Medini analyze R & D, headquartered in Berlin, Germany, is a subsidiary of ANSYS in the United States, and has been committed to providing users with security analysis and design as well as embedded software system solutions for many years. Its products mainly include:

Functional Security Development tool of medini analyze- conforming to ISO26262 Standard

Tools for comparing and merging mediniunite-Simulink, Stateflow and TargetLink models

Since the release of the automotive functional safety standard ISO26262 in November 2011, functional safety has aroused widespread concern in the global automotive industry. At present, the technical development strength of functional security of domestic mainframe factories and most suppliers still can not meet the requirements of ISO26262 standard. Medini functional security tools can assist customers to carry out functional security projects and improve customer security development process, thus greatly enhancing the technical development strength of customers in the field of functional security.

Product introduction

Functional Security platform tool of medini analyze- conforming to ISO26262 Standard

Medini analyze is a professional tool for functional security development platform, which supports the whole process of functional security development in accordance with ISO26262 standards. Its main functions include:

♦ project definition: relevance definition, function definition, failure identification, initial frame modeling, etc.

♦ HARA analysis: hazard analysis and risk assessment, ASIL level determination, safety target analysis

♦ requirements management: supporting chart editing of security goals and requirements, mapping of requirements to architecture and functions, requirements import and export

♦ system modeling (SysML): specification failure mode, failure rate, allocation and visualization of ASIL levels

♦ functional modeling: Simulink/Stateflow model import, association, automatic creation of FTA model

♦ failure Mode and impact Analysis (FMEA): components and functions can be automatically imported into standard FMEA/FMEDA tables, and RPN can be calculated automatically

♦ hardware index calculation: single point failure index SPFM, potential failure index LFM, security mechanism design

Reliability prediction model of ♦ integration: integrating SN29500, MILHDBK217F and IEC62380, the failure rate parameters of related devices can be selected directly.

♦ fault tree (FTA): qualitative analysis (cut-sets evaluation), quantitative calculation (PMHF calculation)

♦ 's mature tracking function: establishing a tracking relationship for any element within the project

♦ integrated task management function

♦ tool integration: has a good integration interface with IBM's DOORS/ Rhapsody/ RTC, EA, MATLAB/ Simulink and other tools

Tools for comparing and merging mediniunite-Simulink, Stateflow and TargetLink models

The main functions of the model-based comparison and merge tool are as follows:

♦ can compare Simulink, Stateflow and TargetLink models.

♦ supports automatic or manual target model merging

♦ details the differences between MATLAB/Simulink or Stateflow models

♦ supports team division and cooperation and conflict detection during collaboration, and supports the operation of "undo/redo" in the merger process.

♦ integrated version management function

Application & case

Functional Safety Analysis of GM- Lane maintenance Auxiliary system

The main reasons why GM chooses medini analyze are: to support the whole process of ISO26262 functional safety development, to ensure the consistency of the development process, to be compatible with and integrate the original GM tools to form a complete tool chain, and to automatically generate standard ISO26262 work reports. Greatly improve the efficiency of functional safety analysis of the GM lane maintenance auxiliary system.

Magna- establishes the functional safety development process of new energy vehicles

New energy is a new field, and it is necessary to introduce a functional security development process in line with the ISO26262 standard on the basis of the original development process. It is necessary to adopt standard functional safety analysis methods and work product templates, and at the same time, we need to consider the unique safety attributes of electric vehicles, and assist Magna to develop standard development processes and work product templates to form standardized work products.
