帮我生成uvm base sequence 基本框架代码

Sure, I can help you generate the UVM base sequence basic framework code. However, I am not able to understand your programming language preference or specific requirements. Can you please provide me more details or specifications?

uvm_sequencer里面有sequence的成员变量吗

在UVM Sequencer（Sequence Verifier）框架中，`uvm_sequence` 类本身并不直接包含成员变量，而是通过继承自`uvm_base_sequencer` 和实现特定功能的`uvm_sequencer #(T)`模板来管理和控制序列的行为。然而，你可以自定义创建的`uvm_sequence` 实例（比如`my_sequence`）来添加私有的或公开的成员变量。

在自定义序列类中，你可能会有以下类型的变量：

1. **公共变量** (`public` 或 `parameter`)：这些变量可以在任何关联到该序列的地方访问，例如`uvm_sequence_item`，用于记录状态信息、计数器等。

2. **私有变量** (`private`): 这些只在序列类内部可见，用于存储私有数据或作为内部逻辑的一部分。

3. **保护级变量** (`protected`): 可供派生类访问，提供了一定程度的封装。

4. **实例变量** (`instance_var`): 可能包括一些状态机状态或其他需要在整个序列过程中跟踪的数据。

class my_sequence extends uvm_sequence#(transaction_type) {
   protected int current_state; // 保护级变量
   private rand bit [8];        // 私有变量

   public rand int counter;      // 公共随机数生成器变量

   function new(string name = "my_sequence");
      super.new(name);
      // 更多的初始化和成员变量声明
   endfunction

   task body();
      repeat (...) begin
         sequence_item item;
         get_next(item);
         // 序列体处理...
         if (item.end_of_sequence) return;
      end
   endtask
}
