Minutes

Attendance/Quorum

We have 3/5 eligible entities, and have a working quorum.

Patent Policy

The Patent slides were offered for review.

No new claims were disclosed at the call for essential patent claims.

Agenda Approval

Motion by Dave G, seconded by John. Motion is approved.

Previous Minutes

Ray moved and John. seconded the approval of the October 4, 2010 minutes. The motion was approved.

Action Item Review

Steven reviewed the open action items.

Liaison Reports

P1800 is considering an errata update to their standard, consisting of editorial issues.

Joe will be reviewing his notes for presentation to IEEE SA.

Inter-operability

John asked for feedback on the Version 1 clarifications, to resolve whether there are stiil pending issues. Dave asked about the TBD item and John noted that he was waiting for feedback from Steven to close out that item.

Steven introduced the prototype registry. Dave asked about the scope of the key_keyname listed in the Public Key section. John also noted that tool version information was also a necessary information item. John asked about the Public Endorsements section, and Steven described it as a place for parties to acknowledge that they have completed interoperability validation against that tool.

John talked about the key scope discussions at Mentor, and suggested that there might be some guidelines we could recommend via P1735.

1. Tools that don't share the same codebase should not share a key
2. Convenience argues for common keys, but IP authors will want finer-grain controls if possible.
3. Validity periods are arguably a private matter for the key owner, but longer periods have a lot to recommend.
4. IP author validation against a particular key violates expectation when the key is reused for a new tool the author never validated.

Duth asked about more public availability of keys. Steven and John noted that the commercial support teams were the most appropriate way for IP authors to gain access to those keys, and that better conventions for key exchange were part of ongoing P1735 discussions. The Interoperability Registry is intended for working group use, rather than public public_key distribution.

License Management

Key Management

John discussed his comments to the proposed Key Management recommendations. One of the potential actions going forward would be setting up an EDA certificate authority. The working group consensus argues against bumping the version pragma for the key management recommendations, and instead reserve those increments for issues that affect backward compatibility.

Standard key vaults improve usability and convenience, but don't improve trust without a CA.

Rights Management

Dave G noted Parminder's participation, and Synopsys expectation to discuss rights in the next meeting. Steven recommended coloring conventions for new material, and John suggested inline comments and TWiki signatures as additional contribution tracking tools.

Work Plan

Duth asked about the current working group schedule and Steven pointed to the P1735WorkPlan page.
