6.is_on:表明reset以后事件是否被触发; 7.is_off:表明事件是否被触发或reset; 8.reset:reset事件到off状态; 9.cancel:减少事件上等待者的数量; 10.get_num_waiters:返回等待事件的进程数; 11.wait_trigger_data:此方法调用<uvm_event_base::wait_trigger>然后调用<get_trigger_data>; 12.wait_ptrigger_dat...
接下来和systemverlog中event达成同步的操作一样了,在一个进程中触发->,另外一个进程中等待触发wait (event.triggered) or @event。 在uvm_event中,触发的方式是uvm_event.trigger();而等待出发的方式是wait_ptrigger()电平触发)or wait_trigger()上升沿触发(与event的两种等待方式对应)。 uvm_event 相较于even...
首先,需要先看看uvm_event_base这个类,其实本质就是个object,只不过包含了几个变量,on、num_waiters代表wait_trigger的数量,m_event就是sv的event数据类型啦,此外还有callback函数的队列。 virtualclassuvm_event_baseextendsuvm_object;protectedbiton;protectedintnum_waiters;protectedeventm_event;protecteduvm_event_ca...
