These symbolize elementary elements throughout the Common Verification Methodology (UVM) simulation setting. One offers a root for the UVM object hierarchy, serving because the implicit top-level module the place all UVM elements are instantiated. The opposite extends this root, serving because the container for the check sequence and related configuration knowledge that drives the verification course of. For example, the check sequence to confirm the performance of an arbiter may be launched from this container.
Their use is important for managing complexity and enabling reusability in verification environments. They set up a transparent organizational construction, making it simpler to navigate and debug advanced testbenches. Traditionally, UVM’s adoption of a hierarchical part construction rooted at these factors represented a big development over ad-hoc verification approaches, facilitating modularity and parallel growth.
