Click the Coverage Analysis View tab in the main window to display the Coverage Analysis view, which you can use to select elements from a project document and display requirement coverage one level upstream and one level downstream from the selected document.

Note Note  Refer to Chapter 3, Analyzing Requirements, of the Getting Started with NI Requirements Gateway manual for a tutorial on using the Coverage Analysis view.

Columns

The Coverage Analysis view contains the following columns:

  • Upstream Coverage Information—For an element of a document you select in the Selection column, the Upstream Coverage Information column displays the immediate upstream elements the selected element covers. Double-click a document or an element in the Upstream Coverage Information column to select the document or element in the Selection column.
  • Selection—Displays the content of all the documents in the project. When you select an element of a document in the Selection column, the information in the Upstream Coverage Information and Downstream Coverage Information columns changes depending on the element you select.

    Rearrange the order of documents in the Selection column by selecting a document and dragging it up or down to a new position. Rearranging the order of documents in the Analysis views does not change the covering relationship of the documents. You must save the project before attempting to edit the project.

    If you make several consecutive selections, use the Back and Forward buttons on the toolbar to return to the previous selection.

    The Selection column contains the following nodes:
    • Rule check—Displays a summary of any rule violations for the project and lists the elements that violate a rule. Double-click a listed element to select the element in the Selection column.
    • <Documents>—Lists all the documents in the project. Each document displays the document name, type, and type icon and includes a tree view of all the traceability information that Requirements Gateway captures from the document intermediate file.

      Expand each element in the Selection column to view the requirements or attributes that each element contains. Press <Shift> while expanding an element to expand all child elements. Each element in the tree view has an associated icon, as shown in the following table.

      Icon Description
      Section

      Not all types use the default icons. Some types, such as TestStand and LabVIEW, have many categories of elements that use other icons. When you create a custom type, you can also select custom icons for each element.
  • Downstream Coverage Information—For an element of a document you select in the Selection column, the Downstream Coverage Information column displays the immediate downstream elements that cover the selected element. Double-click a document or an element in the Downstream Coverage Information column to select the document or element in the Selection column.

Hover the cursor over an element in the Selection column to view additional information about the element in the tooltip. For example, if you hover over a requirement that uses a Functional Requirement type, the tooltip shows the name of the requirement and displays Type: Functional Requirement beneath the name.

With an element selected in the Selection column, hover the cursor over an element in the Upstream Coverage Information and Downstream Coverage Information columns. The tooltip displays Reference Type: Name to indicate the reference type that links the upstream or downstream element with the element selected in the Selection column.

Tabs

The Coverage Analysis view also contains the following tabs that display details about the element you select in the Selection column.

  • Texts and Reference Attributes—Displays the text for the element you select and any attributes for references that link the element you select to a corresponding element in the Upstream Coverage Information or Downstream Coverage Information column.
  • Attributes—Displays the attributes for the element you select.
  • Messages—Displays helpful information, including rule violation details, for the element you select.
