Is there any standard for DAC characterization (static and dynamic performance)?

IEEE has developed one for ADCs. (IEEE Std 1241-2000) (IEEE STANDARD FOR TERMINOLOGY AND TEST METHODS)

Many textbooks focus on DAC characterization after fabrication.

I am interested in a methodology for characterizing the performance on schematic level.

Static performance seem easy to determine. What about dynamic (fft measures,thd...).

thanx in advance
 

Re: DAC characterization

DAC dynamic simulations include
1. setting time simulation:
input from 0000 to 1111 (4 bits example).
find the time to settle output within 1/2LSB

2. Glitch simulation:
input from 0111 to 1111
find the glitch energy in the output waveform

3. THD simulation or SFDR simulation
sweep input from low frequency sine to 1/2Fs sin.
FFT output and get the spectrum.
calculate the THD or SFDR.
SFDR means spurious free dynamic range
