When I was preparing for a customer presentation on UVM RAL, I could not understand what the UVM base class library is saying about updating the values of desired value and the mirror value registers. Also I felt that the terms used are not exactly reflecting the intent. After spending some time, I came up with a table which will help to understand the behavior when the register model APIs are called. Before I introduce the table, let us take a look at the process about how to create the register model. I would describe that in 3 steps.
- Creating the register format specification
- Converting the specification into UVM register model
- Using the register model.
