how can i do fft in analog artist?

thanks a lot

Don't you mean:

What kind of FFT can I simulate in Analog Artist?

( look in the examples directories for a good tutorial on this! )

Greetings,

A few additional comments,
1) Spectre's Fourier Analysis is based on the Fourier Integral
and can be accessed in ADE by using the fourier component
from analogLib.
2) Not all the features of Spectre's Fourier Analysis have been
implemented in ADE. The fourier component assumes the fundamental
frequency is the first tone. For characterizing op-amps distortion
this is not an issue. If you want to look ADC or DAC, please
let me know.
3) The FFT in ADE is in the Calculator, the dft function, and the
tutorials should provide all the information you need.

The Fourier Analysis is discussed in detail in Ken Kundert's
book on SPICE and Spectre, as well as, in paper he presented
at CICC in 1994.

Really thank you very much.
and I have checked the docs in cadence install directory, but I didn't
find anything which elaborate on this topic.
and can anyone give me an example to setup the analog artist for
testing the SNDR of a ADC?
thank you, i am a newbie
