Hi Cgales,

Thanks for the comment. In the below code, whatever randomized in trans_seq will be passed to write_seq right. But, while executing this code, I observed that, write_seq.write_data and write_seq.address has different data.

Note : Both are started with p_sequencer.

class write_seq extends uvm_sequence #(uvm_sequence_item);
  `uvm_object_utils(write_seq)
  `uvm_declare_p_sequencer(virtual_sequencer) 
   rand bit[31:0]   write_data;
   rand bit[31:0]   address;
endclass : write_seq

class trans_seq extends uvm_sequence #(uvm_sequence_item);
  `uvm_object_utils(trans_seq)
  `uvm_declare_p_sequencer(virtual_sequencer) 

  function new(string name = "trans_seq");
    super.new(name);
  endfunction : new

   rand bit[31:0]   write_data;
   rand bit[31:0]   address; 
 
   write_seq  wr_seq;

   extern virtual task body();
endclass : trans_seq

task trans_seq::body();
    wr_seq = write_seq::type_id::create("wr_seq"); 
    wr_seq.randomize with {write_data == this.write_data;
                           address    == this.address;};
    wr_seq.start(p_sequencer);
endtask : body
