| AutosarDataPrototype implementation | Definitions and declarations for non automatic1 memory objects which are allocated by the RTE and implementing AutosarDataPrototypes or their belonging status handling. 1.declaration with no static or external specifier defines an automatic variable |
| BswSchedulableEntity activation | The activation of a BswSchedulableEntity is defined as the activation of the task/ISR2 that contains the BswSchedulableEntity and eventually includes setting a flag that tells the glue code in the task/ISR2 which BswSchedulableEntity is to be executed. |

| ’C’ typed PerInstanceMemory | ’C’ typed PerInstanceMemory is defined with the class PerInstanceMemory. The type of the memory is defined with a ’C’ typedef in the attribute typeDefinition. |
| client | A client is defined as one ClientServerOperation in one RPortPrototype of one Software Component instance. For the definition of the client neither the number of ServerCallPoints nor RunnableEntity accesses to the ServerCallPoint are relevant. A Software Component instance can appear as several clients to the same server if it defines ServerCallPoints for several PortPrototypes of the same PortInterface’s ClientServerOperation. |
| CodeGenerationTime variability | Variability defined with an VariationPoint or AttributeValueVariationPoint with latest bindingTime CodeGenerationTime. |
| coherent implicit data access | An implicit read access or an implicit write access which belongs to coherency group. Therefore it is referenced by a RteVariableReadAccessRef or RteVariableWriteAccessRef belonging to a RteImplicitCommunication container which RteCoherentAccess parameter is set to true. |
| coherent implicit read access | An implicit read access which belongs to coherency group. Therefore it is referenced by a RteVariableReadAccessRef belonging to a RteImplicitCommunication container which RteCoherentAccess parameter is set to true. |
| coherent implicit write access | An implicit write access which belongs to coherency group. Therefore it is referenced by a RteVariableReadAccessRef or RteVariableWriteAccessRef belonging to a RteImplicitCommunication container which RteCoherentAccess parameter is set to true. |
| common mode machine instance | A ‘common mode machine instance’ is a special ‘mode machine instance’ shared by BSW Modules and SW-Cs: The RTE Generator creates only one mode machine instance if a ModeDeclarationGroupPrototype instantiated in a port of a software-component is synchronized (synchronizedModeGroup of a SwcBswMapping) with a providedModeGroup ModeDeclarationGroupPrototype of a Basic Software Module instance. The related mode machine instance is called common mode machine instance. |
| Communication Graph | The sum of all AbstractAccessPoints to elements of PortInterfaces instantiated in PortPrototypes which are connected to each other, or the sum of all accesses from BswModuleEntitys to interface elements in a BswModuleDescriptions connected to each other. Data Communication Graph The sum of all VariableAccesses to VariableDataPrototypes instantiated in PortPrototypes which are connected to each other, or the sum of all VariableAccesses to VariableDataPrototypes in the InternalBehavior, or the sum of all BswVariableAccesses to VariableDataPrototypes in BswModuleDescriptions connected to each other. |

| core local mode user group | In the case that mode users belong to different partitions which in turn are scheduled on different micro controller cores the overall mode machine instance needs to be distributed cross core. Thereby some restrictions are only applicable between the mode users executed on the same micro controller core. All mode users of the same mode manager which belong to EcucPartition which in turn belong to OsApplications referring to the same EcucCoreDefinition are belonging to the same core local mode user group. |
| data semantic | When data is distributed, the last received value is of interest (last-is-best semantics). Therefore the software implementation policy, stated in the swImplPolicy attribute of the SwDataDefProps, shouldn’t be ’queued’. |
| event semantic | When events are distributed the whole history of received events is of interest, hence they must be queued on receiver side. Therefore the software implementation policy, stated in the swImplPolicy attribute of the SwDataDefProps, will have the value ’queued’(corresponding to event distribution with a queue). |
| execution-instance | An execution-instance of an ExecutableEntity is one instance or call context of an ExecutableEntity with respect to concurrent execution, see section 4.2.3. |

See also section 4.4.1. |
| mode machine instance | The instances of mode machines or ModeDeclarationGroups are defined by the ModeDeclarationGroupPrototypes of the mode managers.

For all mode users of the same mode manager’s ModeDeclarationGroupPrototype, RTE and Basic Software Scheduler uses the same mode machine instance. See also section 4.4.2. |

| mode switch port | The port for receiving (or sending) a mode switch notification. For this purpose, a mode switch port is typed by a ModeSwitchInterface. |
| mode user | An AUTOSAR SW-C or AUTOSAR Basic Software Module that depends on modes is called a mode user. The dependency can occur through a SwcModeSwitchEvent/BswModeSwitchEvent, a ModeAccessPoint for a provided/required mode switch port, or a accessedModeGroup for a providedModeGroup/requiredModeGroup ModeDeclarationGroupPrototype. See also section 4.4.1. |
| NvBlockSwComponent | NvBlockSwComponent is a SwComponentPrototype typed an NvBlockSwComponentType. |
| on-entry ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is triggered by a SwcModeSwitchEvent respectively a BswModeSwitchEvent with ModeActivationKind ‘entry’ is triggered on entering the mode. It is called on-entry ExecutableEntity. See also section 4.4.1. |
| on-exit ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is triggered by a SwcModeSwitchEvent respectively a BswModeSwitchEvent with ModeActivationKind ‘exit’ is triggered on exiting the mode. It is called on-exit ExecutableEntity. See also section 4.4.1. |
| on-transition ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is triggered by a SwcModeSwitchEvent respectively a BswModeSwitchEvent with ModeActivationKind ‘transition’ is triggered on a transition between the two specified modes.

| trigger source | A trigger source administrate the particular Trigger and informs the RTE or Basic Software Scheduler if the Trigger is raised. A trigger source has dedicated provide trigger port(s) or / and releasedTrigger Trigger(s) to communicate to the trigger sink(s). |
| triggered BswSchedulableEntity | A BswSchedulableEntity that is triggered at least by one BswExternalTriggerOccurredEvent or BswInternalTriggerOccurredEvent. In particular cases, the Trigger Event Communication or the Inter Basic Software Schedulable Entity Triggering is implemented by Basic Software Scheduler as a direct or trusted function call of the triggered ExecutableEntity by the triggering ExecutableEntity. |
