RE: [IBIS-Users] IBIS - AMI - questions

Todd,

Thank you for correcting me, and I apologize for
the mis-statement.  It was not intentional.

After your last posting I did find the .ami file
in your toolkit and I agree, it does indeed follow
the IBIS-AMI specification.  What mislead me was
that the batch files that come with the toolkit
seem to make no use of that .ami file, and as a
consequence I never experimented with using it...

Thanks,

Arpad

Arpad,

Your statement

"The SiSoft example uses a "proprietary" CSV file format for entering 
the parameters"

is incorrect.  I can see how you might think that if you hadn't read the 
kit doc completely, but the statement is still incorrect.

The .ami file included in the SiSoft kit is a full and proper .ami 
file.  The utility ami2csv is used to convert the .ami data to the .csv 
format that the standalone simulator uses.  Thus, the use model is 
intended to be:

.ami file --> ami2csv --> standalone simulation test bench

Yes, the standalone simulator does not read the .ami file directly ... 
no one ever promised that it would.  Nonetheless, the SiSoft toolkit 
provides a defined mechanism for utilizing compliant .ami files.

Todd.
