How can I give Addictive White Gaussian Noise(AWGN) as an INPUT?

Surya Kiran

Hi,

I am Using Cadence Virtuoso 6.1

I am designing front end design and I need to add an AWGN as an input to verify it, I am using Spectre Simulator for this design.

Please help me with this.

Thank you

    Andrew, 

    Thank you for your reply. 

    I am using transient analysis and I want to check my design by giving Addictive white gaussian noise(AWGN) as an input.

    When I select Vsource from the analoglib, it is not giving me all those parameter you mentioned above

    Here I don't understand what to choose in Noise entry method (File or Noise/Frequency points).

    and the above model You gave is for the noise analysis, but what changes do I have to make to use it in transient analysis and where should I include $rdist_normal() in the Code.

    Surya.
