Output control for statistical analyses
Monte Carlo and sensitivity/worst-case analyses
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 data file for use by the waveform
analyzer. For Monte Carlo analyses, you can use the
performance analysis feature to produce histograms of
derived data.
Model parameter values reports
To produce a list of the model parameters actually used
for each run,
1 In the Simulation Settings dialog box, click the
Analysis tab.
2 From the Analysis type list, select an analysis type.
3 Under Options, select Monte Carlo/Worst Case.
4 Click the More Settings button.
5 Select List model parameter values.
6 Click OK to close the Simulation Settings dialog box.
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 midsize and large circuits, the List option can
produce a large output file.
