scharmin Posted November 11, 2011 Report Share Posted November 11, 2011 I am using RAL in my UVM testbench. I have a typical microprocessor memory mapped system. And I have modeled all memories and registers using the UVM RAL classes. For this I needed to provide a "RAL adapter", a class that extends uvm_reg_adapter. In this class I provided an implementation for the methods "reg2bus" and "bus2reg" to translate the RAL transaction into a transaction that my BFM can execute. Here is the problem: My microprocessor will execute burst transactions. So when read data is returned (or write data is written) a whole array of data can be written/read. However, the adapter class methods "reg2bus" and "bus2reg" take an argument that's a "struct" and the data in this struct is a single-beat 2-state data property, whereas I need to be an array of 4-states. Furthermore, since this argument is a struct, not a class, I cannot use factory overrides to possibly replace the transaction with another class type that I define. Any suggestions?
