I have had excellent success using a simple DOS-based program from Artech
House publishers. I bought it about five years ago, but find it still
applicable today (it seems that the laws of physics change more slowly than in
just a few years...ha ha). The program is Matrix Parameters for
Multiconductor Transmission lines by Djordjevic, Harrington, Sarkar, and
Bazdar. I have found typical accuracies within 2% of predictions on finished
circuit boards (verified by TDR tests).

A few simple dimensional entries in a menu-led screen will give you (in matrix
form) multi-line calculations of self and mutual inductance, capacitance,
etc., as well as compute and tabulate propagation velocity, effective
dielectric constant, and Zo.

If you want to run simulations, they offer a companion program that will
directly import the matrix parameters and allow you to connect sources and
loads and make runs to obtain crosstalk and the normal SI waveforms.
