Objective of this meeting was to go through the "AMS Enhancement" items to 
identify the ones we want to do / close / group into common items etc.

Item 2803: - Has been addressed as part of "Cleanup" items.

Item 840: - dealing with the system function $isPortsShorted. The consensus was 
this functionality is not needed. Moving item to reject/close.

Item  955: conditional net discipline coercion
Item 1754: Support for auto-connecting implicit ports
Item 2343: Connect modules instances should be on lower side of ports
Item 1765: Correction of names/insertion point for connect modules.

It was felt that all four of these have a common thread and can be addressed as 
the one item. A new item will be created to cover these four. Require volunteer 
to take up and work on this item.

Item 828: Regarding light-weight conversion functions. Will be moved to 
postponed and re-investigated once we have an understand of how types and type 
conversion will work on SV-AMS.

Item 2281 - disciplines and wreal
Item 2162 - Need ability to assign 'z' state to wreal.
Item 2160 - reals and integers should be able to drive event-driven ports

All three of these items are addressing the usage and definition of wreal. With 
the moving to SV, we want to be sure we don't duplicate too much work once we 
inherit the "real valued" ports from SV. Martin has volunteered to work on the 
wreal item.

Item 936: Enhance analog/digital event control. Will delay this until we have a 
clearer understanding of how events will work in SV-AMS. Some of these new 
features may be required for the assertion work..

Item 937: Will look into this further as part of AMS Enhancements. Need to to 
be careful on the scope of where the net attributes can be modified.

Item 2566:
Item  829: VPI issues. Moving to closed. We will not be implementing any 
changes to the existing VPI feature set.

Item 2378: Deprecate wreal. Moving to closed. We won't be deprecating wreal.

Item 866: Back-Annotation support is non-existent. need to follow up if we 
really need this. If we do wish to go ahead with this, we need to investigate 
similar (if any) features in SV to make sure that we align.

Item 1854: Parameter aliases for hierarchical system parameters. This was just 
overlooked in 2.3.1. David will clean this up as part of the "cleanup" items.

Item 2159:  Contributing to a port-branch. For now we will postpone this. The 
bigger problem regarding this is that we explicitly disallow the 
contribution/assignment to any analog OOMR quantities. So even if we allowed 
contribution to port branches, the use as outlined in the Mantis item would 
still be prohibited.

Next call will be first week of December (2/3rd)
We will go through the remaining items (820, 825, 935, 934, 845, 814) and also
discuss how to move forward on the SV-AMS integration.

Regards
Dave
