The AC analysis sweeps 50 points per decade from 100 Hz to 1 MHz. The Monte Carlo analysis is set to take 100 runs. Save data from all runs and set the output variable to V(OUT). 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 Profile. (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 Markers Only option for each type of marker (Voltages, Currents, Power, Digital, Noise). 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. In the Available Sections dialog box, click All. 3. Click OK.
