PSpice User Guide Monte Carlo and sensitivity (worst-case) analyses October 2019 557 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. 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. For information about performance analysis, see RLC filter example on page 513. For information about histograms, see Creating histograms on page 584. 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 in the output file of each run. 6. Click OK. 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.
