Not also that NIST offers free their TDNACAL program which works on
a PC with a GPIB connected to either the TEK or the HP TDR. If you can
use S-parameter files in your simulator this is great.

In addition to what Scott said, differential TDR measurements will make the
task even easier. Furthermore, there is commercial software available that
extracts package interconnect models from TDR data.
