---+++ 1. Call to order on July 14, 2009 at 8:03 PDT

Ernst welcomed the participants and started presenting the [[%ATTACHURL%/090714_mtg_slides.pdf][meeting slides]].

---+++ 2. Approval of Agenda

Agenda unanimously approved.

---+++ 3. Administrative Issues
   * *Slide #4:* WG Status
      * John mentioned that, even if Accellera is entity-based, the IEEE WG to which an Accellera approved standard is transferred is not forced to be also entity-based, although this is encouraged.
   * *Slide #5:* WG Membership
      * A new fresh WG roster will be build from the first next WG vote.
   * *Slide #6:* Web Site
      * New Twiki web site under construction. Some information moved and updated from previous web site.
      * Alain to tell David when the old URL (!http://www.eda.org/vhdl-ams) can be redirected to the Twiki home and the eda.org page can be updated with the new URL.
   * *Slide #9:* Call for Participation
      * Ernst proposed to also contact former balloters of 1076.1 and 1076.1.1.
      * John proposed to also add the balloters of 1076, even if they may not be primarily concerned with AMS extensions. Approved.
      * Alain proposed to also consider the ECSI organization. Approved.

---+++ 4. Review of IEEE Patent Policy
   * Ernst presented the [[%PUBURL%/P10761/WebHome/pat-slideset.pdf][IEEE Patent Policy slides]].
   * Alain asked if the slides have to be presented at each meeting. Ernst suggested that only the first slide would be needed.
   * John mentioned that it is enough to make a statement at the beginning of each meeting that there is a policy and everybody can find the information on the IEEE SA web site (http://standards.ieee.org/board/pat/pat-slideset.pdf) or on the WG web site.

---+++ 5. Revision Ballot of IEEE Std 1076.1.1
   * Ernst will initiate a working group vote on the draft P1076.1.1 PAR in a few days with a 14 day response time.

---+++ 6. Planning for Next Revision of IEEE Std 1076.1
   * IP protection
      * John mentioned the work of the [[P1735.WebHome][P1735 WG]] whose charter is to develop industry interoperability rules. Pragmatic approach, easy-to-implement rules. Digital rights to be addressed next year.
      * Ernst asked about the implications on HDLs.
      * John replied that this would be in the form of modified or new pragmas.
      * David stressed that P1735 cannot change VHDL or (System)Verilog standards.
      * John replied that this would be only recommendations to other standards. Actually, there is a common set of members in P1735, P1076 and P1364/1800.
      * David raised the issue of P1735 and P1076 being (re)issued at the same time.
      * Ernst concluded that 1076.1 will first include the IP support offered by 1076-2008.
   * VHPI
      * Need to review the status of previous work on VHPI for VHDL-AMS (work from Martin Vlach).
      * David proposed to ask for possible donation from EDA vendors who have done some work in this domain.
   * Generic types and packages
      * More detailed analysis on the implications to 1076.1 is required.
   * PSL
      * David thought this should be a separate issue when upgrading 1076.1 to 1076-2008. Should be considered as an extension to 1076.1.
      * Ken stressed that the effort to support [[VerilogAMS.AmsAssertions][Verilog-AMS assertions]] is not primarily interesting. It is better to consider extending PSL to AMS.
      * David suggested to consider !SystemVerilog assertions.
      * John noticed that the incorporation of 1076-2008 will only concern the digital context and there should be some provision to prevent the analog context to be included in PSL statements.
   * External names should include quantities.
   * The importance mentioned in slides 15 to 20 is Ernst's perspective. This should be anyway determine through a WG poll/vote.
   * Mixed netlists
      * Ken mentioned that each EDA vendor has proprietary means to support automatic insertion of interface (conversion) elements.
   * Parameter sweep
      * David stressed that this is more a tool (control language) issue: amount of re-elaboration, incremental elaboration.
   * Table-driven modeling
      * Joachim made a proposal, but no progress on that for the moment.
   * Pass function name as parameter
      * John mentioned that 1076-2008 only considers static passing at elaboration time.
      * Ernst confirmed that the requirement is to have static definition only.
   * Unified use of SPICE models
      * Joachim reported on VDA efforts. Only a subset of SPICE primitives has been developed (see the [[http://fat-ak30.eas.iis.fraunhofer.de/vdalibs/doc/frames.html][SPICE2VHD library]]) following the guidelines described in this [[%PUBURL%/P10761/WorkingGroupDocuments/Spice_in_vhdl-ams_0.6.pdf][proposal document]] and the same effort done for Verilog-AMS. See also the full [[http://fat-ak30.eas.iis.fraunhofer.de/mb/index_en.html][VDA library]] available at http://fat-ak30.eas.iis.fraunhofer.de/mb/index_en.html.
         * There is still the need to understand the scope and the objectives before considering the integration in 1076.1.
   * Unified C interface
      * David suggested to consider the Direct C interface in !SystemVerilog.
   * Support of HIL simulators
      * Early requirements have been defined by Eduard Moser ( [[http://%HTTP_HOST%/vhdl-ams-old/ftp_files/wp/rt_subset_draft.txt][text document]] of Dec. 2, 1999).
   * Standard symbol format
      * David reported on the [[http://fat-ak30.eas.iis.fraunhofer.de/exchange/index_en.html][SVG-based symbol exchange format]]. Currently defines a mapping from 1076.1 language elements to SVG. Difficult to include graphical information (attributes) in 1076.1.
   * Frequency-domain modeling
      * Joachim's [[%PUBURL%/P10761/WorkingGroupDocuments/Haase_FDL09.pdf][proposal]] to be presented at FDL'09.
   * Planning of 1076.1 revision
      * David stressed the need to define a prioritization of importance.
      * John proposed to include the revision process in the PAR, e.g., what is in scope and what is out of scope.
      * Ernst thought that we need some perspective on that before we can include it in the PAR.
      * John thought that having champions does matter, but the working group community must agree on the importance, the scope and the objectives.
      * David suggested that we may need feedback from outside the working group, e.g., VDA, etc.
      * John suggested also briefing the DASC.
      * Ernst replied that he is regularly attending DASC meetings, giving updates on the WG activities.

---+++ 7. Next Meeting
   * Ernst proposed to have a telco each first Tuesday of the month at 3pm GMT. Approved.
   * Alain to organize a face-to-face meeting at FDL'09 (Sept. 22-24). Telco will be required. Internet access also, if possible.

---+++ 8. AOB

None.

---+++ 9. Adjourn

Ernst adjourned the meeting at 9:15 PDT.
