想请教一下：蒙特卡罗分析是什么？应该怎么做

It is compute simulated random possibility analyze.
  EX: you can generator a random input within your dynamic range and observe the
output distribution. [br]<p align=right><font color=red>+3 RD币</font></p>

Thank you very much. Your reply is very helpful for me.Could you introduce some tools for
me, which can do the Monte Carlo analysis. Or,can the smart-spice do this.

Matlab and spice should be able to do this in my opinion, sorry I have no idea of smart-spice, but since Monte Carlo analysis is one of basic computer simulation algorithm, I think most modern CAD/EDA tool should support this.[br]<p align=right><font color=red>+3 RD币</font></p>

应该是最坏情况分析。

通过该算法用较少的试验来模拟很多次随机试验 我是这样理解的 信号检测与估计里面讲过这东西 很有用的[br]<p align=right><font color=red>+1 RD币</font></p>

是容差分析,一种统计分析,是在给定的电路中元器件参数容差的情况下,计算电路输出的变量的均值和标准偏差.如果同时指定电路输出变量的容差,还可以计算出电路输出特性的合格率及合格率的偏差。[br]<p align=right><font color=red>+3 RD币</font></p>

Monte Carlos simulation is a worst case analysis considering the process and mismatch variations, basically. It can verify variations caused by the environment, temperature for example, or system parameters defined by designers. But as I have tested in my simulation, frequency variation is not included. Since it's a statistic analysis, for example 100 points can be run to see the distributions. A normal distribution is expected to be seen at the results.

A commonly used tool for MC anlaysis is Spectre or ADS.

请问：如何指定电路输出变量的容差，在哪里设置？
谢谢！

不无道理

Monte Carlo在统计分析意义上的重点是在于假设这个统计分析过程中的取样是完全随机的;

所对应的是某种能加速统计分析过程的"重要采样法",顾名思义,其中的采样是带有一些"偏见"的

呵呵，这个东西实际上也不怎么管用啊
