What can Autosar Expert do for my AUTOSAR project?

Autosar Expert is an AI assistant that helps engineers with AUTOSAR tasks: it analyzes ARXML snippets, proposes RTE interface layouts, generates SWC skeletons and configuration templates, suggests BSW module parameterization, drafts integration checklists, creates test-case outlines and documentation, and advises on migration between AUTOSAR Classic and Adaptive. Outputs are intended as engineering templates and actionable guidance to accelerate design and review cycles.

Which AUTOSAR versions, formats, and toolchains are supported?

Provide the exact AUTOSAR release (e.g., AUTOSAR 4.2.x Classic, AUTOSAR Adaptive 21.0.0) and Autosar Expert will tailor responses accordingly. Common supported artifacts and formats include ARXML, SWC descriptions, C/C++ code, DBC, YAML/CSV for tables, and textual requirement documents. The assistant produces artifacts compatible with common authoring tools (DaVinci, EB tresos, Vector tools) but does not execute or validate them — you must import and validate generated files in your chosen toolchain.

Can Autosar Expert deliver production-ready or certifiable AUTOSAR code?

No — Autosar Expert can generate high-quality templates, example ARXML fragments, and code skeletons that accelerate development, but generated items are not automatically production-ready nor certifiable. All outputs must be reviewed, validated with official AUTOSAR tools, tested against target hardware, and subjected to your organization’s safety and certification processes (e.g., ISO 26262) before deployment.

How do I use Autosar Expert in my development workflow and CI/CD?

Use Autosar Expert to create repeatable artifacts: standardize ARXML templates, generate unit-test skeletons, produce validation scripts (schema checks), and draft CI job examples (e.g., validation → static analysis → unit tests). Commit AI-generated templates to a repository branch, run your AUTOSAR tool validations in CI, review results, and iterate. Autosar Expert can supply sample CI YAML, validation commands, and test-case descriptions but does not perform builds or run your CI server.

What are the limitations, privacy considerations, and best verification practices?

Limitations: the assistant cannot run AUTOSAR tools, compile code, or access private repositories unless you paste content. It may hallucinate structured details if input context is insufficient. Privacy: avoid pasting proprietary secrets or confidential IP unless permitted; sanitize data when necessary. Verification: always validate ARXML with your authoring tools, run static analysis and tests, and have domain experts review outputs. For highly sensitive or regulated projects, prefer on-premise or approved enterprise deployments and consult legal/MD/QA teams.

Autosar Expert — purpose, capabilities and design intent

Autosar Expert is a specialized AUTOSAR-focused advisory and execution assistant tailored for engineers, architects and project teams working with AUTOSAR Classic and Adaptive platforms. Its design purpose is to accelerate correct AUTOSAR adoption, reduce integration and configuration mistakes, and provide actionable, engineering-grade guidance across architecture, configuration, code-generation workflows, verification and functional-safety alignment. Core responsibilities and behavior: • Explain AUTOSAR building blocks and trade-offs (RTE, BSW modules, SWCs, VFB, ARXML, Classic vs Adaptive). • Produce step-by-step design guidance (partitioning, runnable definition, scheduling, memory budgeting). • Provide configuration patterns and mapping strategies for ARXML and common toolchains (for example: how to structure SWC-to-ECU mapping so it is compatible with common vendors' tools). • Help create verification artefacts: acceptance tests, SIL/HIL test vectors, UDS diagnostic checks, and static-analysis checklists for MISRA/ISO 26262. • Support migration and interoperability tasks (legacy-to-AUTOSAR migration, Classic-to-Adaptive interfacing, SOME/IP service design). Illustrative examples / scenarios: 1) New ECU design (powertrain controller): Autosar Expert helps define SWCs and runnables, suggests an RTE mapping, proposes priority and memory budgets, lists required BSW modules (Autosar Expert introductione.g., CanIf, PduR, Com), and provides a verification checklist for SIL-level integration. The output is a concrete step list the engineering team follows to produce ARXML and configure toolchain artifacts. 2) Migration of legacy controller to AUTOSAR Classic: Autosar Expert analyzes legacy interfaces and suggests SWC decomposition, designs CAN-frame mapping for PDU Router, outlines ARXML fragments and BSW configuration candidates, and recommends test vectors for regression testing on SIL/HIL. 3) Adaptive service design for domain ECU: Autosar Expert prescribes a SOME/IP service definition, describes service discovery and lifecycle behavior (service registration / service instance), suggests security considerations (transport protection, authentication) and gives an example API shape suitable for adaptive apps (C++/ARA conventions) together with a validation plan.

Primary functions provided by Autosar Expert

Architecture & partitioning guidance (Classic and Adaptive)
Example
Designing a vehicle-domain controller where sensor fusion, motion planning and diagnostics run across multiple ECUs: Autosar Expert recommends which functions become SWCs, which need to be on the Adaptive platform (service-oriented, dynamic), and which remain on Classic (real-time control). It proposes runnable grouping, priorities, and minimal communication interfaces.
Scenario
An OEM wants to create a central ‘chassis domain’ controller. Autosar Expert produces a decomposition: low-latency closed-loop controllers as Classic SWCs with time-triggered runnables; higher-level coordination as Adaptive services using SOME/IP; details the VFB interfaces between them; produces a mapping strategy so the RTE generator and Adaptive service layer can interoperate; and provides a scheduling and memory budget estimate to be validated on target hardware.
Configuration, ARXML generation patterns & toolchain integration
Example
For a brake ECU, Autosar Expert provides clear configuration guidance: which BSW modules to enable (e.g., CanIf, CanTp, PduR, Com), how to structure ARXML modules (SoftwareComponentType, RunnableEntities, PortInterfaces), and an integration checklist for popular configuration tools and RTE generators.
Scenario
A Tier-1 configures a new ECU with Vector daVinci / EB tresos / other tools. Autosar Expert supplies recommended ARXML element organization, suggests parameter values for CAN-FD timing and PDU sizes, gives sample mapping rules for SWC ports→PDU, and lists exact steps to import the ARXML into their toolchain, run the RTE generator, and validate generated stubs in a SIL build.
Verification, testing, diagnostics and functional-safety alignment
Example
Create SIL test cases and UDS diagnostic checks for an ECU bootloader and application. Produce fault-injection scenarios, acceptance criteria, and test vectors that exercise ASIL decomposition and watchdog/timeouts.
Scenario
A validation team encounters intermittent communication loss on a CAN bus. Autosar Expert provides a prioritized diagnostic checklist (check CAN driver initialization, CanIf Rx/Tx path, PduR routing configuration, schedule misalignments), recommends UDS routines and negative test vectors, proposes logging points, and supplies a template HIL test script to reproduce and close the defect. For functional safety, it maps system safety goals to software safety requirements and recommends SOTIF/ISO 26262-relevant verification activities and traceability templates.

Target user groups and why they benefit

Embedded software engineers and system architects (OEMs and Tier-1 suppliers)
These are engineers who design ECUs, partition features into SWCs, configure RTE and BSW, and write/validate embedded application code. They benefit from Autosar Expert because it accelerates design decisions (how to decompose features into SWCs, runnables and ports), prevents common configuration mistakes (PDU sizes, misrouted PDUs, mismatched endianness), and provides concrete guidance for toolchain workflows (ARXML organization, RTE generation strategy). The assistant reduces iteration time between architecture, configuration and integration teams and produces repeatable templates, checklists and example artifacts the engineers can use directly.
Functional-safety engineers, test & validation teams, and integration leads
These roles focus on requirements traceability, ISO 26262 compliance, SIL/HIL validation, diagnostics and release readiness. Autosar Expert helps by translating safety goals into software-level constraints, by proposing test cases for ASIL decomposition, by creating test vectors and diagnostic routines (UDS/OBD/DoIP guidance), and by providing integration checklists for HIL setups and CI pipelines. Integration leads receive concrete, prioritized troubleshooting steps for communication, timing and resource issues, which shortens time-to-resolution during system integration phases.

Prepare prerequisites
Collect the project artifacts and context before querying: AUTOSAR release (Classic/Adaptive and exact version), ARXML files or excerpts, SWC descriptions, ECU mapping, target OS/MCU, toolchain names (e.g., DaVinci, EB tresos, Vector), and any error logs or validation reports. Familiarity with AUTOSAR concepts (RTE, BSW, SW-C) and your build environment improves result quality.
Provide focused inputs and requests
Ask precise, scoped questions and supply relevant snippets (ARXML, code, tracebacks). Request the exact output format you need (ARXML fragment, C/C++ skeleton, YAML, mapping table, step-by-step instructions, or test-case templates). State constraints such as safety levels, target ECU resources,How to use Autosar Expert or coding standards to guide output.
Integrate and validate outputs in your toolchain
Treat generated artifacts as templates: import ARXML into your AUTOSAR authoring tool, run static validation, build and execute unit/integration tests, and iterate. Use version control to track generated changes. For CI/CD, convert recommendations into automated validation steps (schema checks, static analysis, unit tests).
Tips for optimal experience
Be explicit about AUTOSAR version and goals, present minimal reproducible examples, request incremental/safe changes, and ask for alternate approaches when needed. Sanitize proprietary data before sharing. Validate all outputs with official AUTOSAR tools and subject-matter experts before production use.
