AUTOSAR RS ECU CONFIGURATION PDF

Akira Since the foreign wcu SignalDefinitionSystemDescription is auhosar in the same container as the derived parameter definitions it is possible to address the reference directly using its name. The SW may either receive parameters of its configuration during the download of the complete ECU software resulting from the linkage of the code, or it may receive its configuration file that can be downloaded to the ECU separately, avoiding a re-compilation and re-build of the ECU SW modules. The configuration of the different modules is done in different sections of the overall description. Common to the different tool approaches is that each configuration autosxr must be capable of reading a possibly incomplete ECU Configuration Description and writing back its modified configuration autossar in the same format.

Tujar Custom Editors and Generators In the custom editors approach as shown in figure 2. Also ConfigReference is inheriting from ParamConfMultiplicity so for each reference definition it can be specified how many such references might be present in the same configuration container later in the ECU Configuration Description.

However, for several modules such as OS, existing configuration languages have already been established. But for some channels, this direction may be fixed by hardware and must thus be fixed in configuration. If XML files are used there is no conceptual limit in the number of files making up the description. It donfiguration not apply any additional semantics to the parameter. Since each configuration parameter is defined only once, all instances of the parameter will have the same initial value when the default values is taken as input to the base configuration.

String FunctionNameValue Figure 3. The preconfiguredConfiguration contains values for those parameters which are fixed by the implementation and cannot be changed. The complex dependencies between the BSW module configuration and other configuration items in the ECU Configuration Description could be expressed and supported in the tool.

In general the configuration language uses containers and actual parameters. Configuration of parameters can be done in any configueation these process-steps: But since the ECU Configuration is dependent on lots of other input information many values for the configuration of the BSW and the RTE can be taken over or calculated from other values already available in another description e.

For further rules how a value can be provided if no defaultValue is specified in the ECU Configuration Definition see section 4. Additionally it references all Software Module configurations see section 3. In general, the structure of the ECU Configuration Description metamodel follows the same approach the parameter definition is based upon. Two different approaches are shown. The values of this attribute should be globally unique strings prefixed by the type of identifier. Or if a configuration parameter is defined at post-build time the configuration parameter has to be stored at a known memory location.

This generation zutosar a semi-automatic process: Second, the Identifiable introduces the concept of a namespace for the contained Identifiable objects, so those objects need to have unique cohfiguration in the scope of that namespace. This iteration will initially be between editors and then, when a plausible Auotsar Configuration is achieved, code generation may highlight additional changes that require further iteration.

The overview is shown in figure 3. Generation is the process of applying the tailored ECU Configuration Description to the software modules. Student Financial Assistance Form.

BSW Modules have standard confiuration and configuration requirements. That means parameter values for those configurable elements are selected before compiling and will be effective after compilation time. This configuration class permits the change of configuration parameter value after building of SW module. One subcontainer instance is defined for each PDU received. As stated in section 2.

The flow of work products is depicted by solid lines with arrow heads, pointing in the direction of the work flow. The additional attributes min, max and defaultValue can be specified as well. A valid EcuConfiguration needs to reference the System description provided as an ecuExtract [7] that specifies the environment in which the configured ECU operates.

With this feature functions like callbacks can be specified. TOP Related Posts.

Vibar This is done using object diagrams this is the M1 level of metamodeling with special semantics defined in section 3. ParameterValue All specialized parameter values that are derived from ParameterValue are described in the sections below. It would read those definitions and provide a generic interface to edit values for all parameters in the ECU Configuration Description. Example of an object diagram for a foreign reference In the example in figure 3. Or if a configuration parameter is defined at post-build time the configuration parameter has to be stored at a known memory location.

Shak The overview is shown in figure 3. There are output file formats other than. Class diagram for parameter container definition [ecuc sws ] A ParamConfContainerDef is the main container class definition and can contain other containers, configuration parameters and references. Certain aspects of real application configurations are already defined: The examples for the individual parameters are taken ceu figure 3. The configuration classes are explained in detail in following section of this cohfiguration.

Gamuro If any of the aggregated parameters is either preCompile time or link time this attribute is ignored and may be ommited. Sample cases where Link Time configuration can be adopted are listed below: Second, a choice in the referenced configuration container can be specified and the ECU Configuration Description has the freedom with restrictions to choose to which target type the reference is pointing to. Parameter references Class Package Class Desc. It would read those definitions and provide a generic interface to edit values for all parameters in the ECU Configuration Description. This can be performed in different ways, and is dependent on the configuration classes configueation for the different modules see chapter 2. This generation is a semi-automatic process: Otherwise both attributes are shown. This holds for module definitions, container definitions and individual parameters.
