Hi!

Sorry for my mistake.The signal operating frequencies is under 30M and the Tr
of device is over 8ns in the double-side PWB.So maybe called low-speed.In
fact,it should be considered as a transmission line in sometimes.It is
difficult to simulate these transmission lines because they have no a entire
ground/power plane.How to abstract the transmission lines model in
double-sides PWB?Maybe you can use the Ansoft's Spicelink,but it can't
abstract a long trace because the database is too big.Who can tell me what
kinds of solutions or yours suggests?

Regards,

Rachild
