SaberRD Student Edition — One Year Later
One year has passed since the first release of the SaberRD Student Edition in September 2010. In that time, it has been retrieved by thousands of individuals around the globe who are using it to support academic coursework and research, to evaluate the Saber technology, or simply to satisfy a personal curiosity to learn more about Physical Modeling and Simulation for multi-domain systems. The release of the SaberRD Student Edition represents an important (and long overdue) milestone in the history of the Saber products. For the first time since becoming commercially available over 25 years ago, the Saber technology is readily-accessible to students, professors, researchers, and individuals who require capable tools for modeling, simulating, and analyzing dynamic system behaviors.

What others are saying...

"SaberRD is an excellent CAD platform! I am especially impressed by the well-organized technical documentation and ribbon tool bar. Thank you so much for providing the student version of SaberRD, which I have found to be better than any of the SPICE simulators I have used. SaberRD will be my priority tool for design and verification of my DC-DC converter project." — Yu Long, Graduate Student at University of Tennessee

The latest release of the SaberRD Student Edition (version 2011.09) features significant improvements to performance, stability and usability. It's faster... expect a 2x to 4x speed-up in simulation runtime. It's more robust…more designs run right out of the box. And it can model more systems…new MAST parts and VHDL-AMS libraries have been added. We encourage you to take a look, whether you are upgrading from a previous version or if this is your first experience with SaberRD. And as always, we greatly value your feedback and appreciate the time you've taken to provide your inputs.

Proven Saber Technology

An ecosystem is rapidly forming in support of Physical Modeling and Simulation activities around the world: the cumulative effect of the tools, techniques, models, expertise, collaboration and research supporting initiatives to 'electrify' traditionally non-electrical systems. In providing the SaberRD Student Edition, it is our goal to support the development of expertise and capability within this ecosystem. Ultimately however, your involvement will determine the impact of this community. We invite your participation in the wide array of online resources that support the Physical Modeling and Simulation community, including the Saber User Forums... ask questions... share your experiences... suggest ways to improve. Inspire the ecosystem!

SaberRD in the Classroom — University of Southampton
Professor Peter Wilson of the University of Southampton shares his classroom modeling and simulation experience with SaberRD along with two exciting "real world" class projects in his article, SaberRD Simulation in the Classroom and Beyond. Professor Wilson highlights how SaberRD helps him to teach analog electronics — often considered a "dark art" and a "tough" course — in a way that is more accessible and less intimidating to students. His class then put to work the results of their modeling and simulation by building a fully operational solar electric racing boat — a winning craft named "Tarka II" — and an electric car. The article provides fascinating details and photos of these projects along with impressive competition results. Way to go Team Southampton!
