138 Specification of Execution Management
2 Acronyms and abbreviations
All technical terms used throughout this document – except the ones listed here – can be found in the official [3] AUTOSAR Glossary or [4] TPS Manifest Specification.
Certain requirements necessitate the specification of mandatory whitespace. This is indicated by ‘ ’ in the requirement text.
Term | Description |
---|---|
Application | An implementation that resolves a set of coherent functional re- quirements and is the result of functional development. An Ap- plication is the unit of delivery for Machine specific configu- ration and integration. |
Executable | Part of an Application. It consists of executable code (with exactly one entry point) created at integation time that can be deployed and installed on a Machine. An Application may consist of one or more Executables, each of which can be de- ployed to different Machines. |
Process | A Process is an instance of an Executable to be executed on a Machine and has a 1:1 association with the ARXML/Meta- Model element with the same name. This document also uses the term process (without a capital "P") to refer to the OS con- cept of a running process. |
Attention: Process != process. Hence each Process has at some time a related process but a process may not always have a related Process. | |
Reporting Process | A type of Process with an associated Executable where re- portingBehavior is omitted ([TPS_MANI_01279]) or set to reportsExecutionState. Such a Process is expected to report its Execution State to Execution Management. |
Non-reporting Process | A type of Process with an associated Executable where re- portingBehavior set to doesNotReportExecutionState. Such a Process is not expected to report its Execution State to Execution Management. |
Self-terminating Process | A type of Process that self initiate termination procedure, please note that for a standard Process this procedure is initiated by Execution Management. |
Execution Dependency | Dependencies between Executable instances can be config- ured to define a sequence for starting and terminating them. |
Execution Management | The element of the AUTOSAR Adaptive Platform responsi- blefortheorderedstartupandshutdownoftheAUTOSAR Adap- tive Platform and the Applications. |
State Management | The element of AUTOSAR Adaptive Platform defining modes of operation. It allows flexible definition of functions which are active on the platform at any given time. |
Function Group | A Function Group is a set of coherent Processes, which need to be controlled consistently. Depending on the state of the Function Group, Processes are started or terminated. Processes can belong to more than one Function Group State (but at exactly one Function Group). "MachineState" is a Function Group with a predefined name, which is mainly used to control Machine lifecycle and Processes of platform level Applications. Other Function Groups are sort of general purpose tools used (for example) to control Processes of user level Applications. |
Function Group State | The state of a Function Group (except "MachineState"). It defines a set of active Applications for any certain situation. The set of Function Groups and their states is machine spe- cific and is deployed as part of the Machine Manifest. |
Machine State | The state of Function Group "MachineState" with some predefined states (Startup/Shutdown/Restart). |
Time Determinism | The results of a calculation are guaranteed to be available before a given deadline. |
Data Determinism | The results of a calculation only depend on the input data and are reproducible, assuming a given initial internal state. |
Full Determinism | Combination of Time and Data Determinism. |
Communication Management | A Functional Cluster within the Adaptive Platform Foundation |
Execution Manifest | Manifest file to configure execution of an Adaptive Appli- cation. An Execution Manifest is created at integration time and deployed onto a Machine together with the Exe- cutable to which it is attached. It supports the integration of the Executable code and describes the configuration properties (startup parameters, resource group assignment etc.) of each Process, i.e. started instance of that Executable. |
Machine Manifest | Manifest file to configure a Machine. The Machine Man- ifest holds all configuration information which cannot be as- signed to a specific Executable or Process. |
Operating System | Software responsible for managing Processes on a Machine and for providing an interface to hardware resources. |
ResourceGroup | Configuration element to enable restrictions on resources uses by Adaptive Applications running in the group. |
ExecutionClient | Adaptive Application interface to Execution Manage- ment. |
DeterministicClient | Adaptive Application interface to Execution Manage- ment to support control of the process-internal cycle, a determin- istic worker pool, activation time stamps and random numbers. |
StateClient | State Management interface to Execution Management to support Function Group State and Machine State man- agement. |
Platform Health Management | A Functional Cluster within the Adaptive Platform Foundation |
Recovery Action | Actions defined by the integrator to control Adaptive Appli- cation error recovery. |

132 Specification of EEPROM Driver
2 Acronyms and abbreviations
Acronym | Description |
---|---|
Data block | A data block may contain 1..n bytes and is used within the API of the EEPROM driver. Data blocks are passed with, Address offset in EEPROM, Pointer to memory location, Length to the EEPROM driver. |
Data unit | The smallest data entity in EEPROM. The entities may differ for read/write/erase operation. |
Example 1(EEPROM Data unit) | Motorola STAR12 Read: 1 byte, Write: 2 bytes,Erase: 4 bytes |
Example 2(EEPROM Data unit) | external SPI EEPROM device Read/Write/Erase: 1 byte |
Normal mode Burst mode | Some external SPI EEPROM devices provide the possibility of different access modes: |
Normal mode | The data exchange with the EEPROM device via SPI is performed byte wise. This allows for cooperative SPI usage together with other SPI devices like I/O ASICs, external watchdogs etc. |
Burst mode | The data exchange with the EEPROM device via SPI is performed block wise. The block size depends on the EEPROM properties, an example is 64 bytes. Because large blocks are transferred, the SPI is blocked by the EEPROM access in burst mode. This mode is used during ECU start-up and shut-down phases where fast reading/writing of data is required. |
EEPROM cell | Smallest physical unit of an EEPROM device that holds the data. Usually 1 byte. |

2 Definitions and Acronyms
This section defines terms that are of special significance to the ECU Manager and the acronyms of related modules.
Term | Description |
---|---|
Callback | Refer to the Glossary [7] |
Callout | ‘Callouts’ are function stubs that the system designer can replace with code, usually at configuration time, to add functionality to the ECU Manager module. Callouts are separated into two classes. One class provides mandatory ECU Manager module functionality and serves as a hardware abstraction layer. The other class provides optional functionality. |
Integration Code | Refer to the Glossary [7] |
Mode | A Mode is a certain set of states of the various state machines (not only of the ECU Manager) that are running in the vehicle and are relevant to a particular entity, an application or the whole vehicle |
Passive Wakeup | A wakeup caused from an attached bus rather than an internal event like a timer or sensor activity. |
Phase | A logical or temporal assembly of ECU Manager’s actions and events, e.g. STARTUP, UP, SHUTDOWN, SLEEP, ...Phases can consist of Sub-Phases which are often called Sequences if they above all exist to group sequences of executed actions into logical units. Phases in this context are not the phases of the AUTOSAR Methodology. |
Shutdown Target | The ECU must be shut down before it is put to sleep, before it is powered off or before it is reset. SLEEP, OFF, and RESET are therefore valid shutdown targets. By selecting a shutdown target, an application can communicate its wishes for the ECU behavior after the next shutdown to the ECU Manager module. |
State | States are internal to their respective BSW component and thus not visible to the application. So they are only used by the BSW’s internal state machine. The States inside the ECU Manager build the phases and therefore handle the modes. |
Wakeup Event | A physical event which causes a wakeup. A CAN message or a toggling IO line can be wakeup events.Similarly, the internal SW representation, e.g. an interrupt, may also be called a wakeup event. |
Wakeup Reason | The wakeup reason is the wakeup event that is the actual cause of the last wakeup. |
Wakeup Source | The peripheral or ECU component which deals with wakeup events is called a wakeup source. |

2.1 Term and definition
Term | Description |
---|---|
Log and trace message | A log and trace message contains all data and options to describe a log and trace event in a software. A log and trace message consists of a header and payload. |
Dlt User | A Dlt User represents the source of a generated Dlt message. The possible users are SW-Cs, RTE (for VFB traces), DEM, or DET. |
Log Message | A Log Message contains debug information like state changes or value changes. |
Trace Message | A Trace messages contains information, which has passed via the VFB. |
ECU ID | ECU ID is the name of an ECU, composed by four 8-bit ASCII characters (e.g., ABS0 or COMB). |
Session | A session is a logical entity of source of log or trace messages. If an application / SW-C is instantiated several times, each instance gets a globally unique session ID with respect to the application / context ID. It is possible for an application / SWC to have several simultaneous log or trace sessions, if it has several ports opened to Dlt. Since Session ID is not specified in AUTOSAR for SW-Cs, the port defined argument values shall be used for this number. |
Session ID | Session ID is the identification number of a log or trace session. |
Application ID | Application ID is an abbreviation of an application / SW-C. It identifies the application / SW-C a log and trace message originates from. The Application ID is composed by four 8-bit ASCII characters. |
Context ID | Context ID is a user defined identifier to group Log and Trace Messages generated by an application / SW-C. The following rules apply: Each ApplicationID can own several Context IDs. Context IDs are grouped by Application IDs. Context IDs shall be unique within an Application ID. The source of a log and trace message is identified using the tuple “ApplicationID” and “ContextId”. Four 8-bit ASCII characters compose the ContextId. |
Message ID | Messaged ID is the identifier to characterize the information, which is transported by the message itself. A Message ID identifies a kind of log or trace message uniquely. It can be used for identifying the source (in source code) of a message and it can be used for characterizing the payload of a message. A Message ID is statically fixed at development or configuration time. |
Log level | A log level defines a classification for the severity grade of a Log Message. |
Trace status | The trace status provides information, if a trace message should be send. |
Log Channel | A physical communication bus, which is used to transmit Dlt messages. |
External client | The external client is a tool to control, monitor, and store log / trace messages provided by ECUs using the Dlt module. |

DTC group | Uniquely identifies an set of DTCs. A DTC group is mapped into the range of valid DTCs. By providing a group of DTCs it is ex- pressed that a certain operation is requested on all DTCs of that group. The DTC group definition is provided by ISO 14229-1[2] and OEM/supplier specific. |
DtcGroupAllDtcs | Grouping of all configured DTCS (representation is 0xFFFFFF). |
Event combination | Event combination is a method to merge several events to one specific combined DTC. It is used to adapt different monitor re- sults to one significant fault, which is clearly evaluable in a service station. |
Event debouncing | Debouncing is a specific mechanism (e.g. counter-based) to evaluate, if the diagnostic event gets qualified. This works on top of potential signal debouncing and can be done within the SW-C or inside the Dem. |
Event confirmation | A diagnostic event is confirmed in case of repeated detection of qualified events over cycles or time evaluated by means of fault confirmation counters. Therefore, also the UDS status bit 3 (Con- firmedDTC) is set. |
Event memory | An event memory (e.g. Primary memory) consists of several event memory entries. |
Event memory entry | The event memory entry is a single storage container for an event and its event related data. The event memory entry is dynami- cally assigned to specific events. |

If the counter reaches the threshold (e.g., 2 driving cycles) the con- firmed bit changes from 0 to 1. |
Fault Detection Counter | sint8 value as used in ISO and FDC-APIs. |
Freeze frame | Freeze frame is defined as a record of data (DIDs/PIDs). Freeze frames are the same as SnapShotRecords in ISO-14229-1[2]. |
General Denominator | The general denominator is a counter indicating the number of times a vehicle has been operated, taking into account general conditions. |
Healing | Switching off the warning indicator including the handling of re- ported passed results over a period of time / several operation cycles |
In-Use performance ratio | The in-use performance ratio (IUPR) of a specific monitor m of the OBD system is: IUPRm = Numeratorm / Denominatorm |
Master ECU | As a primary ECU a Master ECU stores “it’s own” and “reported errors” of related dep. / sec ECUs in it’s event memory. Beside this a Master has to fulfill special Master tasks as MIL Master or provision of “general nominator” information. |
Monitor | A diagnostic monitor is a routine entity determining the proper functionality of a component. Alternatively the term “diagnostic function” can be used. |
Numerator | The numerator of a specific monitor m (Numeratorm) is a counter indicating the number of times a vehicle has been operated such that all monitoring conditions necessary for that specific monitor to detect a malfunction have been encountered. |
NvM is marked for NvM_WriteAll | The Dem has called NvM_SetRamBlockStatus() to set the ac- cording NvM Block to be written by NvM_WriteAll() |
Operating cycle | An ‘operation cycle’ is the base of the event qualifying and also Dem scheduling (e.g. ignition key off-on cycles, driving cycles, etc.) |
OBD | On-Board Diagnostics, or OBD is a generic term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or a repair technician access to state of health information for various vehicle sub-systems. |
OBD ECUs | "In a vehicle there can be 3 different types of OBD ECUs:• Master ECU (one per vehicle) • Primary ECUprimary ECUs (several per vehicle) • Dependent / Secondary ECUs (several per vehicle) |
Positive Callback from NvM | The Dem module shall use the APIs NvM_WriteBlock and NvM_GetErrorStatus of the NVRAMManager [5], if there is the necessity to store data between Dem_Init and Dem_Shutdown. Furthermore the API NvM_GetErrorStatus shall wait for positive response if writing of block completed successfully. |
PossibleErrors | PossibleErrors means the ApplicationErrors as defined in meta model |
Primary ECU | A primary ECU stores “it’s own” and "reported errors" of related dep. / sec ECUs in it’s event memory |

2 Acronyms and Abbreviations
The glossary below includes acronyms and abbreviations relevant to the module that are not included in the [6, AUTOSAR glossary].
Abbreviation / Acronym | Description |
---|---|
Application Layer | The Application Layer is placed above the RTE. Within the Appli- cation Layer the AUTOSAR Software-Components are placed. |
Atomic Sender/Receiver inter- face | An atomic sender-receiver interface can be used to group DID data elements into one record data element prototype. All data elements can be read or write having a single read or write oper- ation. |
Channel | A link at which a data transfer can take place. If there is more than one Channel, there is normally some kind of ID assigned to the Channel. |
Diagnostic Channel | A link at which a data transfer between a diagnostic tool and an ECU can take place. Example: An ECU is connected via CAN and the diagnostic channel has an assigned CAN-ID. Diag- nostic channels connected to other bus-systems such as MOST, FlexRay, LIN, etc. are also possible. |
External Diagnostic Tool | A device which is NOT permanently connected to the vehicle communication network. This External Diagnostic Tool can be connected to the vehicle for various purposes, as e.g. for: • development • manufacturing • service (in a garage) Example External Diagnostic Tools are: • a diagnostic tester • an OBD scan tool. The External Diagnostic Tool is to be connected by a mechanic to gather information from ”inside” the car. |
Freeze Frame | A set of the vehicle/system operation conditions at a specific time. |
Functional Addressing | The diagnostic communication model where a group or all nodes of a specific communication network receive a message from one sending node (1-n communication). This model is also referred to as ’broadcast’ or ’multicast’. OBD communication will always be done in the Functional Addressing mode. |
Internal Diagnostic Tool | A device/ECU which is connected to the vehicle communication network. The Internal Diagnostic Tool can be used for: • advanced event tracking • advanced analysis • for service. The behavior of the Internal Diagnostic Tool can be the same as of an External Diagnostic Tool. The notion of ”Internal Diagnos- tic Tool” does not imply that it is included in each ECU as an AUTOSAR Software-Component. |
Physical Addressing | The diagnostic communication model where a node of a specific communication network receives a message from one sending node (1-1 communication). This model is also referred to as ’uni- cast’. |
UDS Service | this refers to a UDS Service as defined in ISO14229-1 [1]. |
OBD Service | This refers to an OBD Service as defined in ISO15031-5 [2]. |
AddressAndLengthFormat Identifier | Defines the number of bytes used for the memoryAddress and memorySize parameter in the request messages. |

Crypto Driver Object | A Crypto Driver implements one or more Crypto Driver Objects. The Crypto Driver Object can offer different crypto primitives in hardware or software. The Crypto Driver Objects of one Crypto Driver are independent of each other. There is only one workspace for each Crypto Driver Object (i.e. only one crypto primitive can be performed at the same time) |
Key | A Key can be referenced by a job in the Csm. In the Crypto Driver, the key refers a specific key type. |
Key Type | A key type consists of refers to key elements. The key types are typically pre-configured by the vendor of the Crypto Driver. |
Key Element | Key elements are used to store data. This data can be e.g. key material or the IV needed for AES encryption. It can also be used to configure the behaviour oft he key management functions. |
Job | A Job is a configured 'CsmJob'. Among others, it refers to a key, a cryptographic primitive and a reference channel. |
Channel | A channel is the path from a Crypto Service Manager queue via the Crypto Interface to a specific Crypto Driver Object. |
Primitive | A primitive is an instance of a configured cryptographic algorithm realized in a Crypto Driver Object. Among others it refers to a functionality provided by the CSM to the application, the concrete underlining 'algorithmfamily' (e.g. AES, MD5, RSA, etc.), and a 'algorithmmode' (e.g. ECB, CBC, etc). |
Operation | An operation of a crypto primitive declares what part of the crypto primitive shall be performed. There are three different operations: |
START | Operation indicates a new request of a crypto primitive, it shall cancel all previous requests perform necessary initializations and checks if the crypto primitive can be processed. |
UPDATE | Operation indicates, that the crypto primitive expect input data. An update operation may provide intermediate results. |
FINISH | Operation indicates, that after this part all data are fed completely and the crypto primitive can finalize the calculations. A finish operation may provide final results. It is also possible to perform more than one operation at once by concatenating the corresponding bits of the operation_mode argument. |
Priority | The priority of a job defines the importance of it. The higher the priority (as well in value), the more immediate the job will be executed. The priority of a cryptographic job is part of the configuration. |
Processing | Indicates the kind of job processing. |
Asynchro nous | The job is not processed immediately when calling a corresponding function. Usually, the caller is informed via a callback function when the job has been finished. |
Synchron ous | The job is processed immediately when calling a corresponding function. When the function returns, a result will be available. |
Service | A service shall be understand as defined in the TR_Glossary document: A service is a type of operation that has a published specification of interface and behavior, involving a contract between the provider of the capability and the potential clients. |

OSEK/VDX | In May 1993 OSEK has been founded as a joint project in the German automotive industry aiming at an industry standard for an open-ended architecture for distributed control units in vehicles. OSEK is an abbreviation for the German term "Offene Systeme und deren Schnittstellen für die Elektronik im Kraftfahrzeug" (English: Open Systems and the Corresponding Interfaces for Automotive Electronics). Initial project partners were BMW, Bosch, DaimlerChrysler, Opel, Siemens, VW and the IIIT of the University of Karlsruhe as co-ordinator. The French car manufacturers PSA and Renault joined OSEK in 1994 introducing their VDX-approach (Vehicle Distributed eXecutive) which is a similar project within the French automotive industry. At the first workshop on October 1995 the OSEK/VDX group presented the results of the harmonised specification between OSEK and VDX. After the 2nd international OSEK/VDX Workshop in October 1997 the 2nd versions of the specifications were published. |

Term | Description: |
---|---|
AUTOSAR COM | The AUTOSAR COM module is derived from [17]. For details, see Chapter 7.2.1. |
Confirmation | With a Confirmation, the PDU Router reports that a request by the AUTOSAR COM module has been completed successfully. It is a reaction to a request of COM. E.g. when a PDU has been successfully transmitted. |
Data Invalid Value | Value sent by the AUTOSAR COM module to indicate that the sender side AUTOSAR Software Component is not able to provide a valid value. |
Dynamic Length Signal | A dynamic length signal is a signal which length can vary at run-time. |
Dynamic Length I-PDU | A dynamic length I-PDU is an I-PDU containing a dynamic length signal. It length varies depending on the length of the included dynamic length signal. |
Group signal | A group signal is a signal that is contained in a signal group. |
Indication | An Indication is asynchronous information from PDU Router to COM, e.g. to acknowledge that something has been received. |
Init Value | I-PDUs and signals are set to the Init Value by the AUTOSAR COM module after start-up. This value is used until it is overwritten. |
I-PDU group | An I-PDU Group is an arbitrary collection of I-PDUs of the same direction (i.e. send or receive) in the COM module. |
Inter-ECU–communication | Communication between two or more ECUs for example via a CAN network |
Intra-ECU–communication | Communication between Software components that reside on the same ECU |
Large Signal | A large signal is a signal that is too large to fit into a single L-PDU of the underlying communication protocol. |
Large I-PDU | Large I-PDUs are I-Signal-I-PDUs which do not fit into a single L-PDU of the underlying communication protocol. Large I-PDUs will be handled like other Specification of Communication I-PDUs by COM, but are transmitted/received via the TP API. Please note that large I-PDUs can also be handled in a more efficient way by LargeDataCOM if they contain just one signal, or if the signals can be (de-)serialized by the RTE. But if the signals have to be treated separately or have to be routed, the large I-PDUs have to be handled by COM. |
Message | [17] uses always the synonym message. In AUTOSAR, message is replaced by signal but with the same meaning. |
Metadata | For some I-PDUs, e.g. J1939 I-PDUs, the payload is extended with additional metadata containing for example the CAN-ID. |
Notification | Information by the AUTOSAR COM module to RTE, e.g. when new data is available, an error occurred. |
Signal | A signal in the AUTOSAR COM module’s context is equal to a message in [17]; see also [7]. |
Signal group | In AUTOSAR, so called complex data types are used. Inside a complex data type, there are one or more data elements (primitive data types), like in a C struct. The data consistency of such complex data types must be ensured. The RTE decomposes the complex data type in single signals and sends them to the AUTOSAR COM module. As these signals altogether need to be treated consistently, they are called signal group. See also [7]. |
Update-bit | A mechanism supported by the AUTOSAR COM module with that the receiver of a signal/ signal group could identify whether the sender has updated the data in this signal/ signal group before sending. See Chapter 7.9. |

All acronyms and abbreviations, which are specific to the CAN Transport Layer andvare therefore not contained in the AUTOSAR glossary, are described in the following:
Acronym | Description |
---|---|
CAN L-SDU | This is the SDU of the CAN Interface module. It is similar to CAN N-PDU but from the CAN Interface module point of view. |
CAN LSduId | This is the unique identifier of a SDU within the CAN Interface. It is used for referencing L-SDU’s routing properties. Consequently, in order to interact with the CAN Interface through its API, an upper layer uses CAN LSduId to refer to a CAN L-SDU Info Structure. |
CAN N-PDU | This is the PDU of the CAN Transport Layer. It contains a unique identifier, data length and data (protocol control information plus the whole N-SDU or a part of it). |
CAN N-SDU | This is the SDU of the CAN Transport Layer. In the AUTOSAR architecture, it is a set of data coming from the PDU Router. |
CAN N-SDU Info Structure | This is a CAN Transport Layer internal constant structure that contains specific CAN Transport Layer information to process transmission, reception, segmentation and reassembly of the related CAN N-SDU. |
CAN NSduId | Unique SDU identifier within the CAN Transport Layer. It is used to reference NSDU’s routing properties. Consequently, to interact with the CAN Transport Layer via its API, an upper layer uses CAN NSduId to refer to a CAN N-SDU Info Structure. |
I-PDU | This is the PDU of the AUTOSAR COM module. |
PDU | In layered systems, it refers to a data unit that is specified in the protocol of a given layer. This contains user data of that layer (SDU) plus possible protocol control information. Furthermore, the PDU of layer X is the SDU of its lower layer X-1 (i.e. (X)-PDU = (X-1)-SDU). |
PduInfoType | This type refers to a structure used to store basic information to process the transmission\reception of a PDU (or a SDU), namely a pointer to its payload in RAM and the corresponding length (in bytes). |
SDU | In layered systems, this refers to a set of data that is sent by a user of the services of a given layer, and is transmitted to a peer service user, whilst remaining semantically unchanged. |

Definitions | Description: |
---|---|
Default Error Tracer | The Default Error Tracer is merely a support to SW development and integration and is not contained in the production code. The API is defined, but the functionality can be chosen and implemented by the developer according to his specific needs. |
Diagnostic Event Manager | The Diagnostic Event Manager is a standard AUTOSAR module which is available in the production code and whose functionality is specified in the AUTOSAR project. |
Extended addressing format | A unique CAN identifier is assigned to each combination of N_SA and Mtype. A unique address is filed to each combination of N_TA and N_TAtype in the first data byte of the CAN frame data field. N_PCI and N_Data are filed in the remaining bytes of the CAN frame data field. |
Function Inhibition Manager | The Function Inhibition Manager (FIM) stands for the evaluation and assignment of events to the required actions for Software Components (e.g. inhibition of specific “monitoring functions”). The DEM informs and updates the Function Inhibition Manager (FIM) upon changes of the event status in order to stop or release functional entities according to assigned dependencies. An interface to the functional entities is defined and supported by the Mode Manager. The FIM is not part of the DEM. |
Functional addressing | In the transport layer, functional addressing refers to N-SDU, of which parameter N_TAtype (which is an extension to the N_TA parameter [14] used to encode the communication model) has the value functional.This means the N-SDU is used in 1 to n communications. Thus with the CAN protocol, functional addressing will only be supported for Single Frame communication. In terms of application, functional addressing is used by the external (or internal) tester if it does not know the physical address of an ECU that should respond to a service request or if the functionality of the ECU is implemented as a distributed server over several ECUs. When functional addressing is used, the communication is a communication broadcast from the external tester to one or more ECUs (1 to n communication). Use cases are (for example) broadcasting messages, such as “ECUReset” or “CommunicationControl” OBD communication will always be performed as part of functional addressing. |
Mixed addressing format | A unique CAN identifier is assigned to each combination of N_SA, N_TA, N_TAtype. N_AE is placed in the first data byte of the CAN frame data field. N_PCI and N_Data are placed in the remaining bytes of the CAN frame data field. |
Multiple connection | The CAN Transport Layer should manage several transport protocol communication sessions at a time. |
Normal addressing format | A unique CAN identifier is assigned to each combination of N_SA, N_TA, N_TAtype and Mtype. N_PCI and N_Data are filed in the CAN frame data field. |
Physical addressing | In the transport layer, physical addressing refers to N-SDU, of which parameter N_TAtype (which is an extension of the N_TA parameter [14] used to encode the communication model) has the value physical. This means the N-SDU is used in 1 to 1 communication, thus physical addressing will be supported for all types of network layer messages. In terms of application, physical addressing is used by the external (or internal) tester if it knows the physical address of an ECU that should respond to a service request. When physical addressing is used, a point to point communication takes place (1 to 1 communication). Use cases are (for example) messages, such as “ReadDataByIdentifier” or “InputOutputControlByIdentifier” |
Single connection | The CAN Transport Layer will only manage one transport protocol communication session at a time. |
Connection channel | The CAN Transport Layer is handling resources used by multiple connections in order to save RAM. When a connection becames active, the channel that is used by this connection will be unavailable for other connections. |
Connection | A transport protocol session, either is a transmission or a reception session on a NSDU. |

term | Description |
---|---|
ADC HW Unit | Represents a microcontroller input electronic device that includes all parts necessary to perform an “analogue to digital conversion”. |
ADC Module | ADC Basic Software module ADC Driver, abbreviated also with ADC Driver |
ADC Channel | Represents a logical ADC entity bound to one port pin. Multiple ADC entities can be mapped to the same port pin. |
ADC Channel Group | A group of ADC channels linked to the same ADC hardware unit (e.g. one Sample&Hold and one A/D converter). The conversion of the whole group is triggered by one trigger source. |
ADC Result Buffer(ADC Streaming Buffer, ADC Stream Buffer) | The user of the ADC Driver has to provide a buffer for every group. This buffer can hold multiple samples of the same group channel if streaming access mode is selected. If single access mode is selected one sample of each group channel is held in the buffer. |
Software Trigger | Software API call that starts the conversion of one ADC channel group or a continuous series of ADC channel group conversions. |
Hardware Trigger | ADC internal trigger signal that starts one conversion of an ADC channel group. |
ADC hardware trigger are generated internally in the ADC hardware, e.g. based on an ADC timer or a trigger edge signal. The trigger hardware is tightly coupled or integrated in the ADC hardware. No software is required to start the ADC channel group conversion after the hardware trigger is detected. Note: If the ADC hardware does not support hardware trigger, a similar behavior can be realized with software trigger in combination with the GPT/ICU driver. E.g. in a GPT timer notification function a software triggered ADC channel group conversion can be started. | |
Conversion Mode One-Shot | The conversion of an ADC channel group is performed once after a trigger and the results are written to the assigned result buffer. A trigger can be a software API call or a hardware event. |
Conversion Mode Continuous | The conversions of an ADC channel group are performed continuously after a software API call (start) and the results are written to the assigned result buffer. The conversions themselves are running automatically (hardware/interrupt controlled). The Continuous conversions can be stopped by a software API call (stop). |
Sampling Time, Sample Time | Time during which the analogue value is sampled (e.g. loading the capacitor, …) |
Conversion Time | Time during which the sampled analogue value is converted into digital representation. |
Acquisition Time | Sample Time + Conversion Time. |

Definition | Description |
---|---|
Off-Mode | The watchdog hardware is disabled / shut down. This might be necessary in order to shut down the complete ECU and not get cyclic resets from a still running external watchdog. This mode might not be allowed for safety critical systems. In this case, the Wdg module has to be configured to prevent switching to this mode. |
Slow-Mode | Triggering the watchdog hardware can be done with a long timeout period. This mode can e.g. be used during system startup / initialization phase. E.g. the watchdog hardware is configured for toggle mode (no constraints on the point in time at which the triggering is done) and a timeout period of 20 milliseconds. |
Fast-Mode | Triggering the watchdog hardware has to be done with a short timeout period. This mode can e.g. be used during normal operations of the ECU. E.g. the watchdog hardware is configured for window mode (triggering the watchdog has to occur within certain minimum / maximum boundaries within the timeout period) and a timeout period of 5 milliseconds |
