Monte Carlo analysis

To set up the analysis
1 From PSpice’s Trace menu, choose Performance
Analysis.
2 In the Save data from list box, choose All.
3 Click OK.
Creating histograms
Because the data file can become quite large when
running a Monte Carlo analysis, to view just the output of
the filter, you place a voltage probe at the output of the
filter.
To collect data for the marked node only
1 From the PSpice menu, choose New Simulation
Profile or Edit Simulation Settings from the PSpice
menu. (If this is a new simulation, enter the name of
the profile and click OK.)
The Simulation Settings dialog box appears.
2 On the Data Collection tab, choose the At Probes only
option.
3 Click OK.
To run the simulation and load Probe with data
1 From Capture’s PSpice menu, choose Run to start the
simulation.
When the simulation is complete, PSpice
automatically displays the selected waveform.
Because PSpice ran a Monte Carlo analysis, it saved
multiple runs or sections of data. These are listed in
the Available Sections dialog box.
2 From PSpice’s Trace menu, choose Performance
Analysis.
3 Click the Select sections button.
4 In the Available Sections dialog box, click All.
