InstanceSpecification

SysMLv1: Cameo Simulation Toolkit: GOTCHA: In SysMLv1 it is "officially" recommended that an analysis context Block has a reference (only) to the subject of the analysis (but then you need to assign an instance as default value to make it run IN THE TOOL)

Webel: SysMLv1: TIP: Consider using high level "communication" Associations between Blocks in BDDs and corresponding object diagram BDDs WITHOUT any Ports, with Links typed by the Associations. Object diagrams are great for exploring Slot values, too.

Cameo Simulation Toolkit: You can assign the results of simulations calculations on instances to the default values of properties of the Classes/Blocks that type the instance.

UML/SysML: MagicDraw/Cameo: 19SP3: Instance Table Diagram sometimes does not display the values for nested value properties

UML/SysML: MagicDraw/Cameo: Instance Table Diagrams are one of the most powerful features of MagicDraw/Cameo! Learn to use them to progressively test, debug, and evolve your models as you work!

An InstanceSpecification is a model element that represents an instance in a modeled system.
