Hi Brett,

there is something out called the EMC-Workbench, which provides
a need graphical user interface for project administration as well
as network analysis. It comes with all kinds of software tools,
starting from calculation of the TL parameters, a transmission line
simulator tailored for reflection and x-talk analysis, a MOM code
for radiation prediction. It is connected to a component library,
and has all kinds of visualization tools for results and layout.
For parameter studies one may even alter the network properties
in something that resembles a graphical editor.

The procedure somehow is selection of a network or interconnect via
its name by mouse click, selection of analysis method; if one is
lucky and the layout is appropriately specified, it finds the attached
components, if not one has to attach models from a library. Then
one has to specify the excitation function (clock, magnitude,
duty cycle - rise and fall times are due to the library model).
Subsequently the calculation is and the results are displayed.

More information may be found on their web site
