New function in ovm

In reply to dave_59:

Thnaks Dave,
Here my sample code is

`include"ovm.svh"
import ovm_pkg::*;
module top;
class test extends ovm_test;
 `ovm_component_utils(test);
 function new(string name="test",ovm_component parent =null);
  super.new(name,parent);
 endfunction
 function void build();
  ovm_report_info(get_full_name(),"Welcome to OVM",OVM_LOG);
 endfunction
 task run();
  #100ns;
 endtask
 test t1;
initial
  begin
   t1=new("t1",null);
  end
endmodule

here my log file is…
OVM_INFO @ 0: reporter [RNTST] Running test test…
OVM_INFO @ 0: ovm_test_top [ovm_test_top] Welcome to OVM
OVM_INFO @ 0: t1 [t1] Welcome to OVM

my questions are
1.How the hierarchy is display(differentiate ovm_test_top and t1)
2.I confused with (ovm_component parent) in new function
