Monte Carlo and sensitivity/worst-case analyses can generate
the following types of reports:
• model parameter values used for each run (that is, the values
with tolerances applied)
• waveforms from each run, as a function of specifying data
collection, or by specifying output variables in the analysis
set up
• summary of all the runs using a collating function
Output is saved to the Probe data file for use by the Probe
graphical waveform analyzer. For Monte Carlo analyses, Probe
offers a special facility through the performance analysis feature
to produce histograms of derived data.
Model Parameter Values Reports
The List option in the MC Options section of the Monte Carlo
or Worst Case dialog box produces a list of the model
parameters actually used for each run.
This list is written to the simulation output file at the beginning
of the run and contains the parameters for each device, as
opposed to the parameters for each .MODEL statement. This is
because devices can have different parameter values when using
a model statement containing a DEV tolerance.
Note that for medium and large circuits, the List option can
produce a large output file.
