is a community effort to provide true interoperability, not just data
exchange, among IC design tools through an open standard data
API and reference database supporting that API for IC design. The
OpenAccess Coalition is a neutral organization of industry leaders
that are leading this effort operating under Si2 bylaws.
OpenAccess API is a C++ program interface to IC design data. The
API and reference implementation provide a high
performance, high capacity electronic design database with architecture
designed for easy integration and fast application development. Access
to the reference database source code is provided to allow
companies to offer contributions to future database enhancements and
add proprietary extensions. It will also allow for this database to be
used in production environments where software maintenance is critical.
design environments are a complicated mix of design tools containing
proprietary applications and associated databases, and with
incompatible file formats and syntaxes. IC CAD engineers spend an
inordinate amount of time integrating them with thousands of lines of
translator code. The resulting flows are fragile and error-prone. As
well, they are inefficient and result in longer IC design cycle times.
for industry-wide interoperability, the OpenAccess database allows
users to construct flows incorporating design tools from multiple
sources to best suit their needs.
information about accessing the OpenAccess API specification and
database code is available at OpenEDA.Si2.org.
