calculator numconv function

sorry, when ı send my plot to calculator

I think you should use the analog to digital functions that were referenced in the other thread you posted in after this. The numConv is really for single valued text numbers and will convert them into a different number base. I don't think it's the right solution here.

but, I get these warning all of time.When I use zero-t  or analog plot, too, ı get these warning. 

Ok, Sır, I will change clk rate and I will test again. Thank u

Yes, as I said, this will not remove the warning, but it will stop it interpolating which is what the message is primarily alerting you to. In general, if the input waveform does not contain regularly spaced time points (and those time points coincide with the sample points for the PSD/FFT) then there will need to be interpolation to re-sample at the points needed for the PSD/FFT. This warning is a fairly generic warning that gets triggered when it's clear there is sampling/interpolation needed (there are conditional parts of the warning depending on what has to happen). With an analog waveform you can do things like use strobeperiod in the transient analysis to only have an output at a regular timestep which improves accuracy and removes the need to interpolate. In your case however, this wouldn't help - the irregular x points are coming from the fact that the bus only has a time point when the bus value changes, and hence the bus converted to analog is similar.

As I said, if you've used Zero T, you can ignore the warning - you are sampling at discrete values and so it doesn't really matter that the time steps are not regular.

I didn't say you needed to change the clock rate. I was merely saying that you need to ensure in the psd function or dft that the number of samples and the time interval you are running over results in a sample interval that corresponds to the same data rate as your bus is changing at. That data rate is presumably related to your clock frequency - it is unlikely to make sense to sample at some interval completely unrelated to the clock period. That's all I was saying.

out<2> is here MSB bit?

program  rank from msb to lsb at the top of the bit

out2 is msb bit?

ok. I found it

I'm glad you found it. Hitting help on the form makes it pretty clear, and to be honest you could experiment in less time than it took you to post the question.

Sır, my psd graph have infinity noise at the minimum level. İ can not get power spectrum density as in the like Matlab simulation. İ think that it is because of number of sample. İnput is 32 bit with 100 MHz clk frequency. But i can simulate it short time about 10u. İ don't have chance to run it long because of server. U have any idea about this problem

Please don't ask this new question on the end of the old thread (the forum guidelines ask you not to do this).

So please post a new question, with sufficient information that others can help you (I don't know where to start from your question above, since there's absolutely not enough information to understand what you're doing or what might be wrong, if anything). Perhaps somebody else will be able to figure out what you meant.
