How to add a flicker noise source to a component ?

 Hello,

 I didn't find any noise source in the analogLib. Does exist a way to generate flicker or shot noise ? In the positive case, is this noise cyclostationnary (dependent of the instantaneous value of the signal) ?

    Hopefully I can reply now - I had some trouble yesterday.

    Anyway, the vsource, isource and port components have a "noisefile" parameter which can be used to add noise. If however you want it to be dependent on the value of the source, you'll probably need to write a VerilogA model since that has noise sources as part of the language (flicker_noise(), white_noise()).

    Regards,

    Andrew.
