Functional safety – services under IEC 61508, ISO 62061, ISO 13849, ISO 26262 standards
I provide services that cover activities described in functional safety standards (IEC 61508, ISO 62061, ISO 13849, ISO 26262)
Hazard analysis and risk assessment
Identification of hazards, determination of risk levels and required functional safety levels.
Determination of functional safety level
- Determining required SIL / PL / ASIL levels depending on the application.
- ASIL safety level decomposition
Defining safety requirements
- Development of safety requirements at system, hardware, and software levels.
- Assignment of attributes to safety requirements
- Development of validation and verification criteria for requirements
- Development of requirements traceability report
Functional safety concept design
- Development of general concept
- Development of functional concept
- Development of technical concept
Development of safety system architecture and allocation of safety functions
- Preparation of safety system architecture concept with allocation of safety functions to hardware elements and software components. Assignment of safety requirements for individual software components and hardware
- Evaluation of system structure in terms of fault tolerance and meeting safety requirements.
- Conducting dependent failure analysis
- Reliability and fault tolerance analysis - Calculation of safety parameters such as failure probability and diagnostic coverage.
Failure and failure mode analysis
- Identification of potential failures and their impact on safety function implementation.
- Verification of the effectiveness of applied safety mechanisms.
Comprehensive support
- Support in hardware development - hardware evaluation in terms of functional safety requirements
- Support in software development:
- Analysis and evaluation of the process and implementation of safety function software.
- Conducting safety analysis (FTA, FMEA) of individual software functions
- Analysis of defects detected in the testing phase and development of safety-critical corrective actions
- Process evaluation - Verification of design, implementation, and testing processes for compliance with standard requirements.
- Support in certification and conformity assessment process
