Si2 Announces Release of OpenAccess Scripting Interface v3.0

Si2 today announced the release of the OpenAccess extension oaScript v3.0. This latest version of oaScript, from the Extension Steering Group's oaScript working group, contains several new features enabling an even larger community access to this standard. oaScript v3.0 now has support for Python on the Windows operating system and support for Python3 and Ruby 2.0. In addition, there is new support for Python exceptions inside the OpenAccess observer routines, giving the OA community greater control of their scripted applications.

Conventional access to the design data contained in an OpenAccess database has historically required C++ programming through an EDA vendor’s software tool or direct access to the OpenAccess C++ API. While some vendor tools include integrated scripting features, their implementations are usually proprietary and lack cross-vendor interoperability. The oaScript Extension Language Bindings are built directly from the OpenAccess C++ API, thus allowing maximum flexibility, regardless of which vendor tool created the design. Scripting languages are often preferred by engineers to perform various design tasks without resorting to compiled software design languages such as C++.

“Development of oaScript was made possible by contributions from members of the OpenAccess Coalition, including Altera, AMD, Intel, Oracle, Synopsys, and others,” says Rudy Albachten, PMTS CAD Engineer at Altera, and Chair of the OpenAccess Coalition. “Extensive support also came from Si2’s Silicon Photonics TAB, which is developing OpenAccess extensions specifically for the development of photonic integrated circuits. This is an excellent example of how Si2’s different projects can cross-pollinate to achieve a more robust and cost-effective solution to industry needs.”

Suggested uses include accessing hierarchical design data, connectivity information, and layer and constraint details. In addition, PDK developers can now develop their process design kits with a scripting language, as well as creating script-based test cases to better automate their quality assurance techniques.

The oaScript Extension Language Bindings package has been contributed by the Extension Steering Group (ESG), operating under the OpenAccess Coalition. All Si2 members can have access to the binary releases for each of the active OpenAccess streams by signing the ESG License. In addition, OpenAccess Coalition members have access to the source code along with redistribution rights. Currently, Python 2.5-3.3, Ruby 1.8-2.1, and Tcl 8.4-8.6 are supported. Any OAC member company wanting additional scripting languages support should get in touch with Si2. The packages are available at this link: https://www.si2.org/openeda.si2.org/projects/oascript/.

A presentation on the new features of oaScript v3.0 will be held on Wednesday, June 4 at 4:00 p.m. in Si2’s Booth #1107 at the Design Automation Conference, see abstract here: http://www.si2.org/dac_2014/abstracts/kevin_si2_abstract.php.

Data is the fuel that drives the machine learning algorithmic engines and ultimately provides the business value. In his session at Cloud Expo, Ed Featherston, a director and senior enterprise architect at Collaborative Consulting, discussed the key considerations around quality, volume, timeliness, and pedigree that must be dealt with in order to properly fuel that engine.
WebRTC defines no default signaling protocol, causing fragmentation between WebRTC silos. SIP and XMPP provide possibilities, but come with considerable complexity and are not designed for use in a web environment. In his session at @ThingsExpo, Matthew Hodgson, technical co-founder of the Matrix.org, discussed how Matrix is a new non-profit Open Source Project that defines both a new HTTP-based standard for VoIP & IM signaling and provides reference implementations.
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound e...
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
