MagicDraw/Cameo 19SP3: Does not yet handle Property-wise Type compatibility validation of FlowProperty contracts (it only handles them at the level of entire Block types). Webel asserts the spec is inconsistent w.r.t. ProxyPort connection compatibility.

Inversely, the InternalCombustionEngine can read the isControlOn property of the PowerControlUnit across the connector to determine if the unit is still operating, and possibly shut down if it is not. Source OMG Systems Modeling Language (SysML) 1.6
By invoking these operations, the PowerControlUnit can set the throttle and mixture of the InternalCombustionEngine. The PowerControlUnit can also read properties of the InternalCombustionEngine across the connector to find out the rpm, temperature, ... Source OMG Systems Modeling Language (SysML) 1.6
Since the ecu:PowerControlUnit part and ice:InternalCombustionEngine part are connected via these ports, the ecu:PowerControlUnit part may invoke setThrottle and setMixture on the ice:InternalCombustionEngine part via its ice port, across the connector...

This means the provided features of ICE are provided by the ctrl port of InternalCombustionEngine, and required by the ice port of PowerControlUnit, while the required features of ICE are required by the ctrl port of InternalCombustionEngine, and provided Source OMG Systems Modeling Language (SysML) 1.6
For example, the ICE block specifies the provided operations setMixture and setThrottle, the provided properties RPM, temperature, and isKnocking, and required property isControlOn, as shown in Figure D.20. This block types the ctrl port of ... Source OMG Systems Modeling Language (SysML) 1.6
The ecu:PowerControlUnit part has three ports with required and provided features, each connected to a port of another part. Each of the ports in this example is typed by a block specifying provided and required features available via connectors ... Source OMG Systems Modeling Language (SysML) 1.6
MagicDraw/Cameo 19SP3: Does not yet handle Feature-wise validation of provided/required DirectedFeature contracts (it only handles them at the level of entire Block types). Webel asserts the spec is inconsistent w.r.t. ProxyPort connection compatibility.
SysMLv1.6 Provided/required DirectedFeature contracts for ProxyPorts SHOULD be satisfiable Feature-wise (including as subsets of Features) not necessarily just at the level of entire Blocks (types)! [See also the SysMLv1.7 spec changes.] ARCHIVAL (2022): This content is now considered historical only!
MD SysML and Cameo 19SP3 can't yet validate provided/required Feature subsets (such as Features of one Block against Features of multiple Ports)
