RE: Support of IBIS and IMIC

As far as I know, HSPICE supports IMIC also. To what extent, I don't know.

   Almost all major CAE vendors support IBIS V3.2 -- for a partial listing
 go to the IBIS web site and look at the roster page. As for supported
 features, there are a core set of features (multi-driver models, submodels,
 EBD files are the ones that come to mind immediately) that models providers
 have requested and most CAE vendors support. However, for specific details
 on what each tool supports you should contact each individual CAE vendor.

 Some tools will read an IBIS data file directly, other convert it into
 their own model format.

  Not that I'm aware of.

  I don't know of any US company that is providing IMIC models. I believe
 some Japanese companies are, but again, you will have to inquire directly.

   IBIS is seriously considering incorporating both nodal type descriptions
 and general purpose behavioral elements into the standard. This is to
support
 package modeling (i.e. allow the user to build models that accurately
reflect
 the effects of power and ground distribution on SSO noise) as well as
receiver
 modeling. At this time, IBIS models are not intended to support EMI type
 simulators.
 
 In general, I view IMIC as filling a different role than IBIS. IMIC is
basically
a way to describe a transistor level circuit without revealing process
information,
but it is still targeted towards circuit type simulators. IBIS is targeted
towards
the behavioral, system level, simulator.
