Hi Ambrish,
I recall some e-mail exchanges on this subject several months ago, but I
do not remember the conclusions.
What you are saying sounds like another flaw in the current spec. I
would expect the input/output DLL strings to conform COMPLETELY to the
parameter tree hierarchy specified in the *.ami file. The reason is
simple: by the principles of a parameter tree we can have exactly the
same leaf or sub-branch name in two or more branches. Therefore,
stripping a branch (removing it and bringing the entire sub-tree one
level up) should not be allowed. Any exceptions from this rule must be
explicitly stated.
So, are you saying that stripping the two branches (Reserved_Parameters
and Model_Specific) is a de-facto standard?

input parameter string
Hi Fangyi,
It will be
(mySampleAMI
(ntap 5)
)
The keywords Reserved_Parameters and Model_Specific are meant for
organizing the parameters in the ami file only and not supposed to be
passed to the model.
Thanks,
Ambrish.

Subject: [ibis-macro] question on Model_Specific branch name in input
parameter string
Hi, Experts;
Based on the current AMI standard should the Model_Specific branch name
appear in the input parameter string to the AMI Init call? For example,
for the following .ami file
(mySampleAMI
(Reserved_Parameters
...
)
(Model_Specific
(ntap (Usage In) (Type Integer) (Format Value 5))
)
)
Shall the input parameter string be
(mySampleAMI
(Model_Specific
(ntap 5)
)
)
or
(mySampleAMI
(ntap 5)
)
I understand that if the proposed BIRD is accepted then Model_Specific
and Reserved_Parameter branchs will disappear. But for models written
based on the current standard it's not clear which format EDA tools
should feed to models.
Thanks in advance.
Fangyi
