Question

我有TCL文件，并且每次修改代码的某些部分面对不同的模拟时间在NAM运行，我需要它是1000秒，但模拟似乎不到这个时间，我应该怎么做？如果我选择128的数据包大小更好或不？如果我有更大的数据包大小有什么区别？

Answer 1

»»我需要1000秒......««

您在帖子中显示的文件已停止= 50。

并且“停止”是最长时间。

当模拟具有例如文件中“工作”5秒钟：

无论你设定多长时间，都会在5秒后停止。

..............

设置val（停止）50; #stop是停止模拟的时间，如果它仍在运行。

..............

在NAM的模拟和分组差异的大小期间，模拟时间不相同
