Contents of hbnoise_xf results directory

Michele Ancis

Hi, from within Virtuoso 6.1.6 , MMSIM 13.1 ISR10

I am performing an hbnoise analysis on top of a {single|double}tone HB.

The simulation creates a series of directories under the psf database:

hb_td

hb_fd

hb_fi

hbnoise_xf

hbnoise

...

I am interested in the results contained in *hbnoise_xf*, as I am assuming that this directory contains the results, frequency by frequency, of the transfer functions from different points/devices in the netlist to the designated output.

Strangely enough, while the other mentioned directories contain results for each and every node in the netlist (I did a "save all" just to see whether this was the issue), the hbnoise_xf directory contains what seems to me to be a /random/ sample of the instances and devices contained in the top level.

There is only a few nodes in this directory. And of course, none of the ones I am interested in :)

I would like to understand why this happens and how can I influence the results reported in this directory.

Thank you in advance,

Michele

    ...On a second note, it looks like the hbnoise_xf is more concerned with voltage sources present in the schematic, so it is probably not what I am looking for. I think I have found what I was looking for, i.e. "Noise Separation". This creates the kind of results I need.
