错误 VCP2000“语法错误。意外的标记：初始。” “测试台.sv”50 7

Question

我无法在这里找到确切的错误，有人可以帮助我吗？

`include "uvm_macros.svh"
import uvm_pkg::*;

class my_driver extends uvm_driver;
    `uvm_component_utils(my_driver)

     function new(string path, uvm_component parent);
        super.new(path,parent);
     endfunction

  task run1();
    `uvm_info("DVR","INFO LEVEL",UVM_DEBUG);
    `uvm_warning("DVR", "WARNING LEVEL");
    `uvm_error("DVR","ERROR LEVEL");
    #10;
    `uvm_fatal("DVR","FATAL LEVEL");
  endtask

  task run2();
    `uvm_error("DVR1","Count of erros = 1");
    `uvm_error("DVR1","Count of erros = 2");
    `uvm_info("DVR1","simulation quit after 3 errors",UVM_DEBUG);
    `uvm_error("DVR1","Count of erros = 3");
  endtask

endclass

class my_environment extends uvm_env;
  `uvm_component_utils(my_environment)

  function new(string path, uvm_component parent);
    super.new(path,parent);
  endfunction
  
  initial 
    begin
      my_driver my_dvr_obj;
      my_dvr_obj = new("DVR",null);
      my_dvr_obj.run1();

      my_driver my_dvr_obj_new;
      my_dvr_obj_new = new("DVR1",null);
      my_dvr_obj_new.set_report_max_quit_count(3);
      my_dvr_obj_new.run2();
    end

  task my_task();
    `uvm_info("MY_ENV","Verbosity level is UVM_DEBUG in Environment",UVM_DEBUG);
  endtask

endclass

module tb;
  initial begin
    my_environment new_env_obj;
    new_env_obj = new("MY_ENV",null);`your text`
    new_env_obj.set_report_verbosity_level_hier(UVM_DEBUG);
    new_env_obj.my_task();
  end
endmodule

我正在尝试将 my_environment 的详细程度更改为 UVM_DEBUG。

在

initial

内使用

class

关键字是非法的。 当我尝试使用 Cadence 模拟器编译您的代码时，我收到一条更有帮助的错误消息：

xmvlog: *E,DECINM : Declaration is only valid within a module, interface, or a program block.

当您不明白错误消息时，您可以尝试在 EDA Playground 上的其他模拟器上编译您的代码。

您可以将

initial

块中的代码添加到

new

函数中。
