Close the model.
Note: When you navigate to a DOORS requirement from outside the software, the
DOORS module opens in read-only mode. If you want to modify the DOORS module,
open the module using DOORS software.
Insert Navigation Objects to Multiple Simulink Objects
If you have several Simulink objects that correspond to one requirement, you can link
them all to that requirement with a single navigation object. This eliminates the need to
insert multiple navigation objects for a single requirement. The Simulink objects must be
available in the same model diagram or Stateflow chart.
The workflow for linking multiple Simulink objects to one DOORS requirement is as
follows:
1
Make sure that you have enabled Modify destination for bi-directional linking.
2
Select the DOORS requirement to link to.
3
Select the Simulink objects that need to link to that requirement.
4
Right-click one of the objects and select Requirements Traceability > Link to
Selection in DOORS.
A single navigation object is inserted at the selected requirement.
5
Double-click the navigation object in DOORS to highlight the Simulink objects that
are linked to that requirement.
