Hmmm... I am not sure what you are after. Theory usually means
rigorous equations, proofs, etc... in the academic world, PhD
dissertations, post graduate research, etc...
Algorithms in simulation tools are usually implementations of those
theories and the equations that come with them, usually wrapped by
nice, user friendly GUI. This is how heavy-duty theory is made
practical and easy to use for the industry and the every-day life
of those who are trying make sound decisions in their design work...

Hi Pat,
We all know about transmission line theory, it describes that the signal
problem is caused by resistance mismatch and power reflection ,is there any
relationship between the transmission line theory and simulation tool's
algorithm? What is the use of transmission line theory?

Hello Zhongyong--
You have been misinformed. Specific non-uniform structures, like vias, require
3D field solvers to be modeled correctly at higher speeds, but this capability
is built directly into HyperLynx. There are many people that use HyperLynx for
10G+ designs.
You may be interested in this white paper where 12.5Gb/s signals simulated in
HyperLynx correlated with measured results:

Subject: [SI-LIST] one question about simulation tools
Hi All,
I met a question, can you help take a look?
Hyperlynx is mostly finishing about 1G signal simulation, it is not fit for
above 10G signal, other software is needed such as HFSS and CST , why can't
Hyperlynx do very high speed signal simulation, what is the simulation
algorithm and its limitations? Some people say that because the effect of high
speed signal in the Z axis direction cannot be ignored, only the
electromagnetic simulation of three-dimensional was accurate, is that right?
