Transient Noise Simulation in Spectre

SwatiSingh

I am running Transient Noise simulation in Spectre giving multiple runs . How can  I calculate the  rms value of noise at a particular time ?

    Yaser,

    Yes, it's based on the circuit components. If both noisefmax and noisefmin are specified, it will shape the noise between the two. If only noisefmax is given, it assumes the noise is white based on whatever magnitude it is at noisefmax (see the documentation for more detail). At the very least, look at "spectre -h tran" for details on the noise* parameters.

    Regards,

    Andrew.
