UVM Components

UVM Methodology page dives deep into various UVM components, including:

UVM Agent

  • Purpose: Acts as an interface between the testbench and the DUT (Device Under Test).
  • Components: Typically includes a driver, monitor, and sequencer.
  • Role: Coordinates the communication and ensures the proper flow of data between the testbench and DUT.

UVM Driver

  • Purpose: Stimulates the DUT by driving signals.
  • Role: Reads sequences from the sequencer and converts them into signal-level transactions for the DUT.

UVM Monitor

  • Purpose: Observes the DUT’s outputs.
  • Role: Captures and analyzes data from the DUT, sending it to the scoreboard or other analysis components for verification.

UVM Sequencer

  • Purpose: Controls the order of stimulus sequences sent to the driver.
  • Role: Manages the flow of sequences, ensuring they are executed in the correct order and timing.

UVM Sequence

  • Purpose: Defines a series of transactions for the driver to execute.
  • Role: Specifies the data and control flow for simulation, effectively driving the test scenarios.

UVM Scoreboard

  • Purpose: Compares expected and actual outputs.
  • Role: Tracks and verifies the DUT’s behavior, ensuring it matches the design specifications.

UVM Environment

  • Purpose: Encapsulates all components required for verification.
  • Role: Acts as a container for agents, drivers, monitors, and other verification components, organizing them into a coherent testbench.

UVM Test

  • Purpose: Top-level component that configures and controls the verification environment.
  • Role: Defines the overall verification plan and initiates the execution of sequences.

UVM Configuration Database

  • Purpose: Stores and manages configuration settings for the verification environment.
  • Role: Ensures consistency and accessibility of configuration data across all components.

UVM Factory

  • Purpose: Creates and registers UVM components.
  • Role: Enables dynamic creation and configuration of verification components at runtime.
