[SI-LIST] SI models at MGH speeds

Hi,

Can anyone tell me why it is difficult to generate IBIS models for
mutli-giga hz devices. Most of the vendors give us HSPICE models. Is it
something to do with difficulty in accurate characterisation of V/I
curve at such high frequencies (>5GHz)?

In any case are HSPICE models also the correct solution? Presuming such
interfaces also have pre-emphasis and de-emphasis. Cadence suggests the
use of macromodels for MGH applications however, is it possible to
convert HSPICE models to accurate macromodels for simulation in
SPECCTRAQUEST for >5GHz application?

Thanks
Sunil
