Abstract: A method for determining the sensitivity of an analog output node of a mixed-signal module on a system on a chip (SoC) to noise coupling on the analog input nodes of the mixed-signal module includes (i) selecting an IP block for testing, (ii) selecting the output node, (iii) compiling a list of input nodes for testing, (iv) for each input node of the list, providing excitation signals at different frequencies, (v) for each provided excitation signal, determining the output node's noise sensitivity, and (vi) if any individual and/or cumulative noise sensitivity result exceeds a preset threshold, then modifying the SoC design to take corrective action.
