getData returns nil

Nicolas Callens

Dear all,

To get a wave object from my simulation results, I am trying to use the getData() command. However, I am having some issues with it. For example, getData("/OUT") returns nil in the CIW after I have simulated my testbench in ADE XL. However, when I am explicitly specifying the resultDir in getData() I am not getting this error (logically). I have used openResults() in order to use getData("/OUT") but without success. When can I use getData("/OUT")?

Kind regards, 

Nicolas

  • Hi Nicolas,

    For a start, you almost certainly need to specify ?result to tell it which analysis to get the result from (e.g. getData("/OUT" ?result 'tran)) - otherwise it doesn't know. In ADE XL you're running multiple simulations, and ADE will open the results for each individual simulation one at a time, but I think that only happens if you're plotting something (otherwise it doesn't need to do this) - and so which one you get will be whatever was opened last, which is somewhat arbitrary. You can certainly use getData in an output expression (you'll need to specify ?result though), but if you want to use getData arbitrarily in the CIW, you'll have to call openResults() or specify ?resultDir to explicitly state the directory.

    Regards,

    Andrew.

    Thanks for the clarification. Though, the manual gives an example where getData() is used without ?result and ?resultsDir. Is this an error?

    Nicolas,

    Probably not. You can omit the ?result argument if you call selectResult() beforehand to specify the current result to use. Obviously that’s not something you’d do as part of a single expression - that’s mostly for when you’re reading results in an OCEAN script. 

    Regards,

    Andrew
