Hi ,
I have few signals (@ 80 Mhz & 20 Mhz) crossing the split Power
plane in the adjacent layer.

The 20 Mhz signal is diffrerential signal.The 80 Mhz is a single
ended signal.

I want to analyse the affect on Signal Integrity of these two
signals due to split plane.

I believe one need to define his stack up (Including the 
split) & then extract the layout to simulate.

I'am not too sure if the prevalent SI tools have an option
of creating split planes .

Pls suggest me a right tool to carry out this.Also , i'am
looking for a free tool to start with (even if the accuracy 
is slightly limited).

Thanks in Advance!!

Regards
Sunil.Bh
