Hi,
I've recently returned to consluting work and have the opportunity to
release some tools I developed a while ago into the public domain and wanted
to share some of them with the SI List.
I developed an impedance transmission line calculator that basically
provides a nice litte GUI interface to calculating PCB stackup impedance
using standard microstrip/stripline impedance formulas. You can also graph
impedance versus different parameters like trace width. As a bonus there is
support for open source 2D field sovler to calcuate L and C for differential
and coupled tranmission lines (sorry no lossy models) and if you have an
HSPICE license it can interface with the built-in field solver.
It was written in Java so you will need to have Java installed on your
computer. It is free to use for both commerical and personal use and can be
downloaded at http://www.signalbytestech.com/wSolver.html.
Hopefully someone will find this tool useful in their work.
Best,
