Analyzing waveform families
Continuing from the example above, there are 21 analysis
runs, each with a different value of R1. After PSpice
completes the simulation, the Available Sections dialog
box appears, listing all 21 runs and the Rval parameter
value for each. You can select one or more runs to display.
To display all 21 traces
1 In the Available Sections dialog box, click OK.
All 21 traces (the entire family of curves) for VDB(Out)
appear in the Probe window as shown in Figure 24.
