I want to use the DNL/INL AHDL blocks in ahdllib in Cadence to measure the DNL/INL of an ADC.

I use the ideal DAC to convert to digital then add the DNL or INL ahdlLIb block and a file is outputted ?

What is outputted in these files for DNL/INL ? Do I have to post-process the outputs?

If anyone has done this using the ahdlLib blocks please let me know.

I know in the latest versions of Cadence DFII (IC6.17), you can generate histogram plots using VIVA Waveform Viewer, is this helpful to generate INL/DNL ?

Can I do post processing directly in Cadence on this histogram or do I have to output the file from Cadence and then use MATLAB for post - processing ?

Thank you.
