SysML Requirements Toolbox

When you are constructing SysML models, you can populate the Requirements diagrams using the icons on the SysML Requirements pages of the Diagram Toolbox.

Access

On the Diagram Toolbox, click on Search to display the 'Find Toolbox Item' dialog and specify 'SysML n.n Requirements' (whichever version you are using).

SysML Requirement Objects

Page	Item	See also
Requirement	Specifies the capabilities of the system, or the conditions that it should satisfy.
Test Case	Describes the verification of a Requirement through methods of inspection, analysis, demonstration or testing.

SysML Requirement Relationships

Item	Description
Containment	Graphically displays ownership of one element within a parent element.
Trace	Declares a trace relationship between a SysML Requirement and another SysML element.
Copy	Declares a copy of one SysML Requirement by another.
Derive	Derives a SysML Requirement from another.
Verify	Declares a verification of a SysML Requirement by another SysML element.
Refine	Declares a refinement of a SysML Requirement by another SysML element.
Satisfy	Declares that the SysML Requirement is satisfied by another SysML element.

SysML Requirement Extensions

Item	Description
Extended Requirement	Extends a SysML Requirement with additional Tag properties.
Functional Requirement	Declares a SysML Requirement that describes the operation, or behavior, that the system must perform.
Interface Requirement	Declares a SysML Requirement that describes how the system connects, or interfaces with, other systems.
Performance Requirement	Declares a SysML Requirement that describes how the system performs against defined capabilities or conditions.
Physical Requirement	Declares a SysML Requirement that describes the physical characteristics, or physical constraints, of the system.
Design Requirement	Declares a SysML Requirement that specifies a constraint on the implementation of the system.

Notes

SysML Requirements contain the Tagged Values 'Text' and 'ID', the values of which are not immediately visible in the 'Tags' tab of the Properties window; you can see the values more easily if you have the Summary window open (press Ctrl+6 or click on the 'Start > Desktop > Design > Summary' ribbon option) when you click on these elements
