NASA To Host Open Source Summit

NASA will host a summit about open source software development on March 29-30 at the agency's Ames Research Center in Moffett Field, Calif. The event runs from 9 a.m. to 5 p.m. PDT on both days.

NASA's first Open Source Summit will bring together engineers, policy makers and members of the open source community. Participants will discuss the challenges within the existing open source policy framework and propose modifications to facilitate NASA's development, release and use of software. [more]

SPICE: a 40-year old open-source success story

From EDN:

SPICE: a 40-year old open-source success story
SPICE, the Simulation Program with Integrated Circuits Emphasis, has turned 40 years old. The IEEE has marked the occasion by designating the development of SPICE as a Milestone in Electrical Engineering and Computing. On February 23rd, the Computer History Museum hosted a celebration with a roundtable discussion by the individuals most responsible for bringing SPICE from its origin as a UC Berkeley student project to the huge commercial success it has achieved as the most widely used tool in the semiconductor industry.

The panel (from left to right) consisted of:

• Ron Rohrer - 2002 Kaufman Award recipient, who taught the class at UCB that developed the progenitor of SPICE, CANCER (Computer Analysis of Nonlinear Circuits, Excluding Radiation)
• Larry Nagel - as a student in Ron’s class, Larry took on CANCER as his Master’s degree project, and eventually developed the 1st successful implementation - SPICE2 - as his doctoral thesis.
• Kim Hailey - co-founder (with Shawn Hailey) of Meta-Software, where HSPICE was created.
• Ken Kundert - who led the development of Cadence’s Spectre simulator.
• David Hodges - Distinguished Professor Emeritus at UCB, the panel moderator, who is well known for leading the development of analog IC design in CMOS and for the original (Level-1) Shichman-Hodges MOS device model.

Analog/Mixed-Signal Behavioral Modeling – When to Use What

By Richard Goering on February 20, 2011

So when to use what? The conservative style provided by Verilog-A and Verilog-AMS is useful when there are significant accuracy requirements. This approach can potentially provide a 50-100X speedup over SPICE, but it all depends on how good your modeling is. "If you're a poor modeler, there's a chance you could end up with a model that's as slow as SPICE simulation or even slower," Walter warned.
Real  number modeling, also available through Verilog-AMS with the wreal data type, brings real number values into event-driven digital simulation. It thus has the speed benefits of digital simulation and can leverage the metric-driven verification methodology that's increasingly used by digital engineers. It's good when there are hard performance requirements and limited accuracy requirements. For example, wreal is very useful for full-chip mixed-signal simulations.
The following chart shows the accuracy/speed tradeoff ranges provided by various analog/mixed-signal modeling alternatives. Note that the conservative modeling style has a broad possible range, depending on how good the modeling is.
Also important is the modeling effort. Here we can see that conservative models require the most amount of effort. "You can potentially spend days, weeks, months to develop good behavioral models," Walter said. Wreal models are relatively fast to develop because they're less detailed. An important rule of thumb: "Model what you need, not what you can."
