i want to simulation for divide by 128/129 counter
and want to see its power spectral density how it look can any one help me on this topic
i am having problem in choosing voltage source for that simulation

its giving an error when i do Qpss analsis ... it saying missing fund some thing like this

Just use PSS simulation, set the fundamental frequency as the output frequency of the divider. Check the results in spectrum domain. QPSS simulation is not needed.
