PSF Family vs Leaf waveforms

analogy
I have a parametric sweep with variable A = [a1 a2 a3 a4 a5] and after ADE-XL simulation, I can plot Vout as,
Vout
   ‘-Vout (A=a1)
   ‘-Vout (A=a2)
   ‘-Vout (A=a3)
   ‘-Vout (A=a4)
which is to say as family of waves (i.e. leaves).
But when I save these family of waves as PSF (using Export>PSF), and I load this PSF result in ViVA , I no longer have family of waves, I end up getting individual waves i.e. each leaf ungrouped and plotted separately :
Vout (A=a1)
Vout (A=a2)
Vout (A=a3)
Vout (A=a4)
This can be annoying if one is supposed to use calculator to perform additional processing post simulations.How do I group these individual waveforms (i.e. leaf) to a family of waves while exporting them as PSF ?

  • Sorry, you can't.

    Currently when you export from ViVA, it only saves a single database file (PSF, VCSV etc). It saves an associated logFile which simply refers to the single database file.

    In order to support family data, it would need to write multiple PSF files and then write a logFile which acted as the index for each sweep member. That  would require an enhancement - for which you'd need to contact customer support (from a quick search I didn't find any existing request for this, although it seems reasonable to me).

    Why are you exporting PSF rather than keeping the original waveform databases?

  • Let's say you want to share a single plot (expression output) to someone else.For this, first I will plot this expression , next I will export expression wave as a standalone psf data and finally I will reopen this exported psf data, edit window properties like axes range, legend and any other comments using graph labels and save this as Window.

    The other person can read this expression output using ViVA Waveform on his/her account by loading the Window (provided he/she has both - exported PSF data and Window .grf file).Sounds confusing , right ?

    Well, the reason for this long procedure is that when using parametric sweeps with more than one variable to be swept, exporting waves as .csv and reading them back in Matlab (even with toolbox) is a nightmare.

  • Speaking of PSF :

    Andrew,

    Let's say after ADE-XL simulation run Interactive.0 you want to send simulation data for someone else to read on a different host.Can you simply send the folder Interactive.0 in the directory simulation/...../adexl/results/data/ and use ViVA (Open Results) on a different host to  read psf inside Interative.0 folder ?

    I tried this and nothing happened.

    P.S. I am aware of ocnPrint() but I was wondering if psf data from ADE-XL run directory can be read standalone on ViVA.

  • Ideally the data would be accessible over the network, but even if not, you should be able to just point ViVA at the results/data/Interactive.N/psf/testName/psf dir and it should work. I can only imagine that if it doesn't work, it's some permission problem - because it really should (it's no different to using the results browser in ADE XL). I just did this myself (although I was sure it would work).

    BTW, no need to export to CSV to read into Matlab; you can use the spectre toolbox for Matlab (if running on Linux) and directly read the PSF data into Matlab.

    Regards,

    Andrew.

  • About spectre toolbox : What if MATLAB isn't installed on host machine ?

  • Not sure why that would matter - this should work too. Note that you can't use Matlab on Windows though because there's no spectre toolbox support on Windows.

  • I see.

    By the way, I have a very peculiar problem as far as ViVA is concerned.When I try to open dialog to select results via File>Open Results  or any other method, ViVA gets stuck and frozen.

    Log file for brevity.

  • I've not seen this. If this is before you've selected a file to load, then it may be a file system or network problem causing a hang (e.g. a stale mount).

    I would suggest contacting customer support - there's probably little we can do about it in the forums without seeing it.

    Regards,

    Andrew.
