A Simple Demo

This step-by-step demo shows how to do the following:




Setting up simulation profile
Edit simulation profile
Place net alias; create netlist and view netlist
Show and hide current and voltage displays

Example 2.1


Draw circuits in Capture
Set up simulation profile from the menu: “PSpice – New Simulation
Profile”




Analysis Type is “Bias Point”
Once the simulation profile is created, you may edit it from the menu
“PSpice – Edit Simulation Profile”
Run simulation from the menu: “PSpice - Run”
Show and hide node voltages and currents values from menu:
“PSpice – Bias Point - Enable”
In PSpice, you don’t need
to include 0 V voltage
source to measure current


Analysis type is “DC Sweep” and the primary sweep variable is Vs (as shown in the figure).
Add current and voltage markers from menu: “PSpice - Markers”
Run simulation from the menu: “PSpice - Run”
PSpice AD will automatically run and show result graph
In PSpice AD, add or remove traces
from menu: “Trace”
Copy graph to MS Word from menu:
“Window – Copy to Clipboard”, then paste

Assignment 2

Reproduce the results of Examples 2.1, 2.2 and 2.3 (pages
26-32). In your report, you will need to include the following
for each of the examples:


Final circuit drawing
Simulation results





Circuit drawing in Capture with current and voltage displays
Simulation results shown in PSpice AD as curves for Example 2.2
and 2.3 (similar to the ones shown on pages 4 and 5 of this handout)
Simulation results as data values for Examples 2.2 and 2.3 as shown
on page 5 of this handout
Prepare your report in Word (or similar word processing software)
following the format talked about in Class 1.
Turn in the print-out of the report next week !
