Calculate Feature Instance

The primary function of this node is to select a subset of Test Devices for computing and debugging the Feature Instance. This process is based on the Eigen settings configured in earlier steps. By choosing specific Test Devices, users can focus on testing and refining the Feature Instance, ensuring it operates correctly before applying it more broadly across the network. The system will calculate Feature Instances by:


To calculate the Feature Instance, follow these steps:

  1. Set Minimal Device Count of One Feature Instance (Optional): This setting determines the minimum number of devices required to generate each feature instance.
    • The default value is 1, meaning that the feature instance will be created only when it contains one or more device. If the number of devices is less than or equal to the minimum device count, the feature instance will not be generated.
    • The valid input range is 1 to 1000, and this field cannot be left empty.
  2. Select Test Device: By default, this option is set to All Devices in Scope, including all devices specified in the Target Device setting of the This Feature step. You can modify this selection as needed based on your requirements.
    Information Note: The drop-down menu also includes an option New Test Device Set. You can select an existing Test Device Set from the menu. By default, no sets will be available, you have to create a New Test Device Set tailored to the current feature's characteristics. 
  3. By default, the system uses Live Data as the data source. To modify the data source, click the Settings icon and change the Data Source as needed.
  4. Click Run to initiate the calculation of the Feature instance.
    Information Note: Make sure to Save any changes before clicking Run, otherwise, a warning popup will appear.


    You can stop the execution process at any time. Only the results generated up to that point will be displayed.

Create New Test Device Set

If the existing Test Device Set is not available, follow these steps.
  1. Click New Test Device Set from the menu, it will open the Add New Test Device Set dialog.

  2. A new Test Device set can be created from two sources as follows:
    • From System Device: It opens the standard Select Device window. Select the required devices and click OK.
    • From Other Feature: Select the required devices and click OK.
  3. Enter the name for the new test device set and click OK to save and close the window.

View Feature Instance Result

After executing the logic of the Calculate Feature Instance node, the result table will populate the corresponding results. By default, the table includes three fixed columns:

  • Eigen Value: Each unique Eigen value generates a row. And, the devices with the same Eigen value are grouped into the same row.
  • Device: Displays the devices in this Eigen group.
  • Device Count: Shows the number of devices in the Eigen group.
    Information

    Note: The columns in the result table support sorting.


  • The View Feature Instance Result menu provide options to manage column visibility and export results.
    1. Show/Hide Columns: You can select or deselect columns to show or hide in the results table as needed (Default columns cannot be modified).
    2. Export All Results: Use this option to download the current results table as a .zip file. The file is saved with a default file name $featureName_Feature_Instance.zip.
