OCEAN getData behavior

SharksFan

 Hi,

I have a list of signals and corresponding strip numbers that I want to plot them on in a form like:

 my_stripAssignment = list( '(v("/enable")       1)

                                              '(v("/disable")       2) )

I have a foreach loop that grabs the signals and their strip number assignment one-by-one:

foreach( signal_name my_stripAssignment

 plot( getData(car(signal_name)) ?strip cadr(signal_name) ) )

I noticed that if I query the signal_name during the loop that it no longer just returns the assigned value out of the list, but instead also has the resultsDir and result data along with it.  In other words, I expected signal_name to return v("/enable") , but instead it returns v("/enable" ?resultsDir "/home/user/CDS/OCEAN/test/psf" ?result "tran").

So it seems this change happens after I use the getData command.  Am I doing something wrong?  Is there a better approach?  Or is getData messing me up?

    Well, I'm very surprised, because that would mean that your code was doing:

    getData('v("/enable"))

    and that should not work (and did not work when I tried it). Still, I'm happy to be wrong, but I certainly would not want  your code to depend upon this because it is not supposed to work, and is unlikely to be future-proof. It should be (of course):

    getData("/enable")

    Note that there is no bug here. When you call getData without the ?result or ?resultsDir argument, it picks those arguments up from the last openResults() call (or the results from the last completed simulation if you ran a simulation in the same session), and the ?result arg comes from your last call to selectResult(). The waveform object that it creates has the expression property set (on the y-vector) to the be the quoted function that created it. You can always override this by setting drGetWaveformYVec(waveObj)->expression=... 

    Regards,

    Andrew.
