strategy to color cross talk source question

[john23]

Hello ,given a layout with multilayer traces.On certain trace there is a high distrotion due to cross talk.
Is there a strategy to see from where the cross talk is coming from?
To color different contributions of the spectrum noise and have indiction the source of it?
Is there such a thing?
Thanks.

Of course, that's how it's done. You observe the track with disturbances on the oscilloscope and compare it with the signals on the nearby tracks.
Usually, the signal in the time domain carries more information than the spectrum.
In a real system, each signal has its characteristic features, so there is no need to "color" it, but I have sometimes injected a disturbing signal into places where it is possible and measured what part passes to the circuits sensitive to disturbances.

You should first look at layout and identify areas of maximum capacitive and/or inductive coupling between traces.
