.VehicleInterfaces.UsersGuide.ReleaseNotes.Version_2_0_0.ReintroduceExpandableConnectors

Information

As documented in the User's Guide, control signal buses are widely used within the library to easily exchange signals between vehicle's subsystems. In the previous versions of the VehicleInterfaces, the buses from packages <subsystem>.Interfaces were directly instantiated in the subsystem models, with the prefix "replaceable". This possibly led to some troubles especially when redeclaring a subsystem within a vehicle architecture, since the compatibility of the corresponding buses had to be granted.

In version 2.0.0 of the VehicleInterfaces, the original idea described in the User's Guide is introduced again. Consequently, only the buses from VehicleInterfaces.Interfaces are instantiated in the subsystem models and base classes. The prefix "replaceable" is omited. The bus signals are defined in buses located in <subsystem>.Internal packages, but those particular buses are only intended to enable a buildup of signal connection dialog (i.e. the GUI) when connecting a signal. Those particular buses shall not be used in models.

The buses formerly placed in packages <subsystem>.Interfaces are all marked obsolete and they were moved into a separate library ObsoleteVehicleInterfaces2. In user models, these obsolete connectors shall by replaced by buses from VehicleInterfaces.Interfaces. For example, a previous instantiation of engine bus such as

replaceable VehicleInterfaces.Engines.Interfaces.StandardBus engineBus
  constrainedby VehicleInterfaces.Interfaces.EngineBus
  annotation(...);

shall be replaced by

VehicleInterfaces.Interfaces.EngineBus engineBus
  annotation(...);
