Short Tutorial on PSpice
In this session you will learn how to create a PSpice project to simulate the electronic circuit.
1. Create a PSpice Project
Start up OrCAD Capture CIS
- To use PSpice, start with OrCAD Capture CIS program. When you start up you will get a screen which looks like:
Create a new Project for PSpice
Next, you will use Capture to create PSpice project and simulate the circuit on your computer.
Before you create a new project, it is recommended that you create a directory to store all your projects and files. For example, you can have a directory "PSpice" on the windows desktop ready before hand.
Let's create your first PSpice project now.
- In the main Capture menu, select "File ➤ New ➤ Project...". The following window will appear. Be sure that the Analog or Mixed A/D button is selected. (See figure below) Change it if necessary. This is VERY important.
You will need to fill in the top line Name with a filename (use MyFirstPSpice) and then the bottom line Location with the path name. This is the directory where you will be storing your "project". Click OK to continue the set up.
- Now, the "Create PSpice Project" dialog will appear. Since you are starting a new project, you can change setting to "Create a blank project" and then click OK.
The default setting is that "Create based upon an existing project: AnalogGNDSymbol.opi". You can use the default setting.
- Next, select "PSpice A/D" on the Cadence Product Choices window, then click OK.
- Now, you should come up a blank schematic entry screen.
2. Draw the Electronic Circuit
You can now start adding components and symbols to the schematic by using Place ➤ PSpice Component... menu sequence.
If all of the Libraries shown do not appear on your screen, click Add Library. There you will find a list of available libraries. For this example, you will need the analog.old, the eval.old, and the source.old libraries.
Rotate the Component
You may need to rotate the component on the schematic.
- You can rotate an object by clicking on it to highlight it, then right click the mouse to open the sub-menu. Select "Rotate" function to rotate the component.
- Or, highlight the component, the press "R" key to rotate the component.
Continue placing the components you need. You can change the value of a component by double-click on the component value, and entering a new value. You can connect the components together by placing wires (Place ➤ Wire). When you done you will have something which look like this:
