[SI-LIST] Re: Signal crossing Split plane

Sunil,

I have been using SONNET LITE for this type of simulation. Being a
free version of SONNET it is limited but can still provide plenty of
insight into problems. The limitations are 2 metal layers plus a "box"
bottom and top and three dielectric layers. For the split plane
analysys this is no problem. The data is frequency domain only, as far
as I know. To view the circuit in the time domain I build a SPICE
model.
