If I understand you definition of 2.5 D software, that is, a 2D analysis of
a cross-section of PCB which then is extended in the length demension
assuming consistent transverse fields, then just about all of the modern
(and even more ancient) solvers and simulators use this approach. Off the
top of my head: (no order, some tool names some company names) XTK,
Hyperlynx, Ansoft, Spectrequest, Quantic, XSPICE (where X = H,Q,P,N,<NULL>,
and doubtess other letters). Then if you want some of the later generation
tools that are claiming 3D, look at sigrity.
My apologies for the many exclusions. Take a look at the IBIS web page for
more ideas.
regards,
jon

Arpad,
Thanks for your reply. There is a general feeling that IBIS is not very =
accurate for multi-gigabit/s data streams and it is a pain to =
incorporate features like pre-emphasis etc. Any thoughts on this.=20

Subject: [SI-LIST] Behavioral modeling
All,
What is a good way to do behavioral modeling? Running SPICE for high =3D
speed simulations ( 3 - 4 Gbps) can be very time consuming especially =
=3D
with backplane,via, connector models etc. I have heard that VHDL AMS and =
=3D
Cadence's DML are options that can used with their tools. Is there a =3D
simpler way to do it with reasonable accuracy?
Stuff that can be imported into SPICE tools and that will save on =3D
simulation times.
=3D20
Thanks for your thoughts.
