Hi Arpad,
Thanks for following up on this.
My point here is that we should not be needing "Supporting_Files" as a key ami
parameter. Such needed files can always become part of Model_Specific section
and can have any parameter-name depending on how ami-code wants to use such
files .
If these supporting files are NOT to be used by AMI-code but are meant for use
for Analog-channel characterization (as it seems to be the case for the example
where s4p files look to be representing package or onchip sparams) then these
have to be tackled in EXTERNAL_MODEL / ISS - Use of such s-param files in ami
is an overkill and defeats the purpose of ISS.

Kukal,
Correct me if I misunderstood your comments on BIRD 121.
To follow up on my last reply I brought the question up
in one of the last ATM meetings and found out that the
"Supporting_Files" AMI parameter can have file and/or
directory entries.
| "Supporting_Files" is an AMI parameter of Type String, Usage Info, Format List
| that contains a list of the files the model requires in addition to the DLL or
| shared object file. In the specified List, each String is the relative path
| from the .ibs file directory to one supporting file or directory.
|
| Example:
|
| (Supporting_Files (Usage Info)(Type String)
| (List "my_stuff_dir" "m1.s4p" "m2.s4p" "m3.s4p")
| (Description "Additional files that support this model")
| )
So this parameter may be used as a "search path" as well as
"file pointer".
Please let us know if you have more questions or comments on
this topic.
Thanks,
Arpad

Kukal,
Thanks for the clarification.
My understanding of BIRD 121 is that this is the equivalent of
the "search path" in HSPICE or similar tools. This is not where
the files are instantiated. In light of that, we may need to
discuss whether it is appropriate to include file names instead
of just path names, but we didn't get to a detailed discussion
on this BIRD yet.
Thanks,
Arpad

Hi Arpad,
What I meant is that the BIRD116 covers s-parameters as part of [External
Model] and that is the right place-holder.
Even if AMI code needs to work in conjunction with Spice files (or s-param
files), then those files need to be either under [External Model] OR should be
referred through model-parameter (Not reserved) in .ami file.
The inclusion of s-parameters as part of AMI section (.ami file) with use of
'Supporting_Files' Reserved-keyword is not required.
AMI should not hold anything other than ami-code related parameters.

Kukal,
I would like you to clarify what you are saying here
because it is not clear what you are referring to in
your last sentence:
"we do not need this anymore"
Does this refer to BIRD 121 mentioned in the subject
line, or are you talking about not needing BIRD 116?
Thanks,
Arpad

Hi,
All supporting files (s-params or otherwise) should be scope of [External
Model] -
These s-param files do not have anything to do with AMI C-code. The fact that
BIRD116 covers s-params as part of [External Model] and allows working of same
in conjunction with AMI, we do not need this anymore.
thoughts?
