Hello SI-People:
We have now several times encountered differences in results from other
modelling packages and results from HSPICE w-element models for applications
involving fairly long striplines > 30cm on FR4 and GETEK with 2.5Gbps
signals with ~100ps edge rates. The W-element model appears to give lower
loss than the other techniques. Typical track widths are 6-8 mils with
100Ohm loosely coupled differential pairs.
Avant! claims the W-element method is accurate without providing a paper
showing how it was validated.
How does the rest of the SI community feel about the accuracy of the
W-element model?
Thanks in advance,
Kai Keskinen
