Embitel’s Next-Gen AUTOSAR Solutions
Driving Scalable, Interoperable, and Future-Ready Automotive Solutions
Automotive industry is heading towards an ecosystem where software isn’t a tangled web of incompatibilities. And AUTOSAR is the gateway to achieve such interoperability and standardization.
Adopting AUTOSAR resolves challenges for OEMs and tier-1s such as proprietary software constraints, costly integration, and varying quality. It ensures compatibility across platforms, simplifies software updates, and fosters collaboration, allowing seamless interfaces among diverse vendor modules.
AUTOSAR is the universal language of modern automotive software. OEMs and tier-1s are often cornered by vendor lock-ins, facing integration nightmares and mounting costs. AUTOSAR mitigates such issues by eliminating the disparities between ECUs, creating a unified and predictable environment.
Embitel provides comprehensive AUTOSAR solutions tailored for today’s automotive challenges.
Our expertise encompasses BSW (Basic Software) configuration, MCAL (Microcontroller Abstraction Layer) development, and specialized CDD (Complex Device Driver) creation.
Our AUTOSAR Success Stories
Development of AUTOSAR Compliant FLS Driver and Configuration Tool
Embitel developed an FLS driver per AUTOSAR specifications, separating the watchdog reset function from the main function, and resolving the timer reset challenge. Additionally, a Python-based tool was crafted for configuring the FLS driver according to parameters. We also assisted in the integration of the FLS driver with the system's other modules.
AUTOSAR Compliant ECU Software Development
We developed AUTOSAR compliant ECU software to control camera positions at the car's front and rear, thereby managing its front and rear views. Using the DaVinci Developer tool, we crafted the software architecture and modeled each component with TargetLink 3.1, which also enabled automated code production.
AUTOSAR MCAL, BSW And RTE Integration for an Automotive Tier-1
We supported an automotive tier-1 in transitioning the Battery Monitoring ECU software to a new microcontroller while migrating from a legacy to AUTOSAR architecture. By using tools like COMASSO and Vector Da-Vince, we successfully redesigned the ECU architecture, ensuring a harmonious integration of both AUTOSAR and non-compliant components.

- What is AUTOSAR 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).
- Why migrate to AUTOSAR architecture from legacy software?
- Benefits of migrating to AUTOSAR architecture:
- 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)

- Which tools are used for AUTOSAR software development and AUTOSAR 4.3 Migration? What are their roles?
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)
