Searching/Deleting Unused Elements

You can delete elements (scalar or complex) not used in the conditional table.

1. In the "Extras" menu, select Show Unused Elements.

   The "Search Results" view opens. It shows all elements listed in the "Outline" tab, but not used in the conditional table.

   A scalar element in the "Outline" tab is unused in the conditional table (i.e. does not appear in the generated ESDL code) if one of the following conditions is fulfilled.

   Neither Get port nor Set port of the element is activated in the element's properties editor. AND The element is not assigned to a column AND does not appear in the specification of a condition or instruction (log in the screenshot) OR appears in a specification of an instruction, but all conditions in that row (except "default") are set to * (log_2 in the screenshot). OR The element is assigned to one or two columns AND all cells of the assigned column(s) are set to * AND the element does not appear in the specification of a condition or instruction (limitInt in the screenshot) OR the element appears in the specification of a non-default instruction, but all conditions in that row are set to * (cont in the screenshot) OR The element is assigned to an instruction column AND one or more instruction cells are != *, but all respective condition cells are * (log_1 in the screenshot)

   An included class is unused in the conditional table if the following conditions are fulfilled.

   • The included class is not used in an instruction.

     AND

   • Neither Get port nor Set port of the included class is activated in the element's properties editor.

     AND

   • The included class does not contain (directly or indirectly) an exported element that is used.

     AND – if applicable –

   • The included C code class contains no target/arithmetic/implementation combination with an external header that is used globally (activated option Use header global; see Adding a Header File to the Source Module).

2. In the "Elements" tab of the "Search Results" view, select one, several, or all (<Ctrl> + <a>) elements.

3. Do one of the following:

   • Open the context menu and select Delete.
   • Press the Del key.

   The selected unused elements are deleted.
