Re: [vhdl-200x] A Challenge

I (and my team) would be very interested in the interfaces and 
directionality definitions as mentioned in previous ideas like 
http://www.eda-twiki.org/cgi-bin/view.cgi/P1076/InterfaceAttributes. 

I work on a what is effectively a transpiler that generates VHDL from 
various high-level languages. The VHDL we generate is very complicated and 
we have to jump through hoops to turn dataflow-esque form into a 
process-oriented implementation that has many complicated record types 
flowing between components. 

Our compiler must decompose these high-level, nested "record" types into 
parallel input and output paths that make the VHDL (and therefore 
debugging waveforms, etc.) quite ugly.

Given the proposals such as the one above our compiler could keep these 
structures intact and emit varying flavors of them for the directionality 
of the connections. This should be a win-win all around.

Cheers!

I will really like to see at least one of the proposals on block 
interfaces get through to the next revision. I'm particularly interested 
in John's conjugated ports proposal:
http://www.eda-twiki.org/cgi-bin/view.cgi/P1076/InterfaceAttributes

Cheers, Dan

Hi Jim, Hi All

I don't know if this appeal concerns features that are not in wiki 
proposals
or not on the voting list. I assume that If It's not on voting list - it 
was
not considered to work on it.

IMHO very important feature would be DPI for VHDL:
http://www.eda-twiki.org/cgi-bin/view.cgi/P1076/DpiProposal

Even in basic variation of proposal  (only DPI_C) i would be usefull and
gives user many new opportunities (simple and fast access to golden model,
Xtors, own library or different tool),

Best Regards,
Radek

Hi,
Our current PAR expires at the end of 2015.  I have applied for an
extension, which we should be able to get.

OTOH, if we could consider getting a set of work done and balloted by 
then.
What I would like you to do then is look over the proposals.  Are there 
one
to three that would really make a difference
in your work, that are minimal risk of unintended side effects, and that 
you
would perhaps be willing to help work on the LCS for?

Please reply to this with your list and why you need the item.  We can 
talk
about it in the meeting  on Thursday.

Best Regards,
Jim
