UVM agent

Concept

A UVM agent is a reusable verification component used to connect a virtual sequence to a specific DUT interface or sub-interface. In the cited VPU verification environment, each agent contained a sequencer, driver, and monitor connected to a virtual interface; the driver applied transactions to the DUT sub-interface, while the monitor observed interface state and returned transactions for sequencing and checking.

Overview

A UVM agent is a component used inside a Universal Verification Methodology verification environment to encapsulate stimulus generation and observation for a specific DUT interface or sub-interface. In the referenced VPU verification environment, the design exposed several semi-independent sub-interfaces, so the verification team created one agent for each specific sub-interface.
