Fujitsu Simulates Graphene Device Using Open Source Tool

Fujitsu announced the simulation of a 3030 Atom Nano device here on January 14th, 2013. The simulation took 20 hours on their supercomputer to simulate the electrical properties of graphene and an insulating layer, using OpenMX Material Explorer.

Even more interesting is the news that OpenMX is an open source tool available from under the terms of the GPL.

Xyce Parallel Circuit Simulator is open source

Sandia National Laboratories has open sourced their parallel circuit simulator.  Also available is documentation and a full set of regressions.  Check out their site at From their site: Xyce is an open source, SPICE-compatible, high-performance analog circuit simulator, capable of solving extremely large circuit problems by supporting large-scale parallel computing platforms. It also supports serial execution on all common desktop platforms, and small-scale parallel runs on Unix-like systems. In addition to analog electronic simulation, Xyce has also been used to investigate more general network systems, such as neural networks and power grids. Xyce developer Eric Keiter has an announcement here on SemiWiki.
