the scoreboard and discard the passive agent?
