UVM Register Modeling for Verification
Build practical UVM register models from specifications, integrate them with APB-based environments, run built-in checks, create user-defined register stimulus, and use front-door, back-door, update, mirror, predict, peek, and poke operations for efficient DUT verification.

Description
UVM register modeling provides a practical abstraction layer for verifying register and memory behavior in a design under test. Instead of manually writing bus-level accesses and separate expected-value checks for every register, the register model captures addresses, widths, reset values, fields, access policies, memory regions, address maps, and expected state. This makes register verification more readable, repeatable, and reusable across environments that use different interface protocols. A memory controller with an APB interface, a 4K memory block, mode registers, a status register, and access counters provides a focused technical target. The register model represents ordinary read/write storage, read-only status behavior, memory access, counter updates, and side effects caused by register operations. Desired values define intended configuration, while mirrored values represent the expected DUT state. These model values support automated checking, model-driven updates, and synchronization between the DUT and the register reference model. Automatic generation reduces the risk of hand-coded UVM register models. Register specifications can be captured in IP-XACT XML, spreadshe...
