Arpad Muranyi hosted the meeting.

No patents were declared.  No opens were declared.

Arpad:  Should we continue with the meeting, since most of those who requested the presentation prepared for the meeting are not present?

Walter: Yes, it would be still useful to review the pre-layout examples in BIRD 163 style.

Arpad:  Shared the presentation slides and discussed each slide.

Walter commenting on the last slide:  We need to support coupled pre-layout models, and agreed that this will require user intervention.

Arpad:  This is also a question about how much automation we expect from IBIS, and how useful it is if the user has to do things manually.

Bob:  Can parameters be passed?
Arpad: Yes, the parameter passing features in IBIS v6.0 are all applicable to these examples, and BIRD 165 has additional flexibility for passing parameters individually to each instance of an [External Circuit] from the [Circuit Call] keyword.

Bob:  Can Touchstone files be instantiated directly without going through the IBIS_ISS subcircuit wrapper?

Arpad: No, these BIRDs do not address that.  BIRD 144 addressed that topic but it was rejected by the IBIS Open Forum.  If this feature is needed, we can address it with a new BIRD.

Walter:  Strings should probably be enclosed in single quotes in the examples.

Arpad shared the IBIS_ISS specification on the screen to look up the proper syntax of string parameters.

Arpad:  What are the next steps?  What decision(s) have to be made to progress with these discussions?

Walter:  We need to decide whether we want the SiSoft proposal using the [Define Package] approach or the Mentor/Cadence BIRDs with the [External Circuit] syntax.  The decision should be made in the Interconnect meetings, brought to the ATM meetings, and then the ATM Task Group can make a final recommendation to the IBIS Open Forum.

The meeting ended at 8:55 a.m. Pacific time.


AR: Arpad:  Email the presentation to the Interconnect reflector and ask Mike M. to post the presentation.
