如何在SystemVerilog中将调试消息传递给宏

module my_module;
  initial begin
    $display("Hello, World!");
  end
endmodule

module my_module;
  initial begin
    $write("Hello, ");
    $write("World!");
  end
endmodule

`define DEBUG_ENABLED

module my_module;
  initial begin
    `ifdef DEBUG_ENABLED
      $display("Debug message");
    `endif
  end
endmodule
