SimfiaNeo software

Master the Functional Safety of Your Complex Systems

Your systems’ complexity is exploding. Functional safety (RAMS) requirements are stricter than ever. Yet, your traditional analysis tools are struggling to keep up.

Spreadsheet-based FMEA analyses are becoming unmanageable, maintaining traceability is a constant struggle, and the slightest design change forces you to start over—risking costly errors in front of certification auditors.

The MBSA (Model-Based Safety Analysis) approach was developed to break this deadlock. That is precisely what SimfiaNeo delivers.

We designed this RAMS analysis software to fundamentally transform the way you work. Say goodbye to siloed analyses. With SimfiaNeo, you build a central model, a true digital twin of your system dedicated to safety. This dynamic model becomes your single source of truth to automatically generate your analyses (FTA, FMEA), simulate complex scenarios, and justify your design choices.

Developed on the powerful AltaRica language and backed by the field expertise of Airbus Protect engineers, SimfiaNeo empowers you to master risks and accelerate your projects with full confidence.

Key features

• Intuitive Graphical Modeling (AltaRica): Visually describe your systems to reduce interpretation errors and accelerate project reviews.

• Highly Configurable Interface: Adapt the tool to your methodologies and internal processes, not the other way around.

• Library Management: Capitalise on your work by creating reusable component libraries to standardise and speed up future projects.

• MBSE Interoperability (Capella Bridge): Integrate safety into the core of your systems engineering. Ensure perfect consistency between your system architecture and your safety analysis.

Modelling

Validation

• Real-Time Validation: Detect logic errors early, directly within the modeling interface, before even launching calculations.

• Truth Table Verification: Formally validate the behavior of your components for maximum reliability in your analyses.

• Step-by-Step Simulation & Scenario Replay: Understand in detail the sequence of events leading to an undesired situation and communicate your findings more effectively.

Exploitation & Computations

• Automatic FMEA Generation: Save valuable time and ensure the consistency of your analyses by generating your FMEA tables directly from the model.

• Monte Carlo Simulation: Accurately calculate your RAMS metrics (Availability, Reliability, MTBF) to quantify your system's performance.

• Minimal Cut Sets Generation: Automatically identify all failure combinations that lead to a top undesired event.

• Common Cause Analysis (CCA): Verify specific properties on your results to identify critical vulnerabilities within your architecture.

Frequently Asked Questions (FAQ)

What is the main difference compared to a classic FMEA/FTA approach? The difference is the model. With SimfiaNeo, your FMEA and FTA analyses are results generated from a central model, guaranteeing their consistency. In a classic approach, they are separate documents, which are difficult to maintain and keep synchronized.

Is SimfiaNeo only suitable for aerospace? Not at all. While our heritage is in aerospace, SimfiaNeo is a multi-industry tool proven in Defense, Energy, and Transportation. Its flexibility allows it to adapt to the constraints and standards of each sector.

Do I need programming skills to use SimfiaNeo? No. SimfiaNeo is a graphical tool designed for safety engineers and system architects. Modeling is done through an intuitive interface, requiring no specific development skills.
