Hi, everybody!

I have several problems on Monte Carlo Analysis using OCEAN. Hope somebody can give me a hand. I really appreciate it.

The first problem is how to specify a seed when doing Monte Carlo analysis. I tried the command *monteCarlo( ?seed "2" ?numIters "3" ...)* and the Monte Carlo analysis ran successfully. But I am not sure whether it is right, because in the *OCEAN reference*, the *monteCarlo()* command do not have an argument like *?seed "2"*. By the way, what should be taken into consideration when choosing the value of the seed? Can I choose it arbitrarily?

The second problem is how to select and process the result of certain run of a Monte Carlo analysis. For example, after a Monte Carlo analysis is done, I get some files, such as *ac.ac *, *mc1-001_ac.ac *,* mc1-002_ac.ac *,* mc1-003_ac.ac *and so on. How can I select the result of certain run? Say, the result of the first iteration. I tried the command *selectResult( 'ac )* , and then *plot()* , but three curves were plotted corresponding to the three iterations of Monte Carlo analysis. Then I tried the command *selectResult( "ac-ac" )* , and then *plot()* , only the result of the nominal run before the Monte Carlo analysis was plotted.

The third problem is that can I run an analysis using the *input.scs*. If the answer is yes, how can I do it? It seems that the *input.scs* is similar to the *.sp* file in Hspice. So I guess it can be used to run an analysis. However, I tried the command *spectre input.scs *,and it ran successfully. But no result was plotted or saved. Even the psf file was not created.
