We should also add here ICXPro (ELDO/ADMS) simulator from Mentor Graphics that
allows pre-fit & post-fit passivity enforcement.
In this tool, passivity enforcement is not based on Hamiltonian matrices but on
another approach that can cope with large passivity violations and allows
individual choice of poles for different matrix components.
Since ELDO/ADMS combines the functions of fitter and simulator in one, it does
not need to generate spice-format model. Instead, it generates re-usable table
of poles/residues that is used for simulation directly instead of the original
Touchstone data file.

Subject: [SI-LIST] Commercial S-Parameter to Rational Approx Spice Model s/w
As a follow-on to this morning's messages regarding commercial spice model
generators enforcing passivity here is a short list of commercial s/w that has
SI application that I've just updated.
Software that claims passivity enforcement in the generated models:
------------------------------------------------------------------
Optimal Corporation WideBand Convert
TDA MeasureXtractor
Sigrity BroadBand SPICE
EMWonder EMtoSPICE
CST Microwave Studio
Cadence Allegro PCB SI 630
Does not efforce Passivity in the generated models:
----------------------------------------------------
Agilent ADS Spice Model Generator
Applied Simulation Technology SPAR
Unknown (to me) if passivity is enforced:
------------------------------------------
Ansoft Full-Wave Spice
If any of the above is in error or anyone is aware of additional software which
fits the category under discussion please pass the info along.
