What is OpenAccess?
OpenAccess is a community effort to provide true interoperability versus
data exchange among IC design tools through an open standard data access
interface (API) and Reference Implementation supporting that. Return to Questions
What is being standardized?
The API and its data model represent the standard.
The Reference Implementation is provided as
a service to provide a production grade solution
"out-of-the-box" for those who wish to take advantage of it and
as the "golden" model of compliant behavior. Return to Questions
Can there be other OpenAccess API implementations?
YES. Anyone can implement a database and put the OpenAccess API on
it. Restrictions are specified in the OpenAccess licenses.
In particular, the Reference Implementation source code is
copyrighted property that may be used by the licensee -- however, this
does not give one rights to copy that code into another OA
implementation. Return to Questions
What is the history of OpenAccess?
The OpenAccess coalition was formed in Q4 1999. 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. As a result, the Cadence Genesis database and API
was selected and now forms the technology base for OpenAccess. Return to Questions
