How to add a flicker noise source to a component ?

wighou

 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) ?

     Hi,

    OK, I read a little bit about Verilog-A. The functions that you cited (flicker_noise(), white_noise()) are only active in small-signal noise analysis. To clarify, the noise has to be considered as a small-signal in the analysis but the circuit can be analysed with large-signal, isn't it ? So can I use this function in an oscillator phase noise analysis (pnoise after a pss) ? 

    With a Verilog-A block, can I use the Spectre simulator or I have to use SpectreVerilog ?

    Regards,

    Emmanuel
