Si2 Announces Release of OpenAccess Scripting Interface

oaScript Enables Powerful, Engineer-Friendly Interface to OpenAccess API

AUSTIN, Texas — (BUSINESS WIRE) — November 26, 2013 — Si2 today announced the latest release of its oaScript Extension Language Bindings package, version 2.3, enabling design engineers direct access to the OpenAccess API through popular open scripting languages including Python, Tcl, and Ruby. Development of oaScript was made possible by contributions from members of the OpenAccess Coalition, including Altera, AMD, Intel, Oracle, Synopsys, and others.

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++.

“Synopsys has contributed extensive engineering resources to the new release of oaScript,” says Paul Lo, senior vice president and general manager, Analog/Mixed Signal Group at Synopsys. “Design engineers and developers can now write their own scripts to quickly, easily and directly obtain and manipulate OpenAccess data while preserving OpenAccess interoperability.”

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. The packages are available at this link:
