pick out a single monte Carlo iteration in ocean?

[danmc]

Is there a simple way in ocean to pickout waveforms corresponding to
just 1 iteration of a monte carlo analysis?

Suppose I do a single iteration monteCarlo sim. Something like

analysis('tran ?stop 1u )
mciter=1
monteCarlo(?numIters 1 ?startIter mciter ?analysisVariation 'mismatch
?nomRun "no" )
monteRun()


Now if I do something like vdd=value(v("/VDD") 0) I actually get
another waveform because v("/VDD") is actually now a vector of
waveforms even though there is just 1 waveform in the vector. So if I
want the value of VDD at time 0 I actually need value(value(v("/VDD")
0) 0).

What I'd like is a way to globally say "I want the data from iteration
number `mciter' in all of the following commands" so I can continue to
use a large postprocessing script which I already have. It would be
very painful to replace every instance of v("/some/signal") with
value(v("/some/signal) 0) to pick out the actual waveform.

Any suggestions?

Thanks

value(v("/VDD") 'iteration 2)

for example - will get the waveform from the 2nd iteration (you need to ensure
that you've asked the monteCarlo to save the family data though).
