Dear All,
How to simulate INL , DNL , SNR by Hspice . When I do Histogram analysis,it needs many cycle. If I design 12Bits ADC,it needs a lot of time to simulate . Have any better solution??
 

Understand the defination of DNL/INL then you can begin to simulate it. Do you know how to evaluate the DNL/INL of an actual ADC?
SNR is calculated after FFT analyse using Hspice.

I think the histogram method is very efficient method for calculating the inl dnl ..
 

can somone put some light on how actually histogram testing is done i m a bt confused in understanding it???

check out this topic , there is a document i have uploaded. it discusses histogram testing in detail.
