A backlink is a navigation link in an external document that
allows you to navigate from a requirement to the linked item in MATLAB® or Simulink®. A backlink either has a corresponding direct link that points from the
item in MATLAB or Simulink to the external requirement, or matches a link that points from an item in
MATLAB or Simulink to an imported referenced requirement, which is an
slreq.Reference object that serves as a proxy object for the external
requirement. See Differences Between Importing and Direct Linking.
When you create a direct link from an item in MATLAB or Simulink to a requirement in an external document, you can insert a backlink. You cannot insert a backlink when you create a link from an item in MATLAB or Simulink to an imported referenced requirement but you can insert one after you create the link. You can also remove backlinks from an external document if the original link was removed.
You can insert backlinks in:
Microsoft® Word documents
Microsoft Excel® spreadsheets
IBM® Rational® DOORS® modules
IBM DOORS Next projects
When you create a link from an item in MATLAB or Simulink to an imported referenced requirement or a requirement in an external
Requirements™ creates a link as an
slreq.Link object. In some cases, you can choose to insert a backlink
in the external document when you create the direct link.
To manually insert or remove backlinks for your requirements:
Open the Requirements Editor. At the MATLAB command prompt, enter:
In the Requirements Editor, click Show Links to view the loaded link sets.
Select the link set that contains the links that you want to use to insert backlinks or to remove stale backlinks. Right-click the link set and select Update Backlinks.
A dialog box displays the number of links checked and the number of backlinks added and removed. Click OK.
The backlinks update process does not remove backlinks in IBM DOORS Next. Remove unwanted backlinks in DOORS Next in the DOORS Next interface.
