How to set noise spectrum to an input of the device?

Hi, all.

I'm working in Cadence IC 6.1.
In my project I need to set noise spectrum to an input of my device.
Did you know, is it possible or not?
And if it possible, how can I do this( maybe, special signal generator or some option in analysis )?

Thanks in advance.

A noise spectrum isn't a signal. It's one of many possible parameters of a signal. You may want to supply a pseudo noise signal with specific parameters in timing analysis.

I want to set RMS noise on an input of the scheme.

There is a noise generator in analogLib..
You may set the rms noise voltage in properties menu..

Thank you, but could you know name of this noise generator in analogLib?
I know that some of generators in analogLib allows to set noise by noiseFile.
And how to form data in this file? Also, can I set noise power band?
