disable timeout_block ; end join_none endtaskdisable fork可以停止从当前线程中衍生出来的所有子线程。initial begin check_trans (tro) ; //线程0 //创建一个线程来限制disable fork的作用范围 fork //线程1 begin check_trans(tr1); //线程2 fork //线程3 check_trans(tr2); //线程4 join //停止线...
也就是说disable timeout_block会停止所有标签为timeout_block的块内的线程,时间最短的线程结束时调用的disable timeout_block也停止了另外两个Transaction实例所起的线程,和运行结果一致。 在这个例子中,要想达到我想要的结果,应当将task check_trans()的disable语句修改为disable fork: taskcheck_trans(Transactiontr...
