Hi Jim / vhdl-200x,
Unfortunately I won't be able to dial into the meeting tomorrow. However
I would like to circulate a couple of points I would contribute if able
to attend.
Firstly, I am happy with the minutes from the last meeting.
Secondly, regarding interfacing to other languages I feel it is
important to clarify what we are expecting from additional interfaces to
scripting languages (ignoring the discussion about SystemVerilog/System
C TLM).
What are we expecting that cannot currently be implemented using VHPI?
If there are any deficiencies in VHPI should they not rather be
addressed by improving VHPI rather than creating additional interfaces
(with the associated problems of pushing tool vendors to support them)?
Is it the responsibility of VHDL to support multiple language interfaces
(all of the scripting languages mentioned support some form of C based
interface or extension capability)?
I suspect that much of what is being requested is already possible using
VHPI. For background reading refer to pyHVL
(http://pyhvl.sourceforge.net/) which provides a python interface
through the Verilog PLI. It is possible to do the same thing with VHPI.
Finally, regarding general language change requirements, please consider
hierarchical library/package implementation such that the following VHDL
code is valid:
library mylibrary.sublibrary1.sublibrary2;
use sublibrary2.mypackage.object;
or even better adopt something similar to python by allowing arbitrary
renaming of namespace objects on import:
library this.that.theother as nicename;
use nicename.thingy.footype as foo;
..
signal my_foo : foo;
Thanks,
Chris Higgs
