How to save the results calculated in OCEAN?

This is my ocean script.

v1 = v("Vsampled")
fft1 = dB20(dft(v1,1m,19.874368,524288,"Cosine2",1,1)
plot(fft1)

How can I save fft1 in a file?

Later, from the file, I just want to plot the waveform in wavescan or
awd
without doing caculation again.

I don't want to do fft whenever I want the result since doing fft takes
some time.

Thanks in advance.

 

cyseok,

You can not save your secunday waveforms to file. That fancy
functionality was not implemented. There are ways to make ascii psf or
wsf from skill, but it is not so nice. There is no standard way of
saving a variable value (like fft1) to file, as with the 'pickle' module.

A few hints:
1- use a steady state analysis
2- use the ratiometric fourier component (in spectre)
3- use artWaveformToFile and artFileToWaveform

I do not recommend 3) unless there is a serious difficulty with the
former.
