IBIS Questions

Hi,

I had several questions regarding IBIS.

1) Is IBIS able to model SSTL2 and SSTL3?
2) Our company has created I/Os that are proprietary. They are
        differential. They also need to be AC coupled. As a result,
        series capacitors must be placed between the driver and receiver.
        Our I/Os are designed to drive and receive A.C. PECL signals. Can
        IBIS be used to model these I/Os? The D.C. levels of our drivers
        are not PECL levels.
3) Can't IBIS model any I/O since it just utilizes I-V curves? Is
        the question regarding generating IBIS models just a question
regarding
        how many I-V tables need to be generated and the loading conditions
        when generating the "Rising and Falling Waveform"? Is this why IBIS
        can support only certain I/Os (TTL, ECL, etc).
4) Isn't the "Ramp" data and the "Rising and Falling Waveform" redundant?
        Aren't both used to determine rise and fall times?
5) Since IBIS uses I-V curves, can it model transient or hysteresis effects
of
        drivers and receivers? For example, if a driver initially drives
        6 ma at 2 volts (logic high). After the driver stabilizes at the
logic
        high (2 volt), then it drives .05 ma. It seems IBIS can't model
this
        type of driver. Is this true? I assume that is why all packaging
elements
        (capacitors and inductors) must be separated from the output driver.

6) Are there any good books or documents on IBIS, how it works, and how to
create accurate IBIS
        models?
7) Is there anything preventing IBIS from accurately modelling high speed
circuits (rise/fall
        times=100 ps)?
