RE: [IBIS-Users] RE: A newbie question

Thanks.

The customer insists on using version 3.2 @ this time.

So, I guess I'll go with Timothy's suggestions.

Hello, Lior,

This is discussed in the IBIS 4 Cookbook. If the pins are not identical
in performance, one could create two buffer models, one for each pin.

Some new options are available in IBIS 4 and 5. Various EDA tools
support these to a greater or lesser extent. You might wish to talk
with your EDA application engineers, for their recommended method to
implement your model.

The IBIS Model Review Committee is always happy to review IBIS files.

Regards,
Lynne Green
Chair, IBIS Model Review Committee

Subject: [IBIS-Users] A newbie question

Hello all.

I am writing a model for my customers.

Their requirements are:

Use version 3.2.

2 Differential Open_sink pins.

Use the IBIS full component model (i.e, not a pin model but connect the
whole block).

Use Spectre.

The question is: How do I define for the instance it's input pins (that
stimulate the two open_sink pins)?

I have looked at both Cadence manuals and yours, and could not find an
answer..

Thanks,

Lior Dagan, CAD engineer @ TranSwitch
