Safety Architect

Tools up

your safety analysis

Safety Architect allows the risk analysis of complex systems by automatically generating FMEA and corresponding fault trees from their functional or physical architecture.

The advantages of Safety Architect

Graphical propagation of failure modes

Graphical modeling of software or hardware architecture with function allocations and failure conditions.

Generation of fault trees and FMEA tables

Component fault tree modeling and automatic generation of global system fault trees. Failure modes and effects analysis including critically and diagnostic analysis (FMEA / FMECA / FMDA).

Customization by business domain

Customized editors by business domains (FHA according to ARP4761 or HARA according to ISO 26262-3).

Interfaces with modelers and fault tree tools

Seamless connection to requirement management, system modeling and quantitative fault tree analysis tools.

Reports & metrics

Adaptable reporting and metrics. Exports to many document formats, such as Word, Excel, PDF, and HTML.

Safety Architect Capabilities

Safety concepts modeling

  • Graphical modeling of software and hardware architecture with function allocations
  • Manual component fault tree modeling and automatic generation of the whole system fault tree
  • Integrated failure modes and effects [critically] [diagnostic] analysis: FMEA / FMECA / FMEDA based on Architecture model
  • Automatic synchronization of failure mode and failure data from architecture model to FTA and FMEA/FMECA
  • Customized editor for Functional Hazard Assessment (FHA) according to SAE ARP 4761
  • Customized editor for Hazard Analysis and Risk Assessment (HARA) according to ISO 26262-3
  • ReqIF support for requirements management with the link to FHA, HARA, and architecture elements
  • Allocation of requirements to system architecture, hardware and software and function models

Versions management, differences and merge operations

  • Manage (create, display, restore and delete) the different versions of a project
  • Display the differences between two versions
  • Select some differences to merge to the current version or the target version

Dashboard and metrics

  • Manage globally the content of your model, displaying key information on blocks, events, failure modes, gates and barriers
  • Monitor the evolution of your analysis in real time through dedicated metrics
  • Visualize the progress of local analyses on your blocks, number of analysed and not yet analysed blocks

Integration into MBSE or PLM environment

  • Import your existing models to ease the start of your safety analyses
  • Systems models using SysML standard based tools such as MagicDraw, Rhapsody or Papyrus are directly importable
  • Stronger integration is also available for Rational System Architect (RSA) and Capella, allowing safety data to be re-exported to enhance system representation

Activity explorer and process adaptation

  • Generic activity explorer for safety analysis activities, such as hazard analysis, failure mode analysis, FMEA and FTA
  • Adaptation of the tool data model and editors for the safety analysis process of business domains

Reporting and documentation

  • Adaptable reporting and exports to many document formats, such as Word, Excel, PDF, and HML
  • Import your dedicated tabular reports, such as Excel or CSV files, to a dedicated and customized editors of Safety Architect

Full integration with Capella

Safety Architect - Bridge Capella

Automatic synchronization and data exchange

  • Define your safety scope in a dedicated viewpoint in Capella
  • Transfer your data to a Safety Architect model and navigate from one tool to another easily
  • Take advantage of the power of Safety Architect to perform your safety analyses, generate your fault trees, etc.
  • Reimport the analysis results into Capella to visualize your critical chains in the initial model


Naval Group carries out most of its risk analyses of combat systems with Safety Architect.
It has been in use since 2010 and Naval group is used to work with it.
The strengths of the tool? Its interfaces with modeling tools,
the time saved on analysis rework and its ease of use.
