Viewing Requirements in the Navigator
Use the Navigator to see which objects have requirements associated with them.
Indication of Requirements
After adding a requirement to a node, the shading of the node's icon changes. In the Navigator, you can see which nodes have requirements associated with them by the shading of the node's icons.
The following example shows that nodes for the N block in the valve timing subsystem and the positive edge to dual edge conversion subsystem are shaded, indicating they have requirements associated with them. The nodes under the positive edge to dual edge conversion subsystem are lightly shaded, indicating they belong to a subsystem that has requirements associated with it.

Figure 1-8: Navigator Showing Simulink Nodes That Have Requirements
The shading of a node's icon indicates whether or not it has associated requirements, as shown in the following table.
