The Cadence OrCAD /Allegro FREE Physical Viewer is a free download that allows you to view and plot databases from OrCAD PCB Editor, Allegro PCB Editor, Allegro Package Designer, and Allegro PCB SI technology. If you are using new features from the OrCAD / Allegro platform 17.2 release, you will need to download the latest OrCAD / Allegro FREE Physical Viewer 17.2
General development and support for the OrCAD PSpice Schematics product has been discontinued. We will, however, continue distribution of PSpice Schematics as a download as an aid to our customers who wish to continue using it. (NOTE: Schematics can only be run on 32-bit Operating Systems; Windows 7 and earlier).
Note: All OrCAD downloads require a valid email address. The product downloads are available free to all OrCAD customers. In some cases you will be asked to complete a brief form. The links below will redirect to the OrCAD downloads on cadence.com.

To decompress the file, you need some simple steps. First download the Winrar program if it is not already on your device, and then you can follow the steps through this article dedicated to the decompression method: How to decompress RAR files
In some instances, you may receive an error message stating that the file is corrupt. If you have tried all of the above, and it still doesn't work, download or request a new copy to see if that works.
I am currently writing a bullet point history of the popularization of SPICE in the engineering community. The emphasis is on the path SPICE has taken to arrive on the most engineering desktops. Because of this emphasis, my history begins with the original Berkeley SPICE variants, continues onto PSpice (its limited, but free student version made SPICE ubiquitous) and culminates with LTspice (because, at over three million downloads, it has reached many more users than all other SPICE variants combined).
Design your analog circuit, get a quick preview with fully annotated schematic and BOM, and then run the electrical simulation through eDSim for fast and accurate simulations and reliable design validation. You can also create your schematic from scratch using ST models, or simulate your SMPS and analog ICs from a list of predefined ST application and evaluation board schematics.
ContentsThe download area provides the contents of the CDROM delivered with the book.It contains:the circuit simulation software MicroSim PSpice Evaluation 8 with examples;examples for the digital circuits design suite Lattice ispLever.
Multisim also provides Multisim Live, which is a web-based electronic schematic capture and simulation tool with built-in SPICE, a based analog simulation that allows users to capture and simulate designs using 200 different components, anywhere with an Internet connection. Multisim is currently working on Windows but Linux or MAC users can use Multisim Live. You can download a trail version or student edition with some limitations.
Today, Cadence and TI announced that TI's customers can download PSpice for TI from the TI website. This is, no surprise, a special version of PSpice that works with the analog and mixed-signal models for TI parts. It also works with discrete components like resistors, and with generic models for common analog components such as op-amps. PSpice for TI also comes with OrCAD Capture to allow the design schematic to be entered and edited. Anyone can go to the TI website ti.com and download a copy of PSpice for TI for at no cost. Technically, it is a one-year license, but after a year, you can download a new license, still at no cost. Engineers who are designing systems in any of the markets I mentioned earlier can simulate complex analog designs using the TI-curated library without any design size limitations.
There is a dedicated website pspice.com for all things PSpice. There are forums there with tens of thousands of users. There is a new forum especially for PSpice-TI for users to exchange experience and get questions answered by their peers. There is also a special PSpice for TI page on the website with overview and training videos, along with a link to download the product.
Several commercial versions of SPICE run on personal computers, mostnotably PSpice from Orcad, 888-671-9500.The downloadable Pspiceevaluation package has limited capabilities by standards of solid-statecircuit design, but it can be amazingly useful in simulating vacuum tubeamplifiers, which tend to have fewer components. All examples in this articlecan be run on the MicroSim Pspice evaluation package. Other well-knownSPICE implementations include ElectronicsWorkbench, 800-263-5552, and ICAP/4, from Intusoft,P.O Box 710 San Pedro, CA 90733-0710; 310-833-0710. Duncan Munro's listof SPICE vendors may contain some hidden treasures. WinSpiceis a free Spice3F4 Port for Windows 95, 98, 2000 & NT. Veryintriguing. It will simulate much larger circuits than evaluation PSpice.
