How to print RAL model with details?

In reply to shreebamnikar:

What kind of details do you mean?
Normally you have all the details in your register spec. And you use the spec for generating the RAL model.

First try would be ral_model.print();

This would print all details that have been provided via field utils

You need to explain more on what details you are looking for to seek more help.

Yes, provided you use field macros, see an example below:


   class vl_data extends uvm_reg;
      `uvm_object_utils(vl_data)

      rand uvm_reg_field data;
      // More code below
   endclass : vl_data
   //--------------------------------------------------------------------
   // vl_ctrl
   //--------------------------------------------------------------------
   class vl_ctrl extends uvm_reg;
      `uvm_object_utils(vl_ctrl)

      rand uvm_reg_field ctrl;
      // More code below
   endclass : vl_ctrl
   

task vlb_reg_model_test::main_phase(uvm_phase phase);
  int res;
  phase.raise_objection(this);
  `uvm_info(get_name(),
    $sformatf("Printing REG model "),UVM_LOW)
  this.vlb_reg_block_1 = vlb_reg_block::type_id::create("vlb_reg_block_1");
  this.vlb_reg_block_1.build();
  this.vlb_reg_block_1.print();

Output:
