[SI-LIST] HSPICE 2003.03 W-element concern

Hello,
I was told by a very experienced college of mine, who was told by a
HSPICE rep, that the W-element in HSPICE version 2003.03 requires and
additional command to be accurate for long lossy transmission lines, (ie
backplane or cables). Specifically one needs to add "delayopt=1" to the
end of the w-element statement.
I have run a few different simulations and I do see a difference when
the delayopt is used. More importantly, it changes delay and the impedance
profile. This concerns me, especially since there is no documentation
of this "feature/bug" in any of the 2003.03 manuals.
So, does any one out there have any experience with this addition to the
w-element command.? If so what is it doing differently?
I have a couple of emails into synopsys, but have yet to get feedback.
so your comments will be greatly appreciated.
Regards
-Ed Sayre
