Some capabilities available for UML classes, such as more specialized forms of associations, have been excluded from SysML blocks to simplify the language. Full quote SysML blocks always include an ability to define internal connectors, regardless of whether this capability is needed for a particular block. Next snippet SysML Blocks also extend the capabilities of UML classes and connectors with reusable forms of constraints, multi-level nesting of connector ends, participant properties for composite association classes, and connector properties. Related snippets Blocks are modular units of system description. Blocks provide a general-purpose capability to model systems as trees of modular components. The specific kinds of components, the kinds of connections between them, and the way these elements combine to define the total system can all be selected according to the goals of a particular system model.
