AUTOSAR Software Development

Standardize your automotive software with our AUTOSAR Software development services

Adopting AUTOSAR (Automotive Open System Architecture) resolves a number of key issues in automotive software development. AUTOSAR is able to do so by introducing standardization and modularity.

As automotive systems become more complex with increasing functionality, managing this complexity efficiently is crucial. AUTOSAR architecture provides a standardized platform that organizes and simplifies the development process.

With components sourced from various suppliers, ensuring compatibility and interoperability is a challenge. AUTOSAR defines a common set of standards that all components must adhere to, ensuring that they can work seamlessly together.

And most importantly, AUTOSAR architecture supports the implementation of safety-critical applications according to industry standards like ISO 26262. It provides mechanisms for error handling and functional safety that are essential in modern vehicles.

One solution for a lot of problems!

Knowledge bytes

AUTOSAR MCAL is a software module that directly accesses on-chip MCU peripheral modules and external devices that are mapped to memory, and makes the upper software layer independent of the MCU.
(Source – Renesas)
AUTOSAR uses a three-layered architecture:
  • Basic Software (AUTOSAR BSW): Basic Software is the standardized software layer, which provides services to the AUTOSAR Software Components and is necessary to run the functional part of the software. It does not fulfill any functional job itself and is situated below the AUTOSAR RTE (Runtime Environment). The Basic Software contains standardized and ECU specific modules.
  • Runtime environment (AUTOSAR RTE): Middleware which abstracts from the network topology for the inter- and intra-ECU information exchange between the application software components and between the Basic Software (BSW) and the applications.
  • Application Layer: application software components that interact with the runtime environment (RTE).
Source – AUTOSAR.org
AUTOSAR layered architecture ensures a clear demarcation between the application software and hardware platform and drivers with the help of RTE. This facilitates a shift in ECU design approach from coding to configuration
  • Improved reuse of ECUs in new car platforms and architectures
  • Improved use of pre-validated and tested software components (representing vehicle functions)
  • Reduced testing and safety certification costs
  • Reduction in downstream design errors—an AUTOSAR methodology allows functions to be defined and verified at an architectural level
  • Reduction in overall hardware cost by improved AUTOSAR network management and capacity utilization
  • Reduced costs in overall network architecture analysis and design reviews
  • Improved communication between OEMs and Tier 1 suppliers, by using a standardized digital exchange format (AUTOSAR XML or arxml)

A number of AUTOSAR tools are deployed to develop an AUTOSAR compliant software. These tools are also very important for projects involving migration to AUTOSAR 4.3 or other versions.

Here is a list of tools that our AUTOSAR software developers are expert in:

  • COMASSO: COMASSO is a registered association that supports implementation of the AUTOSAR Architecture as per the common global standard. (Source- https://www.comasso.org/).COMASSO provides a technical platform to the AUTOSAR software developers in order to reduce the integration efforts in software exchange or re-use.COMASSO as a platform facilitates AUTOSAR developers to maintain and develop AUTOSAR BSW as part of a community, which is similar to an Open Source community.COMASSO technical platform also helps the developers exchange source code, information and experience to implement AUTOSAR BSW.
  • KPIT K-SAR AUTOSAR Suite: It is used by AUTOSAR Software developers to configure and generate AUTOSAR BSW (Base Software) and AUTOSAR RTE (Run-time Environment).The tool comprises of basic AUTOSAR Software Stack and K-SAR Editor.
  • DaVinci Developer Tool from Vector: It is a development tool for designing the architecture of software components, that need to be deployed in AUTOSAR based Electronic Control Systems.It is used in application development phase of AUTOSAR software development projects.One of the tool’s biggest advantage is its ability to link model based development (MBD) tools via ARXML (a file format introduced by AUTOSAR to contain data used in Electronic Control Unit(ECU) development as per the AUTOSAR Architecture)
