How to include noise file in cadence schematic editor ?

[Shakeel]

Hi Fellows:

I am trying to include a noise file from measured data. The file is in
the following format:

100.00 2.54
200.00 3.45
..
..
..
..


The first column is FREQ and the second is Noise. I am unable to put
this info into psin block. After putting all this there, the output
does not show anything in the AC plot for the noise.

Any suggestions ?

THanks,
Shakeel

Shakeel,

Components such as port (use this rather than psin, since it is easier to use
and more comprehensive) and vsource from analogLib have an option to enter
a noise file.

Corresponds to the "noisefile" parameter on the spectre port and vsource
components.

It's also possible to enter the frequency/value pairs on the form.

Also, I assume you didn't mean the AC plot, but the noise plot...

Andrew.
