Hi~~all
I have a ADC , and want to simulate it SNR & SNDR
but found there is no method can directly simulate it , and i use newest cadence spctre the calculator is no contain snr function.
I only have result of FFT , i avoid translate data to matlab because too larger,
so is anybody has method to calculate SNR & SDNR in cadence spectre ?
thx
 

The best way is to translate tha data to matlab
 

i think can use calculator function psd to perform SNDR,
10*log[(integration fundamental signal)/(integration all interesting band - integration fundamental signal)]
 

Do FFT then calculate SNR and SNDR
 

Using dft of calculator function,and you can get HD3 and SNDR.
 

use matlab it is the best option
 

of course, you also can use matlab if you post the data to matlab.
