What is AUTOSAR container?

Containers are named as such because containers contain Configuration parameters. A container /sub container can refer to other container/sub container, now the reference can hold a multiplicity value, multiplicity then defines the possible number of instances of the contained parameters.

What is variant handling?

Variant handling in AUTOSAR is about documenting variants at the ECU level to describe design information.

Can configuration within AUTOSAR?

What is CAN Communication Stack in AUTOSAR Architecture? When the target Bus type for an AUTOSAR compliant software is CAN, the ComStack implementation is executed with respect to CAN Bus. Right from the Interface (IF) and State Manager to low-level drivers, each of these modules need to be configured for CAN Bus.

What is System description file in AUTOSAR?

The supplier or OEM defines the SWCs. This involves creating an XML file for each SWC: the SWC Description. The supplier or OEM then creates the relevant C files for the implementation. System Description: The OEM first defines, based on the SWCs, the functional content for the entire vehicle independent of the ECUs.

What is AUTOSAR configuration?

AUTOSAR provides for der- ivation of a basic configuration of the modules (the Base EcuC) from an ECU-specific extract of the system descrip- tion (System Extract). In practice, however, the situation is somewhat more complicated (Figure 3): AUTOSAR has de- fined a standard format for the system descriptions.

Which module is responsible for multiplexing the PDUs?

I-PDU Multiplexer module
Multiplexing of PDUs is currently known from CAN, but is not restricted to this com- munication system. On sender-side, the I-PDU Multiplexer module is responsible to combine appropriate I-PDUs from COM to new, multiplexed I-PDUs and send them back to the PDU Router.

What is variant coding car?

Variant coding is a process that enables automotive manufacturers to program a vehicle with particular variations. These variants are programmed according to the options specified on a particular vehicle model. This reduces the number of ECU part numbers for a particular car model.

CAN driver configuration?

The CanConfigSet contains configurations of CAN controllers and CAN hardware objects. CanControllerId is mapped to a controller and in MPC this means that 0=FLEXCAN_A, 1=FLEXCAN_B etc. 16 times 500000 is 8000000, select 16 time quantas per bit. Select sample point 75%.

What is PDU in CAN protocol?

In telecommunications, a protocol data unit (PDU) is a single unit of information transmitted among peer entities of a computer network. A layer lower in the Internet protocol suite, at the Internet layer, the PDU is called a packet, irrespective of its payload type.

What is system configuration in AUTOSAR?

Basically the AUTOSAR methodology allows for a high degree of reuse in this context. The activity of the Configure System mainly maps the software components to the ECUs with regard to resources and timing requirements. The output of the Configure System is the System Configuration Description.

What is XDM file in AUTOSAR?

arxml files are a type of files used across AUTOSAR , to configure the AUTOSAR software. arxml – includes parameters required to configure the basic software modules for one specific ECU.

What is post build configuration?

Post build is used to update parts of the configuration after compile time and is typically used by the OEM. The post build parameters are located in a separate memory area which may be replaced by a new configuration that may be downloaded independently of the other parts for the ECU software.

Where to find post build configuration in AUTOSAR?

Post-build time configurations are done in files *_PBcfg.c and *_PBcfg.h, ‘*’ specifies the module name. Post-build Loadable : In this configuration set, one configuration structure is available and individual members of the structure can be modified but the completely different structure cannot be selected.

What is a pre compile time configuration in AUTOSAR?

Pre-compile time configurations are static wherein the software modules will be effective, based on configuration, after compile time. It results in optimization of code size and performance. Pre-compile time configurations are done in file *_Cfg.c and *_Cfg.h, ‘*’ specifies the module name.

How to enable post build mode in BSW?

Open the post build project and make sure Post-build mode is enabled on the BSW Editor overview page. It is now only possible change all parameters and containers that have support for post build. Elements that is not editable will be grayed out.

What are the 3 variants of AUTOSAR modules?

I had gone through the specificaiton of CAN interface and I am in confusion about the 3 variants listed in specification. which are PRE_COMPILE, LINK_TIME, POST_BUILD, configuration. I understand the concept of all 3 but I am just not able to visualize the content of the files specified as *.Pbcfg.c, *.Cfg.c and *._Lcfg.c
