AUTOSAR Classic: A Comprehensive Guide to Safety and Cybersecurity in Automotive Software

AUTOSAR Classic

• AUTOSAR remains a key driver in automotive software development, providing a standard for embedded systems crucial for vehicle safety and cybersecurity
• TrustInSoft Analyzer enhances AUTOSAR Classic’s implementation, automating analysis driver generation and significantly streamlining the verification process.
• Early bug detection with TrustInSoft Analyzer not only saves time but eliminates runtime errors, supporting compliance with safety (ISO 26262) and cybersecurity (ISO 21434) standards.

The automotive industry is at the forefront of a technological revolution, driven by the increasing complexity of vehicle systems and the demand for robust and reliable software. In this era of interconnected and autonomous cars, ensuring safety and cybersecurity is paramount. This is where AUTOSAR takes center stage.

Navigating the AUTOSAR Landscape

AUTOSAR, or Automotive Open System Architecture, is an open standard meticulously developed by a consortium of automotive manufacturers and suppliers. Its primary goal is to establish a universal framework for software development and integration across diverse platforms and vehicle architectures. AUTOSAR comprises two main platforms: the Classic Platform, which is the focus of this blog post, and the Adaptive Platform.

AUTOSAR Classic: The Pillar of Embedded Systems

AUTOSAR Classic, the original platform, is specifically tailored for embedded systems with real-time and safety constraints. Its layered architecture separates application software from the underlying hardware, the runtime environment (RTE), and the basic software (BSW).

Safety and Cybersecurity: The Cornerstones of AUTOSAR

In the automotive industry, safety and cybersecurity are non-negotiable, particularly for AUTOSAR Classic deployed in critical systems like safety-critical Electronic Control Units (ECUs). AUTOSAR Classic plays a pivotal role in safeguarding vehicles and their occupants by ensuring the reliability of embedded software.

ARXML: Unveiling the Key to Automatic Analysis Drivers

AUTOSAR Classic standardized a specialized XML format called ARXML (AUTOSAR Application Release Package). This file contains information about software components, including interfaces, value ranges, and RTE usage calls. TrustInSoft Analyzer’s groundbreaking application of ARXML allows for the automatic generation of analysis drivers—a process that systematically analyzes the functionality of software components.

Streamlining verification with TrustInSoft Analyzer

The combination of ARXML data and TrustInSoft Analyzer, a sound static analyzer, streamlines the software verification process. This powerful combination offers several advantages:

• Increased Efficiency: Testers and developers can automatically generate analysis drivers, saving significant time and effort.
• Early Bug Detection: Shifting left in bug detection allows for the identification of subtle defects or flaws when source code files are available.
• Reduced User Fatigue: The TrustInSoft Analyzer yields zero false alarms.
• Elimination of Runtime Errors: Proving the absence of runtime errors eliminates the risk of undetected defects or flaws resulting from runtime errors, i.e. zero false negatives.

Revolutionizing Traditional Test Methods

While traditional test methods are essential, they can be time-consuming and labor-intensive. The combination of abstract interpretation with ARXML-based analysis driver generation provided by TrustInSoft Analyzer significantly enhances the efficiency and effectiveness of the verification process.

By embracing this innovative approach, automotive software suppliers can ensure that vehicles meet the highest standards of safety (ISO 26262) and cybersecurity (ISO 21434), ultimately protecting both drivers and passengers. AUTOSAR Classic, alongside cutting-edge tools like TrustInSoft Analyzer, stands as the cornerstone of excellence in automotive-embedded software development.
