maestro: Can we create Output expressions, but hide them by default in results tables?

Often calculator expression become very long, and to better understand themand for debugging, you introduce intermediate outputs, like tevent=cross(...), then valAtEvent=value(x tevent), then Error=valAtEvent-expectedValfor50mA, then ErrorPercent=Error/RefValue*100

In my calibrated simulations I use this very very often, so my results table gets overcrowded quickly.

Can I force executing the intermediate expressions, but suppress  them in Results tables?

Even nicer, would be the ability to gray such intermediate values out, so that the eye can focus on the important outputs.

BTW, also nice would be the ability to use arrays, like becomes currently I need expressions like ErrorAt50mA, ErrorAt100mA, ErrorAt200mA.. to 1.5A.

    Dear StephanWeber,

    StephanWeber said:

    Maybe this is obvious to you, but it is not to me, but it seems as if the innate filtering of Assembler provides this feature. To use your example, it appears the final output expressions you wish to selectively view are somethng like:

    ErrorAt50mA, ErrorAt100mA, ErrorAt200mA....

    with intemediate values of:

    tevent=cross(...), then valAtEvent=value(x tevent), then Error=valAtEvent-expectedValfor50mA,

    By filtering the  "Output" column in the Results tab with the string "Error" and criteria "The Exact Phrase" (right click in filter box above "Output" column), only the rows whose output names contain "Error" will appear. You can save this filter for future use in subsequent tests. More complex logical criteria can also be applied.

    Figure 1 and Figure 2 show an example for an Assember session where I filter my output results to only include propagation time measurements that I define as starting with the string "tpd".

    This feature is explained in a lot more detail, and probably more clarity than I tried to do, in the Assembler User Guide at URL:

    I can't offer any advice on this - other than I would export the results and use Microsoft Excel's conditional expressions feature.

    I use Explorer/Assembler a lot, but I usually resort to ocean to provide any complex formatting or post-processing. As you mention Stephan, Calculator expressions can become very difficult to read, maintain, and pass on to someone else for their use. Implementing a desired output as an expression in a language such as ocean or Tcl/Tk in my opinion only, is far less error prone, far more readable by others, and easier to maintain and re-use.

    Thanks Shawn. I understand the filter usage, and use it already intensively, but e.g. the Yield results table allows no filtering. And I feel the filter settings are not very permanent.

    Do you have an example for using ocean or Tcl output expressions, to avoid having many expressions like ErrorAt50mA, ErrorAt100mA, ErrorAt200mA,...?

    Bye Stephan
