getting the waves from a waveform window

[S. Badel]

i'd like to write a skill script that plots a waveform window
with a better look.

is there a way i can retrieve the waveforms (i.e. the individual points)
given a waveform window object?
couldn't find in the doc.

I'm not 100% sure if this is what you're asking for, but using the
calculator you may print any expression in a text file (2 columns or more if
you have more than one expression to plot).
You can do this by "printvs" button. I do not have a clue how this can be
done using skill, but I'm sure there is a way

Stephane:
I don't quite understand you question. Do you want to get the data
points in a text format and then plot with a different plotting tool?
If so, you can convert psf to ascii with:
psf -i tran.tran -o tran.txt

On top of the "psf" command and the ocnPrint/"print versus"
possibilities, you can use a signal-sink verilog-AMS device. I found
"voltmeter" in "ahdlLib" to do that.

You can also instruct spectre to write in nutmeg format, which is
recognised by many waveform tools already, and for which you'll easily
find a parser (in the spice source).

Could you tell more about this script ?
