uvm macro (常用的）[uvm_info]

`uvm_info(1,2,3)

1:ID
2:MSG
3:VERBOSITY
如果VERBOSITY级别低于reporter组件定义的级别，就会调用uvm_report_info



举例：
-->    `uvm_info("DRV_RUN",{req.sprint()},UVM_HIGH)
-->    `uvm_info("MY_INFO",$sformatf("pval:%0d",val),UVM_LOW)

也可以自行定制：
`uvm_info_begin("MYID","this is a message for test...",UVM_LOW)
    `uvm_message_add_tag("author”,ZHUHAI）

    `uvm_message_add_object(my_obj)

`uvm_info_end
