Interfacing Spectre Output to MATLAB

RFQuery

 Dear All,

Can anybody tell me how to interface Spectre (ADE) output (like waveform) to MATLAB for further processing

  • The <MMSIMinstDir>/tools/spectre/examples/SpectreRF_workshop/MatlabAN.pdf is less RF-centric (the toolbox was developed by the SpectreRF team, hence the RF focus of many of the examples).

    To access AC results, you can do this:

    % access the info about all the signals in the results
    signals=cds_srr(resdir,'ac-ac')
    % show the Voltage signal names
    signals.V
    % show the Current signal names
    signals.I
    % get the V4:p signal
    V4_p=cds_srr(resdir,'ac-ac','V4:p')
    % look at the details
    V4_p.I
    V4_p.freq
    % plot the signal
    cds_plotsig(V4_p,'','freq','db20')

    for example.

    I suspect that when you did the signals=cds_srr(...) it did list all the signals, but note that you probably got a horizontal scrollbar and may not have seen then all. However, looking at signals.I and signals.V should show everything. You certainly should see the same signals that you'd see in the results browser in ADE - and if they're missing there it would be because you didn't save the signals from the simulator.

    Note that you could also plot the waveform directly yourself using:

    plot(V4_p.freq,abs(V4_p.I))

    this is the equivalent of using 'mag' instead of 'db20' in the cds_plotsig, except it doesn't label the axes and so on.

    Hope that helps!

    Regards,

    Andrew.
