Tutorial and Examples

During runtime you can change the dynamic parameters. A common use case is that you have many operators in a design and you need to change the same parameters e.g. the image dimensions for many different operators in the design.

In the library Parameters, you can access different operators in a design by controlling only one parameter and/or to display the parameter on a specific hierarchy level for easier parameter configuration during runtime. Whether the library Parameters is available for you depends on the license you have purchased. For questions regarding your license, contact the Basler Sales Department. The example design Sobel_Filter.va (see Figure 172, 'Example Design Implementation Sobel_Filter.va') uses translate and reference parameters to easily access image width and height, the image source selector, the threshold value and the scale factor on the hierarchy level Parameters. For this, create an empty HierarchicalBox, name it Parameters and set the DisplayHierarchy parameter of the corresponding translate and reference parameters to Parameters. You find a detailed documentation of the Parameters library in the corresponding documentation, see Library Parameters.
