Ltspice iv download old version

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:

http://www.cadence.com/products/orcad/pages/downloads.aspx

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.

*How can I get a version of PSPICE using Schematics?

• 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)

*Obtain a copy of the freshman computing initiative (FCI) CD, which includes PSPICE on Disk 1. This is the student version 9.1. When you install the student version, be sure to choose SCHEMATICS as your interface, not CAPTURE.
