Krishna,
In hspice, you can directly plug in those s-parameters to your netlist as
an s-element. As there's no need for a w-element using one wouldn't be
right either. You can model the rest of the tracks with the w-element.
Below, I suspect you're referring to a totally different case which is
about assigning freq. dependent PUL parameters to the w-element from a
touchstone file. This can only be be used when the track parameters are
computed with a third party tool and completely irrelevant to what you're
trying to accomplish in this particular situation -if I understood your
case correctly, of course...
Regards,
Ihsan
