SysML Requirements

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

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

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.
