ahb slave的UVM验证环境中的driver和monitor详细代码

由于AHB Slave的UVM验证环境中的driver和monitor的详细代码因人而异，这里提供一个基本的参考实现。

`ahb_slave_driver.svh`：

class ahb_slave_driver extends uvm_driver #(ahb_slave_seq);

  `uvm_component_utils(ahb_slave_driver)

  ahb_slave_if ahb_if;

  virtual function void build_phase(uvm_phase phase);
    super.build_phase(phase);

    if(!uvm_config_db #(ahb_slave_if)::get(this, "", "ahb_if", ahb_if))
      `uvm_fatal("NO_AHB_SLAVE_IF", {"Cannot get AHB slave interface"});

    `uvm_info("ahb_slave_driver", "Build AHB slave driver", UVM_NONE)
  endfunction

  virtual task run_phase(uvm_phase phase);
    ahb_slave_seq req;

    forever begin
      seq_item_port.get_next_item(req);
      ahb_if.write_addr(req.addr);
      ahb_if.write_data(req.data);
      ahb_if.write(req.cmd);
      seq_item_port.item_done();
    end
  endtask

endclass

`ahb_slave_monitor.svh`：

class ahb_slave_monitor extends uvm_monitor;

  `uvm_component_utils(ahb_slave_monitor)

  ahb_slave_if ahb_if;
  uvm_analysis_port #(ahb_slave_seq) seq_item_port;

  virtual function void build_phase(uvm_phase phase);
    super.build_phase(phase);

    if(!uvm_config_db #(ahb_slave_if)::get(this, "", "ahb_if", ahb_if))
      `uvm_fatal("NO_AHB_SLAVE_IF", {"Cannot get AHB slave interface"});

    if(!uvm_config_db #(uvm_analysis_port #(ahb_slave_seq))::get(this, "", "seq_item_port", seq_item_port))
      `uvm_fatal("NO_SEQ_ITEM_PORT", {"Cannot get sequence item port"});

    `uvm_info("ahb_slave_monitor", "Build AHB slave monitor", UVM_NONE)
  endfunction

  virtual task run_phase(uvm_phase phase);
    ahb_slave_seq rsp;

    forever begin
      if(ahb_if.hready) begin
        rsp.addr = ahb_if.read_addr();
        rsp.data = ahb_if.read_data();
        rsp.resp = ahb_if.read_resp();
        seq_item_port.write(rsp);
      end
      #1;
    end
  endtask

endclass

这里的代码实现了一个简单的AHB Slave验证环境，其中`ahb_slave_driver`负责将测试用例中的数据写入AHB从设备，`ahb_slave_monitor`则负责监听AHB总线上的读写请求，并将响应数据传递给测试用例。在实际应用中，需要根据实际情况对代码进行适当修改和扩展。
