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. rgds ..kukal ________________________________ From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Muranyi, Arpad Sent: Thursday, January 13, 2011 10:41 PM To: IBIS-ATM Subject: [ibis-macro] Re: BIRD121: New AMI params (Supporting_Files) in context of BIRD116 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?

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? rgds ..kukal Taranjit Kukal | Product Engineering Architect P: 91 120 3984000 www.cadence.com<http://www.cadence.com/>
