Requirements Management Interface

Viewing Requirements in the Navigator

Use the Navigator to see which objects have requirements associated with them.

Indication of Requirements

In the Navigator, you can see which nodes have requirements associated with them by the shading of the node's icons.

1. Select Synchronize from the File menu in the Navigator so that the links you just made in DOORS are reflected in the Navigator.

This 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 DOORS requirements associated with them. The nodes in the positive edge to dual edge conversion subsystem are lightly shaded, indicating they belong to a subsystem that has requirements associated with it.

The shading of a node's icon indicates whether or not it has associated requirements, as shown in the following table.

Table 2-1: Node Icons in Navigator and What They Represent  

Node	Shading	What It Represents
	Not shaded	Simulink subsystem with no requirements
	Shaded	Simulink subsystem that has requirements
	Lightly shaded	Simulink subsystem belonging to a subsystem that has requirements; subsystem itself has no requirements
	Not shaded	Simulink block with no requirements
	Shaded	Simulink block that has requirements
	Lightly shaded	Simulink block belonging to a subsystem that has requirements; block itself has no requirements
	Not shaded	Stateflow chart with no requirements
	Shaded	Stateflow chart that has requirements
	Lightly shaded	Stateflow chart belonging to a subsystem that has requirements; chart itself has no requirements
	Not shaded	Stateflow state with no requirements
	Shaded (with yellow)	Stateflow state that has requirements
	Lightly shaded	Stateflow state belonging to a superstate, chart, or subsystem that has requirements; state itself does has no requirements
	Not shaded	Stateflow transition with no requirements
	Shaded (with blue)	Stateflow transition that has requirements
	Lightly shaded	Stateflow transition belonging to a superstate, chart, or subsystem that has requirements; transition itself has no requirements
	Not shaded	MATLAB M-file with no requirements
	Shaded	MATLAB M-file that has requirements

2. Select a node that has requirements associated with it. If the node contains other nodes, first click next to the node to expand it, and then select the specific node you want.

The surrogate exported module name (Document) and object identifier (ID) appear in the right pane of the Navigator.
