Section goal

Interviewers draw monitor → scoreboard/coverage arrows constantly. You must name port types, connect_phase wiring, and when to use FIFO vs analysis push.

Mechanism to narrate

• analysis_port initiates write() on connected export

• uvm_subscriber provides analysis_export + write(txn)

• Fanout: one port → multiple exports (broadcast)

Key takeaways

• Draw arrows before writing class keywords.
