Functional Safety related services

Ansys medini® analyze supports analysis of functional safety of electronic and software-based systems. Originally developed to support the automotive ISO 26262 standard, it is also applicable in other application domains, for example, in the aerospace domain to support safety analysis according to SAE ARP4754 A and SAE ARP4761 or the industrial domain based on IEC 61508. It combines commonly used analysis techniques for functional safety analysis in one integrated tool environment:

  • Hazard Analysis and Risk Assessment (HARA)
  • Functional Hazard Analysis and Preliminary Hazard Analysis (FHA, PHA)
  • Failure Mode and Effects Analysis (FMEA)
  • Fault Tree Analysis (FTA)
  • Hazard and Operability Analysis (HAZOP)
  • Failure Mode, Effects, and Diagnostics Analysis (FMEDA)
  • Diagnostic Coverage Metrics for HW-Safety analysis
  • Dependent Failure Analysis (DFA)
  • Safety of the Intended Functionality (SOTIF)

By that it supports functional safety (FuSa) related activities during the complete development lifecycle. Medini analyze is a model-based tool and its safety analysis techniques operate on a set of models. The SysML model is the main model on which the safety analyses are based. It is used on various levels of abstraction, from initial functional architectures to detailed technical hardware and software architectures even down to the analysis of semiconductor components. In addition, medini analyze enables requirements and goal modeling to support the provision of functional and technical safety concepts. With the 2020 R1 release, medini analyze extended its scope into cybersecurity threat analysis and risk assessment.

Ansys SCADE Architect is a system design product line for complex embedded systems modeling, based on the standard SysML notation, including:
