Get the waveform information from output expressions in Maestro

mapReduce

I am trying to import the output expressions I created in Maestro into a Skill script for further processing. I intend to import the waveform for the output expression into Skill and do the processing on the data. I got the output instance for the expression using this code:

session = axlGetWindowSession()
x_mainSDB = axlGetMainSetupDB(session)
x_historyHandle = axlGetRunData(session 0)
t_historyName = axlGetHistoryName(x_historyHandle)
x_history = axlGetHistoryEntry(x_mainSDB t_historyName)
rdbPath = axlGetHistoryResults(x_history)
rdb = axlReadResDB(rdbPath)

o_exprHandle = rdb->output("o_expr" "sweep_test" "nominal" 1)

In this code, o_expr is the expression I am trying to import and sweep_test is the name of the test. But I do not understand how can I get the waveform object from this output handle.

  • You can't - the RDB doesn't contain the waveform data, just scalar data. The waveform has to be constructed from the underlying data.

    I think (if memory serves me correctly) that the calcVal function is potentially the easiest way of getting the data, but you probably would be wise to contact customer support because I think this ought to be easier to access than it is in practice.

    Regards,

    Andrew.
