在SystemVerilog中,要打印UVM Objection的内容,你可以使用`uvm_report_object`函数配合适当的上下文信息。首先,你需要创建一个`uvm_message_port`来接收和发送消息,然后使用`uvm_report_objection`来记录Objection。当需要查看Objection内容时,可以像这样操作:
```systemverilog
class my_uvm_component extends uvm_component;
uvm_message_port#(uvm_objection) m_objection_port;
// 在组件初始化时打开报告端口
function new(string name = "my_uvm_component");
super.new(name);
m_objection_port = m_objection_port.type_id::create("objection_port", this);
endfunction
task run();
uvm_objection objection;
// 创建并设置Objection
objection = new("My Objection");
objection.set_info("Custom info", "This is the object details");
// 发送Objection
m_objection_port.send(objection);
forever begin
if (m_objection_port.any()) begin
uvm_report_object(m_objection_port.get(), UVM_INFO, "Objection received:", UVM_NONE);
end
else
wait(1ns);
end
endtask
endclass
```
当你运行上述代码,在捕获到Objection后,会通过`uvm_report_object`打印出其名称、自定义的信息以及额外的详细内容。
