UVM: Registers/Register Model Overview
In order to be able to use the UVM register model effectively, it is important to have a mental model of how it is structured in order to be able to find your way around it.
The register model is implemented using five main building blocks - the register field; the register; the memory; the register block; and the register map. The register field models a collection of bits that are associated with a function within a register. A field will have a width and a bit offset position within the register. A field can have different access modes such as read/write, read only or write only. A register contains one or more fields. A register block corresponds to a hardware block and contains one or more registers. A register block also contains one or more register maps.
