These characterize elementary elements throughout the Common Verification Methodology (UVM) simulation atmosphere. One gives 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 take a look at sequence and related configuration knowledge that drives the verification course of. As an illustration, the take a look at sequence to confirm the performance of an arbiter could be launched from this container.
Their use is crucial for managing complexity and enabling reusability in verification environments. They set up a transparent organizational construction, making it simpler to navigate and debug complicated testbenches. Traditionally, UVM’s adoption of a hierarchical part construction rooted at these factors represented a major development over ad-hoc verification approaches, facilitating modularity and parallel growth.
