View trace links

A trace link is a directional relationship between any two objects, including requirements and blocks in functional models, system models, or physical models.

You use trace links for allocating requirements to elements in downstream or upstream structures, such as:

• Other requirements in the same structure or in different requirement views.
• Functional model blocks, systems model blocks, and physical models.

View trace links associated with an object

1. Search for the requirement (or other object) or navigate to it in your Home folder. In the content list, objects with trace links appear with the trace link (chain) symbol on the thumbnail image.
2. Perform any of the following:
   • Hover over the trace link icon to see the number of objects that are linked.
   • Click the Trace Link tab, which lists all complying and defining objects associated with the selected object, regardless of where they exist. It also includes the relation type for each object.
   • Click the requirement to open the requirement in the Documentation tab.

View trace links associated with an object in a working context

A working context provides a way to put your work aside for a while, then pick up where you left off when you return. Your working context can be retrieved from any device.

1. Search for the structure that contains the object or navigate to it in your Home folder.
2. With the context open in the Navigate tab, click the Architecture tab. The model shows a visual representation of trace links between objects in the structure.
3. Do one of the following:
   • Use the Relations panel: Click to open the Relations panel. The Trace Links tab lists the model objects that have incoming and outgoing trace links. You can collapse and expand the Incoming and Outgoing lists. The thumbnail next to each object indicates whether its trace link is displayed in the model; click the thumbnail to toggle it. The Relations panel shows only the trace links present in the context.
   • Use the Relations Controls tool: Click Relation Controls. The Legend panel displays the relation types for the objects currently displayed in the model. Trace links are tallied next to Traceability. Click the colored box next to Traceability to switch the display of all trace links on and off in the model.
