How to use Avalon-MM Master BFM?

Hello, all.

//Console messaging level
`define VERBOSITY VERBOSITY_INFO
//BFM hierachy
`define CLK_BFM     top.tb.clock_source
`define RST_BFM     top.tb.reset_source

`define CONDUIT_BFM top.tb.conduit_bfm

  event start_test;
  event end_test;
  
  //----------------------------------------------------------------------------------
  // Set verbosity before the test starts
  // Qsys-generated testbench activates clock and reset BMFs
  //----------------------------------------------------------------------------------
  initial begin
	set_verbosity(`VERBOSITY);
	
	// initialize BFMS
	`MM_MASTER.init();
  end
  
  //----------------------------------------------------------------------------------
  // Main test block
  //----------------------------------------------------------------------------------
  initial begin
	// wait for reset inactive
	wait(`RST_BFM.reset == 1);
		-> start_test;
  end
  
  initial begin

	`MM_MASTER.set_command_address(16'h0);
	`MM_MASTER.set_command_idle(2,0);

	`MM_MASTER.set_command_data(32'h0,0);
