One of our engineers is working on some ludicrously fast signaling that
customers (IMHO foolishly) want to do on FR-4 instead of something
sensible. Then again, I suppose I shouldn't complain if they save money
on the material and spend it on the silicon...

Anyway, rather than reinvent the wheel he's looking for some coupled
differential line models for ~110 ohm FR-4 (the usual 5 mil traces etc.)
Which leads me to suspect that there's a need for a prior-art repository.

In the meantime, does anyone have reasonable lossy models that they
want to contribute?
