                                    UVM RAL Adapter

       With the UVM Register model, we do design register access, i.e WRITE to the design register or READ from the design register by calling RAL methods. Finally, these transactions have to be placed to design bus, this will be done by RAL component Adapter.

       The RAL adapter acts as a converter between the RAL model and Interface. It converts transactions of RAL methods to Interface/Bus transactions.

• The Adapter converts between register model read, write methods and the interface-specific transactions
• The transaction adapter is implemented by extending the uvm_reg_adapter class and implementing the reg2bus() and bus2reg() methods

一、UVM RAL reg2bus

• reg2bus method converts the RAL transactions to Interface (bus) transactions

二、UVM RAL bus2reg

• bus2reg method converts the Interface (bus) transactions to RAL transactions
