Accessing ADEXL outputs from Ocean

pkerichang

Hello,

So I ran a parametric sweep with ADEXL and sets a history tag name.  Then, later in Ocean I use axlReadHistoryResDB() to load the simulation results from that history, and use the ResDB data structure and openResults() to load simulation results from a particular parametric sweep point.  However, I can't figure out how to access the outputs defined by the ADEXL in the GUI.  It exists as an output in the ResDB data structure, but if the output is a signal instead of a scalar there is no data associated with it.  How can I access the output in ocean?  Can I at least get the ocean expression associated with the output and evaluate it to recover the data?

    Eric,

    This is much harder than it should be (I think an enhancement in this area would be worthwhile). The RDB doesn't contain the waveform data, so the value slot for something with a waveform will just say "wave".

    You'd need to do something like:

    axlSess=axlGetWindowSession()
    sevSess=axlGetToolSession(axlSess "testName") ; possibly need the ?history here too
    asiSess=sevEnvironment(sevSess)
    ; find the output structure you want
    output=car(exists(output asiGetOutputList(asiSess) output~>name=="OUTNAME"))

    Then output~>expression will contain the expression you want.

    Then you could use (say) the rdb->test("testName" "C0_0" 1) function to get the info about a particular corner and point number, and from this you have ~>resultsDir - so I can do:

    result=rdb~>test("testName" "C0_0" 1)
    openResults(result~>resultsDir)
    waveform=eval(output~>expression)
    plot(waveform)

    The new Maestro API for ADE Explorer and Assembler also doesn't quite handle this - the maeGetOutputValue() function also returns "wave" for something that is a waveform.

    Regards,

    Andrew.
