Write to Register Model based on Physical address

UVM
1

I have a specific requirement where I need to write to memory or register based on physical address. I have handle to register model and need to write to physical address using register model.
I do not know register name and all I have is physical address and reg model handle.
I will get a physical address and need to write using write method in RAL.
Do I get register map and find register name from map (based on physical address) and then use register_name.write()?

Is their any easy way to handle this?

Hi,

You can use get the register handle first with following code and once you have handle of reg than you can perform any operations.

uvm_reg regs[$];
uvm_reg reg;
int physical_address = 'h99AE;  // This should be base address of map + register address
//get all registers stored in map
ral_model.default_map.get_registers(regs)

//checking individual register address with expected physical_address
foreach(regs[i])
begin
  if(regs[i].get_address(ral_model.default_map) == physical_address)
  begin
    reg = regs[i];
    break;
  end
end
//perform register operation with 'reg' handle
// reg.write or reg.read
