OrCAD PSpice Tutorial Opening of OrCAD PSpice 9.1:Steps: 1. Go to start button
All programs
OrCAD Release 9.1
Or Double click on the shortcut of ‘Capture CIS ‘on my desktop.
Capture CIS
2. After clicking on ‘Capture CIS’ a window named ‘OrCAD Capture [Session log]’appears.
3. Go to File
New
Project
4. After clicking on project a window named ‘New Project’ appears.
5. Here give the project name like ‘test’ as well as select ‘Analog or Mixed-Signal Circuit Wizard’ and click on ‘Browse’ button to give the path like ‘C: Documents and Settings\manas’. Then click ‘OK’ on ‘Select Directory’ window and again ‘OK’ on ‘New Project’ window.
6. After clicking ‘OK’ a window named ‘Analog Mixed-Mode Project Wizard’ appeared. It is for adding symbol libraries. After adding libraries click on ‘Finish’ button.
7. After clicking ‘Finish’ a window named ‘OrCAD Capture - [I-SCHEMATIC1:PAGE1)]’ appeared. This is just like breadboard on which components can be placed.
8. As indicated the bar at right side called ‘Tool Palette’ bar from where you can get different component. Now click on the ‘Place part’ button.
9. After clicking ‘Place part’ button a ‘Place part’ window appeared.
10. Click on ‘Add Library’ button. A ‘Browse File’ window appears. Then select all by clicking and draging the left button of the mouse. Then click on ‘Open’ button.
11. For generating a click on ‘Place part’ button. Then go to Analog library and select ‘R’ from the part list then ‘OK’.
12. For placing the resistor on breadboard just left click the mouse once on it and for deselecting press the ‘Escape’ button from keyboard.
13. For generating diode click place part. Then go to ‘Diode’ library and select ‘D1N4148’ from part list then ‘OK’. For placing it follow the procedure stated in step 12.
14. For generating a sinusoidal source click place part. Then go to ‘Source’ library and select ‘VSIN’ from part list then ‘OK’. For placing it follow the procedure stated in step 12.
15. For generating a ground click on the ‘Place Ground’ button from ‘Tool palette’ bar.
16. Then go to ‘Source’ library and select ‘0’ from part list then ‘OK’. For placing it follow the procedure stated in step 12.
17. For generating a wire click on the ‘Place Wire’ button from tool palette bar.
18. Then connect all the component according to desired circuit diagram of a half wave rectifier.
19. For giving the value of the sourse double click on names and giving corresponding values like ‘ VOFF=0 & ‘OK’, VAMP=5v & ‘OK’, FREQ=50 & ‘OK’.
20. Then go to ‘PSpice’ present on tool bar and click on ‘New Simulation’ Profile.
21. Then ‘New Simulation’ window appeared. Write your project name like ‘test’ in the blank space of name. Then click ‘Create’.
22. After clicking ‘Create’ button a window named ‘Simulation Setting-test’ appears. Here set the Runto time to 100ms (i.e. multiple of time period of given source signal{1/50}). Also set the Maximu step size to 0.0001 for getting smooth curve. Then click Apply and OK.
23. For placing the port click on ‘Voltage/ Level Marker’ and place it at input side and output side or at any point on circuit according your requirement.

24. Then go to PSpice and click run.
25. Now simulated curve appears. Then Save your project and Exit.
ALL THE BEST
