1.让scoreboard 主动接收，使用FIFO。

2.实现图：

3.在agent和 scoreboard之间添加一个uvm_analysis_fifo。FIFO的本质是一块缓存加连个IMP。scoreboard 使用blocking_get_port 端口：

`ifndef MY_SCOREBOARD__SV
`define MY_SCOREBOARD__SV
class my_scoreboard extends uvm_scoreboard;
   my_transaction  expect_queue[$];
   uvm_blocking_get_port #(my_transaction)  exp_port;
   uvm_blocking_get_port #(my_transaction)  act_port;
   `uvm_component_utils(my_scoreboard)

   extern function new(string name, uvm_component parent = null);
   extern virtual function void build_phase(uvm_phase phase);
   extern virtual task main_phase(uvm_phase phase);
endclass 

function my_scoreboard::new(string name, uvm_component parent = null);
   super.new(name, parent);
endfunction 

function void my_scoreboard::build_phase(uvm_phase phase);
   super.build_phase(phase);
   exp_port = new("exp_port", this);
   act_port = new(
