Minutes:
========================================
Meeting started 10minutes late. We all agreed that all following
meetings will start on time. We will not wait for latecomers to start
the meetings.
Joao assigned task of taking minutes.
Stuart reopened discussion on the goals of this sub-committee, as we
did not have a voted agreement on this subject last meeting. After
discussion we all voted and unanimously agreed on the following:
1- this sub-committee cannot deliver enhancements to PLI/VPI to cater
for the enhancements and/or changes to Verilog introduced by
SystemVerilog on the time-frame given, for the following reasons:
a) time constraints: the task is considerable, touching on all
facets of the enhancements/modifications introduced by
SystemVerilog.
b) dependencies: the task can be achieved only once the language
stabilizes. As this is being performed by different
sub-committees, there is an inter-comittee dependency.
2- this sub-commitee will defer any work related to PLI/VPI
definition. We consider that this task is more appropriately
handled by each and every group that is modifying the language; if
assigned to us, the issues raised in point 1) need to be addressed.
3- with the presumption that VPI will be reassigned/deferred, this
committee believes its first priority/task consists of defining the
direct foreign language interface (directC like interface) to
SystemVerilog.
All attendees voted, all in agreement.
NOTES: (led by Peter)
The above does not mean to imply that we do not believe VPI/PLI to
be important. We do not believe that SystemVerilog can be considered
complete without defining the necessary extensions to
PLI/VPI. However, due to the aforementioned issues, we do not
believe we are the appropriate committee to tackle such a
definition.
ACTION ITEM: Ghassan: to communicate the above agreement to the primary
SystemVerilog committee and/or Vassilius (as appropriate). We need to
ensure that group as a whole understands what this committee will be
doing and to ensure that VPI/PLI definition will not be dropped. We
also need confirmation that the agreement we've reached is acceptable
to the primary committee.
Then we discussed the process by which we will defined the direct
foreign language interface. Following Stuart's recommendation, we will
first agree on the requirements that this interface has to satisfy.
ACTION ITEMS:
Andrzej: send to reflector the Synopsys understanding of requirements
Peter: send to reflector the CoDesign understanding of requirements
[action items assigned to companies that already possess a similar
interface, drawing from their experience and the requirements that led
them to develop such interfaces in the first place]
