Fangyi,

The standard says that Use_Init_Output is of Usage "Info". Info means that
is not an input to the DLL, but is information on how a DLL operates, and
what is can do, and how it expects the EDA tool to use it.

I understand why this is not clear in the current 5.0 document. It is my
intent that the modification to the 5.0 documentation that I am working on
will significantly clarify how all this is supposed to work.

My team is thoroughly reviewing my changes. I plan to incorporate a new
section on the "Reference Flows" that Arpad has been working so diligently
on.

I believe that next week Vladimir is going to give an "Admittance"
presentation. I will plan on introducing the updated spec at the meeting
after.

Subject: [ibis-macro] modifiability of AMI parameters

Hi, All;

If a parameter is of Value format and its value is specified in the .ami
file by model vendor, can EDA tools or model user modify this value? For
example, does the standard intend to let model implement two behaviors for
Use_Init_Output=true and false, and allow EDA tools to get different output
from AMI_Init by passing Use_Init_Output=true or Use_Init_Output=false in
the argument? Does a model have to support both scenarios?

I think the standard is not clear about whether the parameters are used by
models to instruct EDA tools how to call the model, or used by EDA tools to
instruct the models how to function.

Thanks,
Fangyi
