Now they have yet another excuse. "We don't have enough demand for IBIS
models, and the EDA tool vendors don't support 3.x."
Do I give up and just make major simplifying assumptions, without
knowing exactly how that would affect accuracy? Is it time for DFWTMTP?
(Design For Way Too Many Termination Parts)
It would be nice if manufacturers included all the data necessary to
generate IBIS models inside the data book. Several come close, but not
quite all the way, by including driver and pullup VI curves. Almost
none of them spec resistive rise time, so I have to pick something that
seems reasonable until I get a good answer from the vendor (possibly
after teaching them what I'm asking for). I've seen vendors spec "Slew
rate limitted" drivers without saying what they limitted it to. Those
are a little difficult to model.
[end rant]
I'm assuming most people who've attempted to use and acquire IBIS models
have had similar experiences. True?
