FYI, Texas Instruments has several ASIC product lines containing universal PCI
inputs and outputs which ARE fully PCI compliant in both 3V and 5V
environments. If you are interested I can have our marketing department send
you additional information.

> Subject: Wanted...PCI bus 3V driver/receiver models
> I am trying to get a feel for how one might mix 3-volt level signaling and
> 5-volt level signaling PCI bus driver/receivers on a common PCI bus. I have
> IBIS models for 5-volt level signaling driver/receivers from the IBIS
> library courtesy of Intel. I would like to get models that are 3-volt level
> signaling and "5-volt compliant" (I think this just means no VCC clamping
> diode so the parts can be used with 5-volt supply) and models that are
> 3-volt level signaling ONLY (cannot be used with 5-volt supply because they
> have proction diodes?).
> I am modeling the behavior of a specific PCI bus design using Quad XTK. We
> will run at 25MHz instead of 33MHz so have more than 10ns for data to settle.
> IBIS models are preferred as they require less trouble on my part to translate
> into useable Quad models (I'm one of those u-s-e-r-s who wants models that
> plug-and-play without any effort on my part...ha). I can use Hspice models,
> if that's all that is available, and will establish non-disclosure agreements
> as necessary to get them. Thanks to any and all who are willing to help.
> P.S. I'm placing an order with ZEELAN ASAP in order to get as many
> plug-and-play models as I can afford. I've finally bit the bullet
> and decided I'll have to pay time and $ to get the models I need.
