cadence mtline issues

[madhu]

Hi all.

i am having some problems with the transmission line model of cadence
(*mtline*). It gives very high crosstalk when compared to other
transmission line tools. Mostly mtline fails to give right results for
high loss lines. I know tht h-spice w-element is based on the Method of
charactersitics and hence has some issues sometimes with low lossy
lines. What does mtline use for implementation and what are the
possible ways to circumvent these mtline issues. I would be happy to
recieve some kind of feedback from you people.. please let me know your
views...
