Such configuration parameters are called Derived Configuration Parameters. It is assumed that configuration editors perform consistency and completeness checks on the part of the configuration they support. Therefore it has multiple references of different type.

As stated in section 2. But the ECU Configuration editors need to know how the content of an ECU Configuration Description should be structured which parameters are available in which container and what kind of restrictions are to be respected e.

ModuleDef The ModuleDef finally aggregates containers with the role name container which may hold other containers and parameter definitions. First, the hardware defines the number of instances that can be configured.

Specification of ECU Configuration

autosae When specifying the containment relationship between two containers an aggregation with the role name subContainer at the contained container is used. If the configuration description would be provided without an according configuration definition an editor could not reconstruct what kind of ContainerDef a Container is based upon. This iteration will initially be between editors and then, when a plausible ECU Configuration is achieved, code generation may highlight additional changes that require further iteration.


ParamConfMultiplicity For examples please refer to figure 3. In the following, the different approaches that have been considered exu the development of the specification are introduced.

They are fully automatic, since all input driving these steps is included in the ECU Configuration Description. The available exu types are shown in figure 3. In the calculationFormula this is used to address the different parts the value needs to be derived from.

Specification of ECU Configuration

This approach has the advantage that the different formats can be tailored to the problem at hand, and they can be extended and adapted easily. The flow of work products is depicted by solid lines with arrow heads, pointing in the direction of the work flow.

There are three tags predefined to be used in the definition of the parameters: When CRC16 is selected, there will be increase in processing time but reduction in memory usage.

The different tool chain models given in sections 2. The value of the configurable parameter is decided in earlier stage of software development process and any changes in the parameter value calls for a re-compilation. The only additional attribute is the defaultValue which may be specified while defining the parameter. This is the last step of the configuration process and again out of scope of this specification.

This can be performed in different ways, and is dependent on the configuration classes chosen for the different modules see chapter 2. The upperMultiplicity of that container may be equal or less to what is defined in the StMD.


Dependencies are depicted by dashed lines with arrow heads, pointing from the dependent element to the element it depends on. Details on the System Configuration Description can be found in [7]. Parameter references Class Package Class Desc. Reference to the definition of this ModuleConfiguration.

Furthermore, module vendors may define additional configuration parameters to allow for configuration of hardware and implementation-specific details of their implementation. Neither their presence in such Specification Documents, nor any later AUTOSAR compliance certification of products actually implementing such exemplary items, imply that intellectual property rights covering such exemplary items are licensed under configurafion same rules as applicable to the AUTOSAR Standard.

Parameters hold the relevant values that configure the specific parts of an ECU. The module source file needs this header file to resolve the references and module configuration source file will need to cross check the declaration of data type against the definition. Configurwtion Class es Attribute Datatype Mul. Since the calculationFormula provides information how the values can be computed it utilizes the references to address foreign elements to gather the needed information.

String specifying if this configuration parameter is an AUTOSAR standardized configuration parameter or if the parameter is hardware- or vendor-specific.
