Something is missing in this command

Hello All,

I'm using the function awvPlotSignals the syntaxis is awvPlotSignals(signal  ?plotStyle ?graphType) , but I can't understand how to set what type of signal to plot ( terminal or net ) by default seem to be net and when I try to plot terminal appears error for missing waveform.

Does anyone know how to define the signal type?

Regards,

Nikolay

  • Dear Andrew,

    After 1 year... I'd be interested in representing the stability of my circuit in a polar chart.
    I'm running a simple STB analysis but somehow I can't get the following working:

    awvPlotSignals(getData("/loopGain" ?result "stb") ?graphType "polar")
    "(\"foreach\" 0 t nil (\"*Error* foreach: second argument must be a list\" srrWave:0x288c70f0))"

    Expecting a list, not taking a Waveform.
    I've then checked the Help and tried to adapt the syntax from given

    awvPlotSignals((("./ampsim.raw" (("ac-ac" ("net10"))))) ... )

    to a 'wonky'

    awvPlotSignals((("openResults()" (("stb" ("/loopGain"))))) ?graphType "polar")
    "(\"eval\" 0 t nil (\"*Error* eval: not a function\" (\"openResults()\" ((\"stb\" (\"/loopGain\"))))))"

    I don't get the syntax needed here...
    Target would be to get a proper visual of Gain and Phase margins (which tend to be sometimes masked in the Bode representation) - getData("phaseMargin" ?result "stb_margin") and gainMargin are nice but I wouldn't trust them 100%...

    Thanks in advance for your possible feedback,
    Kind regards,
