Re: How to deal with analog devices?

Hi Chen,

  Here is my take. There are three major classifications for
models to get into a board level signal integrity evaluation.

  First, IBIS models for buffer modelling.

  Second, analog and jelly bean parts such as
   resistors, capacitors, switches, etc. are
   typically modelled as very small spice like models.
   (Each vendor has their own little language parsers)

  Third, connectors. Since IBIS support is supposedly on
  the way, the signal integrity engine providers have
  to currently offer their own language modelling support.
  It is usually a primary RLC matrix with mutual inductance and
  mutual capacitance specifications for the pins.

 Good question!
