To set up and run a parametric analysis to step the value of R1
using Rval
1 From Capture’s PSpice menu, choose
New Simulation Profile.
The New Simulation dialog box appears.
2 In the Name text box, type
Parametric.
3 From the Inherit From list, select AC Sweep, then click
Create.
The Simulation Settings dialog box appears.
4 Click the Analysis tab.
5 Under Options, select Parametric Sweep and enter the
settings as shown below.

6 Click OK.
7 From the PSpice menu, choose Run to start the
analysis.

page associated with the simulation profile
you are creating.
This profile specifies that the parameter
Rval is to be stepped from 100 to 10k
logarithmically with a resolution of 10
points per decade.
The analysis is run for each value of Rval.
Because the value of R1 is defined as
{Rval}, the analysis is run for each value of
R1 as it logarithmically increases from
100
Ω to 10 kΩ in 20 steps, resulting in a
total of 21 runs.
