uvm_reg_cbs——寄存器模型（十六）

当你完成寄存器模型的时候，你就会想到给后来的人一个接口，给他更多的扩展，让他做更多的事，一般而言，只有做VIP时，会想到做callbacks.

typedef class uvm_reg;
typedef class uvm_mem;
typedef class uvm_reg_backdoor;

//------------------------------------------------------------------------------
// Title: Register Callbacks
//
// This section defines the base class used for all register callback
// extensions. It also includes pre-defined callback extensions for use on
// read-only and write-only registers.
//------------------------------------------------------------------------------

//------------------------------------------------------------------------------
// Class: uvm_reg_cbs
//
// Facade class for field, register, memory and backdoor
// access callback methods.
//------------------------------------------------------------------------------

virtual class uvm_reg_cbs extends uvm_callback;

   function new(string name = "uvm_reg_cbs");
      super.new(name);
   endfunction
