Here are features of RAL model. We will see their usage later in the article.

1. Abstract physical location of the registers and the fields
2. Flexibility in switching front door and backdoor access
3. Content is mirrored in external data structure
4. Independence of test cases and register specification
5. Predefined register types

Advanteges of VMM RAL :

1. VMM RAL provides automatic creation of high level abstraction model for register map of DUT by just providing register map file.
2. Provides automatic generating of coverage bins.
3. Provides back door access for registers and memory.
4. Easy to integrate in current VMM base verification environment.
5. RAL Model will be automatically updated when ever register in memory is read or
written.
6. Comprehensive Pre-defined tests available.
7. Supports design with multiple physical interface, as well as registers and memory shared
across different interfaces.
8. Supports memories to be addressed as virtual register and virtual fields.
