Extracting coupling caps from SPEF file

[Koustav]

Hello everybody,

I am trying to extract the coupling capacitance and hence estimate
the cross talk noise. I know that by running Fire-n-Ice on the placed
and routed DEF file I can extract the SPEF and I have read that you
could write a perl script to process this SPEF file and get the
coupling cap for a certain number of aggressor nets. Does anybody have
any such script that I could borrow? Or perhaps some pointers where I
can obtain this. I will really appreciate any kind of help.

Thanks,
Koustav
