Hi every body,
I have designed a 10 bits DAC with cadence schematics, and I want to obtain its INL and DNL. How can I do this quickly?? is it possible with Cadence or Do I need To use other software???

thanks a lot for your help.
 

all you have to do is increment the input sequence
of the input for example 3-bit adc (000-001-010.....
and draw the output

scan you pattern.
 

Being 3-bit You canget results by manual inspection of output... but say for higher number of bits... get the difference between ideal and actual outputs and process with matlab...
