Learn to design a circuit with PSpice is a task quite simple and is enough a few pages of any manual available on line to do it. What can be confusing is the number of files with different extensions that belong to this great tool of electronic simulation. This is due to the history of PSpice, which initially developed to be used in PC by Microsim passed after to OrCAD which was at last acquired by Cadence. The original CAD Microsim was Schematics. After, the program was provided with a design tool more advanced, Capture, maintaining the ability to still use Schematics.

Only the libraries lying inside the following folder can be used for Pspice simulation - tools capture library pspice To make parts from discrete.olb simulate in Pspice, do following - 1) Add property PSPICETEMPLATE with the value (see the part from eval.olb to know about value). It basically tells the port order (by providing the pin. When the part symbol is correct, save the library. The program also prompts to save the part. 5 Simulating With the Part Symbol Schematics are drawn, and PSpice simulations are run from within the capture program, the same program used to edit the library symbol above.

  • The “Capture and PSPice only” option is all that you would typically need for circuit simulation. The full version is installed in the Broun Hall computer labs. The supported schematic entry tool is Capture. This replaces the older schematic entry tool called Schematics.
  • I, personally, found PSpice more user friendly. It took me more time to get the interpretable results from LTSpice than from PSpice. PSpice is friendlier to larger schematics. PSpice has more libraries, although there are not a lot of libraries for Linear Technology parts. I wish there were a way to import the models from LTSpice to.
  • Once the model library and symbol library are saved to disk, open the PSpice Schematic Editor. Select Analysis, and then select Library and Include Files. Select Browse to look for the Model Library that contains the model that is to be used in the schematic; open the Model Library; select Add Library and then OK.

Fortunately, the syntax used to describe a component remained the same, and all libraries with mathematical models, are the . LIB. Creating the design of a circuit with PSpice Schematics, the project will be composed of a schematic file .SCH, a control file .CIR and a circuit description file .NET both automatically generated from Schematics, and files .INC containing subcircuits, to be included in the project. The libraries containing the mathematical models to be added to the project are always .LIB, while libraries that contain graphic symbols associated with the mathematical models are the .SLB.

By using the tool of OrCAD Capture, the main project file becomes the .OPJ, and symbolic libraries are now .OLB. In short, in Schematics a component is completely defined by libraries .LIB and .SLB while in OrCAD Capture by the couple .LIB an .OLB.

Currently most of designers use OrCAD Capture for the circuits design, however, the same Capture has a tool to convert project designed with Schematics and convert .SCH and .SLB in .OPJ and .OLB. We ‘ll see how in a dedicated article.

PSPICE Links (Updated Sept. 14, 2010)

*The current supported version of PSPICE is sold by Cadence under their OrCAD product line. You can download a demo CD from their website here:

The “Capture and PSPice only” option is all that you would typically need for circuit simulation.

. The full version is installed in the Broun Hall computer labs. The supported schematic entry tool is Capture. This replaces the older schematic entry tool called Schematics. For those who would still like to use Schematics, see the information below. Another excellent simulator using the SPICE engine is LTSpice, which is freely available from Linear Technologies here:

At this writing the current version is LTSpice IV.

  • Legacy versions of PSPICE using Schematics for schematic capture are available as described below. They are reportedly unstable under Windows later than XP (e.g., Vista, 7).The two versions are: 9.1 (free student version) and 9.2 (“professional” version – no longer supported).

* Where can I get my own copy of PSPICE using Schematics? (the student version 9.1 is free).

*Download locally from Dr. Roppel's web site (file name = 91pspstu.exe). This is the student version 9.1. When you install the student version, be sure to choose SCHEMATICS as your interface, not CAPTURE. (Note: the file size is about 28 MB)
