1. Reviewed Patent information.
- Charles Dawson read the patent information.
2. Reviewed minutes of the 12/01/04 Meeting.
- Doug/Joao. Accepted.
3. Liaisons
- Chas/Francoise to report on Champions meeting.
Zero replication. We need to take a look at that one.
BTF item 547. Uwire and types on nets.
Joao and Doug were there too.
- SV-EC meeting. They decided that strings should not
have NULL characters.
- No other meetings were reported on.
4. New business
- 201 More details needed on DPI string argument handling
Motion to reconsider approval of 201: Steve/Joao. ACCEPTED
Motion to amend proposal for 201: Doug/JimV. ACCEPTED
Motion to accept proposal: Doug/JimV. PASSED
- 050 Change DPI svLogicVec32 representation to match PLI/VPI aval/bval representation
Motion to reconsider: Doug/Joao. ACCEPTED
Most agreed in principle to the proposal made by Oz. Doug would like to go a step
further and eliminate some of the DPI routines. Andrzej was concerned about
the standard restricting implementors in the way that the data is stored.
Motion to table: Steve/JimV. ACCEPTED
Joao took an action to setup a separate meeting to discuss.
- 064 Note 20 of section 31.10 is unclear
Motion to re-consider: Francoise/Dovich ACCEPTED
Motion to table: Francoise/JimG. ACCEPTED
Francoise and JimG will write a new proposal.
There was discussion about the lack of clarity in the specification on the
return values for many of the properties. It would be good to have a table
for each property like vpiScalar and vpiVector and their return values.
JimV to enter a new SV-CC item for future consideration.
- 333 VPI support for types on wires
Michael is concerned about how extensive of this proposal was at this late
date. Francoise was unclear on access to cont assigns from nets.
Francoise to discuss further with JimV. It was clear that more time was
needed to review the proposal. ALL to review for next week.
- 053 VPI access to instances and packages is incorrect
Chas reported that he has a proposal almost ready to go. Should be out
shortly.
Meeting ended at 1:05pm (EST)
- 054 What is the vpiFullName of a package?
Chas reported that there is a bugnote that has been added indicating his
idea on how to proceed, and he asked the committee to review and comment
on the idea.
- 055 fullnames of declarations in the global scope of a compilation unit
Chas reported that there is a bugnote that has been added indicating his
idea on how to proceed, and he asked the committee to review and comment
on the idea.
- 056 vpi_handle_by_name on imported items?
Chas reported that there is a bugnote that has been added indicating his
idea on how to proceed, and he asked the committee to review and comment
on the idea.
- 062 Conflicting vpiArray property descriptions in 31.10
- 077 VPI diagram for instances shouldn't refer to reg objects
- 332 VPI support for new uwire net type
JimV reported that there is a simple solution already in the description,
so this one should be easy.
5. Reviewed of items with proposals.
- None.
6. Old Business
Meeting ended at 1:05pm (EST)
7. Action items
SV-CC action items:
- Francoise to ask Peter Ashenden what was done to improve
printing from Rational Rose.
- Francoise to inquire about the feasibility of third parties
shipping the UML for the diagrams.
- Sachi to drive finding a better solution for 052.
- Chas to add Stu to SV-CC email alias.
- JimV to enter a new SV-CC item for adding tables for return values of
the properties.
- Joao to setup a meeting to discuss Item 050.
- ALL to review proposal for Item 333 for next meeting.
PTF action items:
- Steve to compare BNF with the access available
for attributes to see if they match
- Francoise to remove "+" from tags in UML diagrams and
add vpi prefix where appropriate.
- Francoise to send out HTML for 1364-2001 diagrams, using
something other than JPG for importing diagrams into frame.
- Stu to write proposal for PTF 368.
- Francoise to write proposals for PTF 373, 374, and 396.
- Steve to write proposals for PTF 311, and 495.
- Sachi to write proposals for PTF 307, 312, and 313.
- Stu to enter new PTF item for save/restart/reset issue.
- JimG to write proposals for PTF 517, 533, and 534.
- Chas to write proposal for PTF 296.
- Francoise to lookup wording for PTF 524 in VHPI.
- Francoise will open a new PTF issue to look for situations like 25.6.15,
where multiple methods are used access the same object enclosure
- Chas to reword proposal for PTF 525.
- Draft a straw man proposal using a clean slate with no concern for
existing PLI/VPI on the best way to represent all Verilog and
SystemVerilog kinds and types. This straw man will then be used as a
basis for discussing backward compatibility with the existing reg, net,
variables, functions, and parameter diagrams. It may be decided that
full backward compatibility is not possible, or is not the best approach
moving forward.

at ROsync time and putting values in future times.

occur in, when the order is important.
