RE: [SI-LIST] : Tools for high-speed interconnect designHassan, Charles,

HFSS V8 will have a number of enhancements that make it a full-wave
spice tool.
The enhancements that will most directly focus on SI applications
include Modal-to-modal transformations, which enable a structure to have
multiple coupled conductors at the ports (or terminals), Spice model
export (to Maxwell Spice, PSPICE and HSPICE), lumped RLC elements,
and interpolative discrete sweeps, which will allow extremely large
problems to run faster and smaller and allow for very accurate emissions

I am not sure when V8 will be released - I believe the scheduled date is
around the end of the year, but it has not been announced yet.

  "Modes to nodes" thing won't give you a SPICE model from the way I
understood that concept from the Ansoft people and from my own past
research. I understood it to be a technique of coupling (interfacing)
traditional SPICE-based electrical circuit (nodal) simulation with 3D EM
field (modal) simulation. In this technique the models of the
are implicitly generated and utilised. The generated interconnect models
would mean nothing to external SPICE-based simulators. Ansoft people may
correct me if I'm wrong.

  And BTW, is Ansoft HFSS 8 already available?

  Ansofts HFSS version 8 translates modes to nodes , in other words you
  a fully coulped SPICE model of the device of interest to a very high

  Thank you.
