Safety Architect

Automatically generate the fault trees for your complex systems

Safety Architect is a tool achieving risk analysis of complex systems using functional or physical architectures from usual modeling tools, for example SysML or UML based tools. From a functional or physical definition of the system, Safety Architect allows to perform a kind of local FMECA and automatically deducts the FTA corresponding to the identified feared events.


Compliant with all the engineering loops
Focus on added value tasks
Enlighten the critical components and flows
Integrate safety analysis and design of your systems
Reduce the analysis cost and decrease the risk of errors
Capitalise on your analysis results for further iterations

Create or import models

Import data from your existing models to start easily your safety analysis, or create a new project from scratch directly in our tool. The projects created from usual modelisation tools like MagicDraw, Rhapsody, Scade System or Papyrus can be natively imported. A tighter integration is also available for Rational System Architect (RSA) and Capella, to allow especially to re-export the data from the safety viewpoint, including the resulting fault trees, to enrich your system representation.

Graphical analysis

Create the graphical representation of your system or reuse the representation of your imported model. Safety analysis can then be performed locally to each block of your system, using a dedicated graphical representation, corresponding to the block dysfunctional behavior, and particularly considers the safety barriers or the block failure effects.

Automatic global propagation

Launch an automatic and global propagation of the failures in your system. Using the feared events which are identified and located on your system outputs, and the local analysis of each block, this step consists in spreading in the system all the identified failure modes, to trace those (or combinations of them) that reach a feared event and generate automatically the related fault trees. Moreover, if the probabilities have been set on the failure modes or events, they are preserved in the fault trees, to be exploited in dedicated tools after an export.

Reports and fault trees export

The generated fault trees can be exported to dedicated tools, as FaultTree+ or to any tool able to read OpenPSA format, like ArbreAnalyste. Moreover, all the data of your model can be used to create a report, which can be saved as a Word, a PDF or HTML file, to archived or share.

Full Capella integration

A bridge can be installed in Capella and Safety Architect to ensure a full integration of the both softwares. This will add a safety viewpoint in Capella and allow to navigate from one software to the other dynamically. For instance, from a Capella function open the corresponding local analysis in Safety Architect, and once that you have generated a fault tree in Safety Architect, display the corresponding critical chain in Capella.

They believe in Safety Architect

Safety Architect has been used for several projects in various domains, such as defense, energy, transport and medicine. Try our tool for free and be the next to automate your safety analysis.

Safety Architect Naval Group

DCNS réalise la plupart de ses analyses de risques des Systèmes de Combat avec Safety Architect. Il est utilisé depuis 2010 et DCNS a pris l'habitude de travailler avec sur les études Systèmes de combat. C'est un outil plus convivial que Excel pour la réalisation d'AMDE. Les points forts de l'outil ?

  • Interfaçage avec des outils de modélisation
  • Gain de temps sur les reprises des analyses
  • Convivialité
Romain PALUD, Ingénieur Safety NAVAL GROUP

Safety Architect Thales

The assets of Safety Architect are the following: a tool easy to take in hand, an understandable methodology, and readable models. Our ambition today is to extend the tool interface with MBSE practices in order to coordinate these approaches.
