parasitic capacitance calculation of interconnects

[eng_ema]

Hi everybody,

i was working on a layout of a boost converter control
i finished it but now i am trying to calculate the parasitic capacitance of interconnects of power switches
after searching i found that i can do that with software like "Maxwell" or "fastcap"
but i don't now if it possible for MOSFET with large number of fingers

so is there any one now about this

thanks in advance
