AUTOSAR embedded software implementation

The AUTOSAR standard is founded on the ability to bring software vendors together to collaborate so they can efficiently produce ECU software.

The software is made up of:

• Software components in the application layer
• Hardware driver support through microcontroller abstraction layer and ECUs custom device drivers

They are joined by the basic software abstracted from the application software via a runtime environment.

Capital Embedded AR Classic adheres closely to the AUTOSAR methodology and includes native support for the AUTOSAR model. Tool features like configuration splitability greatly simplify processes for ECU software developers.

Capital Embedded AR Adaptive similarly adapts the latest AUTOSAR methodology with the Adaptive platform models and methods, and enhances this with advanced automation in the developer-first tooling, enabling rapid high quality deployments of software.

Driven by demands, including innovative customer features and functional safety requirements, software engineering teams need to increase the pace of development and improve quality. This requires new levels of efficiency. Enabling software development to ‘shift-left’ by moving verification and validation (V&V) earlier in the design process is a key element to produce embedded software more efficiently. These V&V activities may be performed using actual embedded software on virtual ECUs to run extensive simulations. This technology enables the application of test automation in early development before target hardware is available and throughout the entire software lifecycle to improve coverage and execution visibility.

Throughout the vehicle lifecycle, embedded software updates are commonly needed for ECUs. Capital Embedded Bootloader supports reliable ECU updates during development, in-vehicle production and during the life of the vehicle via connected diagnostics tools or over-the-air methodologies. The standardized ISO 14229 UDS protocol is used over a range of common vehicle network buses, Ethernet, CAN/CAN-FD, LIN and FlexRay. It is also possible to use other methods such as the Association for Standardization of Automation and Measuring Systems (ASAM) calibration protocols. Cybersecurity is a key aspect of the software update flow and features, enabling software authentication and secure boot options. To satisfy original equipment manufacturer (OEM) and microcontroller unit (MCU)-specific requirements, wide support is available for a broad range of MCUs.
