[2] The OpenAccess Coalition is an organization of semiconductor industry companies claiming to be competition-neutral that are leading this effort operating under Silicon Integration Initiative bylaws.
It also includes the reference database supporting that API for IC design in multiple programming languages: C++, C#, Perl, Python, Ruby and Tcl.
In the past, electronic design flows were a combinations of proprietary applications and copyrighted EDA databases, with many different file formats and syntaxes.
The members issued a request-for-technology for existing technology, looking for a solution that was proven and would be commercially adopted, and that supported a broad set of EDA tools.
In 2005 the Cadence Berkeley Labs and the Silicon Integration Initiative launched the OpenAccesGear, a project to develop open source utilities on top of the OpenAccess database.
