plot Monte Carlo results as histogram

[Mobil]

Hi all,

After finish montecarlo simulation, the results can be plotted by
using ADE 'Monte Carlo Analysis' as a histogram, such as the x-array
is the analysis value (frequencies, gain, etc.) and y-array is the
numbers (if having 50 runs for a VCO circuit, there maybe a number of
45 runs of 2 GHz and 5 runs of 1.9 GHz ). Also the mean and standard
deviation values are shown in the graph.

Does anyone know how to write the scripts in netlist to present the
same function as print the histogram, mean and standard deviation?
Thank you.

Regs,

Mobil

Hi Mobil,

Function 'histogram' Plots a histogram of Monte Carlo data.
An example is:
monteExpr( "DCgain" ’ymax( vdb("vout") ) )
histogram( "DCgain" ?numBins 20 ?density t )

Please refer to the Cadence OCEAN Reference manual for more
information about this function. This manual is available in your IC
stream at: $CDSHOME/doc/oceanref/oceanref.pdf

Hope it helps !
Cheers,
Riad.

You can create the script from the monte carlo form: in menu session >
save script.

You may also find this sourcelink solution useful for getting mean and standard
deviation:

How can I calculate mean and standard deviation from monte carlo in OCEAN?

Thanks Riad and oliver, I've got it.
