RE: [1076.1] Proposals for new features open for discussion

Alain,

We already discussed #1 in another thread, so I will
leave that subject alone now.

Regarding #2, the S-parameter request, I was more
thinking along the lines of digital printed circuit
board (PCB) design, although RF design is certainly
a valid application.  S-parameters are often used
for describing connectors, packages, PCB traces, etc...
and there are times when it would be desirable to have
lossy interconnect models in VHDL-AMS simulations for
such components.  Unfortunately, as far as I know,
there is currently no way to use S-parameter data in
VHDL-AMS for such purposes.

At some time in the past I thought there may be ways
to write equations to convert the S-parameter data to
a transfer function that could be used with the Laplace
function, but this is not a trivial task.  This is why
I thought that adding direct support for S-parameter
data in VHDL-AMS may be a good idea.

Thanks,

Arpad

Arpad,

Here are my comments to the topics you are proposing as new features to 
the VHDL-AMS language:

1) Support for encryption has been added to the upcoming VHDL 1076-2007 
standard. As far as I know, it still has been to be ratified by the IEEE 
so it may take some time before the encryption technology is available 
to VHDL end users. Nevertheless, the 1076.1 standard will naturally 
endorse the new technology as soon as it is supported in EDA tools.

2) I proposed a process for managing proposals for new features. Your 
idea is certainly a starting point. However, if there is enough 
resonance around the topic, then the proposal should be developped 
further along the lines of the defined process.
Can you elaborate a bit further on that? Are you proposing this in the 
context of supporting RF applications in VHDL-AMS?

Best regards,
Alain
