node cap approximation in HSPICE

[braudelk]

The value of cdtot,cgtot,cbtot,cstot,cgs and cgd can be reported when
doing operational point analysis using HSPICE. How do they be caculated?
what is the relationship between them and how to combine these values in
my node cap approximation?

Thanks a lot

cgtot=cgs+cgb+cgd
cdtot=cdb+cgd
