IBIS at >400MHz

In future designs, we plan to use interfaces that
reach beyond 400 MHz. As I think about the tools
that we need to help us successfully design at that
speed, simulation is going to be a big part of it.
But I am concerned that IBIS descriptions and
simulation techniques may not be adequate to accurately
simulate at that speed. Perhaps SPICE simulation
will be required.

Should IBIS based simulators be capable of accurate
simulation at speed of 400MHz to 1000MHz?

When device parasitics play a larger part of the
equation, is IBIS sufficiently robust to accurately
describe these parasitics?

What are the key factors to consider when simulating
at these higher frequencies?

What are your thoughts?
