Software Function Navigation

Seamless Function Wallpaper

EHANDBOOK-NAVIGATOR supports to navigate from Function Overview to Interactive models in a single window through Seamless function wallpaper.

It helps to make the connections for Function Overviews and Function Specifications (ASCET/Simulink) or Function Implementation (C-Code) continuously which means that you can navigate in the function wallpaper by means of connections from Function Overviews to Function Specifications (ASCET/Simulink)/Function Implementation (C-Code) or vice-versa in a single window.

The Seamless function wallpaper operation can be done by expanding the seamless_function_wallpaper_icon icon which is available at the top left corner of every Function Overview block or the Function Specifications (ASCET/Simulink) or Function Implementation (C-Code) block. It is also possible to navigate in a seamless function wallpaper via click navigation, i.e. Navigate in and Navigate out.

  1. Function Overview entry in the TOC

  2. Function Implementation (C-Code) entry in the TOC

  3. Function Specifications (ASCET/Simulink) entry in the TOC

  4. Function Overview diagram in the Model Viewer

  5. Expand icon

  6. Function Implementation (C-Code) diagram in the Model Viewer

  7. Function Specifications (ASCET/Simulink) diagram in the Model Viewer

In general, it helps you to:

  • Navigate in/out to switch between Function Overviews and Function Specifications (ASCET models/Simulink models)/Function Implementation (CCode based models) diagrams.

  • Expand/collapse Function Overviews and integrate contained Function Specifications/Function Implementation diagrams. It provides virtual connections between Function Overviews and Function Specifications/ Function Implementation blocks.

  • Enables the signal flow highlighting.

Seamless Function Wallpaper Operation

To operate the Seamless function wallpaper:

  • Click on Function Overviews or Function Specifications (ASCET/Simulink) or Function Implementation (C-Code) entry in the TOC in the Document Explorer.
    The selected diagram is displayed in the Model Viewer.

  • Click seamless_function_wallpaper_icon icon to expand the corresponding block.
    If a Function Block is expanded, you can view all the interactive models of that Function.
    If a Function Specification (ASCET/Simulink) Block or Function Implementation (C-Code) Block is expanded, you can view all the ports and connections which are connected to that model.

You can view the virtual connections which are connected in the model in Auto Layout mode only. The connections are not shown in the Default Layout mode.

Viewing the Function Overview Diagram Through an Interactive Model

Seamless function operator helps to view the Function Overview diagram, Interactive models, and connections in a single window. In the same way, you can also view the Function Overview diagram from the Interactive models.Navigate out feature helps to view the Function Overview diagram from the Interactive models in the Model Viewer.

To view the Function Overview diagram:

  • Click Navigator_out_icon in the toolbar.

  • Right-click on an interactive model.
    A context menu is displayed.

  • Click Navigator_out_icon_menu
    A Function Overview diagram is displayed.

Signal Flow Highlighting or Hiding in the Seamless Function Wallpaper

Highlight connected elements/Hide connected elements of an input/output of a block in the Seamless function wallpaper helps you to view the highlighted/ hidden elements or ports of multiple blocks in a single window. When you click Highlight connected elements/Hide connected elements of a port of a function block, the signal flow highlighting/hiding crosses the interface of the function block and it ceases at the simple element of the interactive block encountered in that path. It also highlights/hides the ports, if they are impacted.
