Hi All, It seems that at least some of us did not receive this email so I am resending. -Chas -------- Original Message -------- Subject: SV-CC Meeting minutes for 12/20/2006 Date: Wed, 20 Dec 2006 20:51:07 -0500 From: Charlie Dawson <chas@cadence.com> Reply-To: Charlie Dawson <chas@cadence.com> To: SV-CC <sv-cc@eda-stds.org> Minutes of 12/20/2006 SV-CC Meeting. ATTENDEES 000000000 666666666 111110000 221009988 200212131 068517306 xxxxxxxxx Charles Dawson xx-x-xxxx Ralph Duncan xxxxxxxxx Jim Vellenga xxx-x-xxx Andrzej Litwiniuk x-xxxxxxx Abigail Moorhouse -xxxxxx-x Michael Rohleder xxxxxxxxx Chuck Berking xxx-xxxxx Bassam Tabbara x-xxxxxxx Francoise Martinolle ----xx-xx Amit Kohli xxxxxxxx- Ghassan Khoory 1. Reviewed Patent information. - Chas reviewed the patent information. 2. Reviewed minutes of the 12/06/2006 Meeting. Abi did not receive the minutes or the agenda. More problems with the reflector? Chas will look at the bounced messages. Chas commented that Ralph's description on the rand stuff was better than our meeting minutes (email sent on 12/13). Discussed whether or not to include them. Decided to just refer to them here. - Chuck/Ralph. ACCEPTED (unanimous) 3. Liaisons - Chas asked if anyone had an objection to moving to the alternate Wednesdays so as to not conflict with SV-XC. No one objected. Chas will do so if the SV-XC cannot move their meeting. - Francoise talked about having a face-to-face at DVCon. 21-23rd of Feb. - Francoise reported that the SV-EC is discussing an Updated Event Scheduling Proposal. 4. New business - DPI and "rand" qualifiers Ralph is going to slog through the grammar. Ralph sees no problem to providing the relief that was requested. Should not cause problems nor be noticeable by the end user anyway. Goal is to provide a general principle that will help deal with things that we haven't already thought of yet. Andrzej thinks that we need to either specify the C declaration or assume that things that are not specified cannot exist on the C side. Any kind of control bits do not get passed going from C to HDL. - SV-EC's Updated Event Scheduling Proposal SV-EC is going to be adding some new regions for program blocks. This will allow people to use non-blocking assignments in the program blocks. Since VPI has callbacks around the non-blocking assignments in the active loop, we would need to add similar callbacks to the reactive loop. It should be noted that this going to cause backward compatibility issues. Chas forwarded Francoise's message about the proposal. Should not cause changes of the data model, but will cause changes to callbacks and to put values with delays. 5. Reviewed items with proposals. - Item 1684 vpiParent clarification needed for complex var/net objects Does this explain clearly how to deal with a slice as an argument to a systf? It would be good to clearly state that. Maybe we can create a general statement to that effect. Maybe we need to pass the packed array item first so we can refer to it in this one. Jim pointed out that we have a left-to-right or right-to-left problem which needs to be fixed. Decided to postpone decision on this until after the resolution of the packed array proposal that Chuck is working on. JimV/Chuck. Meeting ended at 1:02pm. 6. Reviewed SV-CC items with proposals (Straw poll only). 7. Old Business 8. Action items - Ongoing review of Michael and Abi's compatibility proposal. - Francoise and Bassam to continue work on assignment patterns. - Francoise to champion adding support for typed parameters to the typespec diagrams. - Abi to champion adding support for parameterized classes. - Abi/JimV to champion improving the ability to compare objects. - Steve Dovich to determine best way to deal with issues between versions of the IEEE specs. - Ralph to review the BNF for areas related to "rand". - Chas to reconcile the meeting schedule between SV-CC and SV-XC. 9. Items for consideration at the next meeting (they already have proposals): - Item 1614 P1800-2005: 27.52 no expr for disable fork objects - Item 1631 P1800-2005 27.14 note k has an error - Item 1664 IEEE 1800-2005 27.7 Note 'e': First sentence should be rewritten - Item 1669 P1800-2005 Sections 27.34 and 27.36 commas are inconsistent - Item 1632 P1800-2005 sections 27.14 note k and 27.22 note f are incompatible - Item 1684 vpiParent clarification needed for complex var/net objects 10. Next meeting The next SV-CC meeting will be on 01/03/2007. The next P1800 meeting will be on 01/04/2007. -- Charles Dawson Senior Engineering Manager NC-Verilog Team Cadence Design Systems, Inc. 270 Billerica Road Chelmsford, MA 01824 (978) 262 - 6273 chas@cadence.com -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.Received on Tue Jan 2 13:23:32 2007
