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 Jarek, seconded by Dave G. Motion is approved.

Previous Minutes

Ray moved and Dave G seconded the approval of the February 6, 2011 minutes. The motion was approved.

Action Item Review

Steven reviewed the open action items.

Liaison Reports

Steven is working w/ IEEE SA Professional Services on Technical Editor contracts.


Jarek noted that he had posted a set of issues to the reflector and is currently reviewing a few areas of concern. Feedback from working group members will help finish up the review. John noted that his internal interoperability work was aligning with Jarek's recommendations and had not be noticed during development. Jarek flagged compatibility for IP owners implementing encryption scripts as a primary concern.

John noted that P1076 would be the likeliest place for issues, and Jarek indicated that he was already working with the P1076 chair to smooth acceptance. John pointed out that our status as a recommendation document could resolve this without imposing further constraints in the VHDL LRM.

Jarek suggested that the Rights encryption process be documented from the standpoint of someone unfamiliar with current pragma processing and encryption tools.

License Management

Dave G reported that Synopsys had internal discussions in progress to bring a recommendation forward to the working group. He expects a proposal to the reflector shortly.

Key Management

Rights Management

Dave G requested that we schedule an approval vote for the Rights Management recommendations. Steven agreed to call for that vote in the next meeting.

Other Business

Dave G sent out a statement on Key Scope, and is working on additional rationale before preparing a proposed recommendation.

Dave G described a possible issue with the handling of compiler directives when encrypting. The examples are handling of macros and include directives in the protected region. John noted that lots of these issues can all have several mutually incompatible but desirable outcomes. Steven noted that feature control and/or diagnostics could be specified for either the encryption or decryption phases of the protected IP flow. John asked for feedback from the IP producer community to help shape the consensus in this area.

Next Meeting

The next P1735 meeting is scheduled for March 19, 2012 at 16:00UTC.
