Paul,
Sorry for the delay in answering your message, but I am
trying to get this library finished franticly... I am
getting close now, and I will look at your GUI as soon
as I am done.
I would like to make a request to you. We need another
script, or some code added to this one to do a similar
extraction for the VHDL-A(MS) version of the library.
I am attaching a file as an example. The rules are
simple:
Put the name of the parameter on a line by itself, and
I mean it BY ITSELF, nothing before, nothing after
(except for any of these four: CRLF, CR, LF, LFCR),
and then put the value on the line immediately following
it. The line with the value can have blank spaces or
tabs before and/or after the number. To be safe, for now
the number should only use exponential notation. After
the value you can have blank lines or any other text before
the new variable name. If it is an array, each element
must be on a new line, without any blank lines between the
rows. The array ends with anything that is not a number,
blank line, any text, a new variable name (or EOF).
Regarding your idea of reading the template for the extraction,
I think it is a nice idea. Anything that can make the life of
a modeler easier is good.
I am not aware of any more templates other than the ones we
distributed in the macro model group.
Regarding the scaling element, bring it up in a meeting and
we can discuss it there. (Or address this email forum, and not
me directly...). We can add anything that is needed and is
useful to the library, but we need consensus for doing it...
Thanks,
Arpad

Subject: [ibis-macro] IBIS-to-AMS script update
Hi Arpad,
I've added a GUI (Perl/Tk) to the IBIS-to-AMS script. When the user selects the
IBIS
file, it lists the models in the file. Once the user selects a model, it asks
for the
corner and creates a Verilog-A .dat file with the relevent information. (To run
it type:
"perl conv.pl") Needless to say, its quite simple at this point.
I'm thinking of updating the script so that it can handle templates as well. For
example, if a model maker wants to create a pre-emphasis AMS model, they would
select
the relevent template and the GUI would request the input data/ibisfiles
interactively.
Is this a good approach to creating a more complete IBIS-to-AMS converter?
Could you please let me know if there are anymore templates available (other
than the
pre-emphasis buffer)? I'd like to create the template for an LVDS buffer at
some point;
the problem is that I fail to see how the AMS modeling technique helps in this
case.
Could you give me some pointers?
I have a suggestion for an additional macro library element. Right now the
scaling is
done my using 8 current sources. Could we lump them into a library element,
since
scaling would be frequently used?
Regards,
Paul
