[SI-LIST] Parasitic extraction and correlation to package delay measurement

I would like to solicit you opinions on parasitic extraction using such
tools as Ansoft TPA and others.
Have you conducted any correlation studies to see how accurate the
extraction is?

Can such tools predict parasitics that provide delays to match real
measurements to for example 5 psec?
We have had trouble getting good correlation results and was wondering if
others have the same trouble.
