Shulou(Shulou.com)06/03 Report--

With the development of new technologies such as intelligent driving and new energy, the functional safety of automobile electronic and electrical systems has been paid more and more attention. During the implementation of the international functional safety standard ISO 26262, many thorny problems were encountered: how to implement HARA correctly and effectively to achieve appropriate safety objectives? How can security analysis be performed to ensure that security requirements are complete and adequate? How do I verify the security of my system/software/hardware design? How to evaluate and calculate hardware indicators? How to ensure traceability, consistency and integrity of the development process?

function introduction

medini analyze tool is a professional functional safety development platform tool, which conforms to the whole process of ISO 26262 development. Its functions cover all development activities required by ISO 26262. Its main functions are as follows:

refer to ISO26262 2018

·Project definition

Support function definition, behavior design, initial architecture modeling;

♦ HAZOP templates are provided for failure identification, etc.

·Hazard analysis and risk assessment

Provide a driving scenario database to support HARA scenario analysis;

♦ Standard HARA templates are provided to make HARA analysis process clearer and simpler.

·Security requirements development

Provide semi-formal requirements templates that meet ISO 26262 requirements to ensure the standardization and integrity of requirements writing;

♦ Support safety requirement derivation based on safety analysis (such as FTA) to ensure that safety requirements are not missed;

♦ Support the creation of UML requirements tree, meet the visual requirements traceability relationship establishment and maintenance;

Supports interaction with mainstream requirements management tools such as DOORS, DNG, PTC, etc.·Security architecture design

♦ Support standard SysML language architecture design, support the allocation of requirements to the architecture, and achieve traceability of requirements and design;

♦ Support import of output model files from Simulink, SCADE, EA, Rhapsody and other mainstream modeling software.

·Safety Analysis FMEA

♦ Support FMEA table generation based on SysML design model, ensure the direct relevance and integrity of FMEA and its analysis object (architecture), and facilitate updating FMEA when optimizing architecture;

♦ Support the creation and management of prevention/detection measures, integrating all safety mechanisms of ISO26262 part5 appendix D.

·Safety analysis FTA

♦ Support the creation of FTA based on SysML design model, ensure the direct correlation between FTA and its analysis object (architecture), and facilitate the mutual verification with FMEA;

♦ Support qualitative FTA analysis such as minimum cut set and importance, and calculation of quantitative FTA (PMHF).

·Hardware metrics calculation FMEDA

♦ 5 failure rate calculation manuals including SN29500, IEC62380, and IEC 61709 newly recommended by ISO 26262:2018;

♦ Support automatic generation of FMEDA tables recommended by ISO 26262 based on Excel/CSV format BOM.

·Strong traceability

♦ Support the creation of traceability relationships for any element within the project, such as requirements association relationships at different levels, allocation relationships between requirements and design architecture, and corresponding relationships between architecture and security analysis verification;

♦ Support visualization of functional and architectural dependencies;

♦ Support visual traceability relationship display such as Function net and Failure net.

Applications & Cases

GM--Functional Safety Analysis of Lane Keeping Assistance System

The main reasons for GM to choose medini analyze are: supporting the whole process of ISO 26262 functional safety development, ensuring the consistency of the development process, compatible and integrated with GM's original tools to form a complete tool chain, automatically generating standard ISO 26262 work reports, and greatly improving the efficiency of GM lane keeping assistance system functional safety analysis.

Mobileye--Analysis of safety strategies for autonomous driving

Mobileye takes medini analysis as the core tool of its automatic driving safety strategy development, divides the automatic driving safety goal into functional safety ISO26262 safety goal and expected functional safety SOTIF safety goal, systematically decouples the association relationship between functional safety and expected functional safety, not only realizes the functional safety development of products, but also actively explores the implementation process of SOTIF with medini analysis.

Medini analyze is working on ISO 26262 security and SOTIF, cybersecurity and other features. A new version supporting SOTIF and cybersecurity will be released soon. Stay tuned!
