Hi:
Spcie or hspice gives noise contribution of every componet.
But I want to kown the noise contribution of every subcircuit . Can
anybody give any suggestion ?
 

Hierachical functions on the spice results is an often feature asked for.

Is is not evaluated within spice but you can write scripts which calculate the numbers.

Also power, node activity, ... are important hierachical numbers. I think power is implemented in some simulators.
