HI All,
I was wondering whether 10Gig differntial routing was better handled
when routed in stripline or microstrip(standard FR4; length < 1 inch).
Also please let us know if a loose coupling would help with std. FR-4.

Please ignore the previous message and the terrible English!
Sorry for the cryptic Object!
I tried some simulations using W element lines.
In the first case the RLGC matrix was generated by the internal Hspice =
=3D
2D EM simulator, in the second case the RLGC matrix was generated by =3D
XFX.
Losses in case one are larger than in case two. Materials and geometry =
=3D
are the same, as well ro and tan.
My questions:
1) did you noticed the same behaviour? is it always true, I mean for all
=3D geometries?
2) why?
3) who is right? (Hspice EM simulator seems more similar to measures)
Best regards, Merry Christmas and Happy New Year
Giovanni
