Re: required number of points for MonteCarlo simulation
Thanks for you answer. But how can i know that i have enough samples. For example i simulate a operational amplifier and look on offset voltage. If i have 100 point for monte carlo simulation, i have correct result? Or i should take 1000/2000 to plot correct curve of distribution?

Re: required number of points for MonteCarlo simulation
The number of points needed is determined by the statistical confidence level you want.
There is no "correct result" in statistics, only a good result.
For a better understanding, you need a basic understanding of statistics.
Looking at the mean and standard deviation of the results will give you an idea of how good your MonteCarlo data is in determining the expected deviation in a production run.Zapper

Re: required number of points for MonteCarlo simulation
100 points usually for me gave a pretty good standard deviation for an OPAmp offset voltage, sometimes 30 is enough if the design is in an initial state, not bad, but to see the contribution percentage of the devices to the offset an 1000 points are required at least. These are just kind of thumb rules, but above answers covered this topic.
