如何在每个寄存器映射访问中添加额外的uvm_reg写操作？

class my_reg_access extends uvm_reg_access_block;
  // 重写do_write方法
  virtual function void do_write(uvm_reg rg, uvm_reg_data_t value, uvm_path_e path = UVM_DEFAULT_PATH, uvm_reg_map map = null);
    // 调用父类的do_write方法
    super.do_write(rg, value, path, map);
    
    // 添加额外的写操作
    // ...
  endfunction
endclass

// 在测试环境中使用自定义的寄存器访问类
class my_test extends uvm_test;
  my_reg_access reg_access;
  
  function new(string name, uvm_component parent);
    super.new(name, parent);
    reg_access = new();
  endfunction
  
  virtual function void build_phase(uvm_phase phase);
    super.build_phase(phase);
    // 设置寄存器访问类
    uvm_config_db#(uvm_reg_access_block)::set(this, "*", "reg_access", reg_access);
  endfunction
  
  // 测试代码
  // ...
endclass
