1. 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

2. 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

3. Must I use the Reference Implementation to be compliant to the standard?
NO. The Reference Implementation is being provided as a service that may be used for your solution but need not be. Only the API defines the standard and only the API need be used to be compliant. However, if cases arise where the API is found to be incomplete or ambiguous, the Reference Implementation's will define the standard behavior.

4. 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.

5. What are the advantages of OpenAccess for OEM and IC companies?
  • Enables tools (EDA vendor products, proprietary tools, university research) to be integrated to form a complete solution
  • Enables tool choice to improve design productivity
  • Provides true interoperability and concurrency
  • Eliminates costly/lossy data exchange
Return to Questions

6. Why is "Open" access important?
  • Allows customer choice of best-of-breed tools
  • Allows customer to dictate the design flow Promotes EDA tool competition
  • Provides global enterprise and cooperative design sharing
  • Enhances technology-transfer of university research.

7. 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.
