how to measure dnl of a dac using ahdllib
Hello . I am trying to get the DNL from 10 bit sar adc ? I am using , cadence library "ahdlLib , dac_10bit_ideal " to convert the 10 bit ADC ramping output " D9
0 to analog signal . Then using , " cadence library " ahdlLib , dac_dnl_10bit " to get the DNL of the ADC ? It supposed to output a histogram file or someting . But I dont see any file ? I actually change the original , ahdlLib dac_dnl_8bit to 10 bit dnl .
How does , cadence ahdlLib , dac_dnl_8bit work ? Have anyone used it before ?
I able to get dac output vout , attached picture but how to measure dnl ?
Regards.
