Paitron– Functional Safety Suite
Automated functional safety analysis via drag & drop
Automate with Paitron
Paitron acts as a spell checker for engineering models, offering a “one-click” approach for safety analysis. Unlike other solutions, it seamlessly integrates with your preferred simulation tools, such as OrCAD & Matlab Simulink, reusing existing digital models for FMEA, FMECA, and FMEDA.
This streamlined process significantly reduces modeling overhead, eliminates the need for additional test models, and ensures a seamless, efficient, and hassle-free workflow with no media break.
Trustworthiness
No magic, nor probabilistic methods are used to derive the results. Formal methods and theorem proofing enable white-box reasoning and the highest quality. Therefore, receiving a Concept Report by TÜV SÜD (for ISO 26262 and IEC 61508).
Generic Approach
Whether E/E, PL, or interdisciplinary systems covering mechanics, hydraulics, and pneumatics, Paitron will support you.
Quick Specs
Relevant for
Standards
ISO 26262
Originated in 2011 as a functional safety standard for the automotive industry. The latest revision is in 2018. Distinguishes critical systems along ASIL A-D. Mandatory FMEA/FMEDA.
IEC 61508
The “mother of” functional safety standards was published in 1998. With its latest revision in 2010, it is mainly applied in the process industry. Categories are SIL 1-4. Mandatory FMEDA.
ISO 13849
Published in 2015, ISO 13849 is specifically applicable to control systems of safety-related systems, e.g. in robotics. Provides five classes to determine the safety of a system, PL a-e. FMEA/FMEDA/FMECA is mandatory.

Capable of
Analyses
FMEA
FMEA is an inductive approach to assess a system’s behavior under fault. The bottom-up analysis allows inspecting possible failure modes methodologically.
FMEDA
Failure modes, effects, and diagnostic analysis is an extension to the FMEA to reflect the diagnostic capabilities of a system.
FMECA
Failure modes, effects, and criticality analysis put emphasis on the severity and occurrence rate of failure effects.
and many more...
Furthermore, Fault-tree analysis (FTA), Root-cause analysis (RCA), and many more analyses are employed in the industry. In case of an individualized analysis, please contact us for support.

Reflections on SSS’25: Rethinking Safety in a Complex World
The TLDR: Too busy to read? Here's a quick summary of articleModern electronics are growing ever more complex—with systems now deeply interconnected—yet traditional safety analyses like FMEDA remain manual and outdated. This gap is stark when compared to the...
Template-based formalization of safety functions and analyses
In this article, we present a template for gathering & structuring all information required by a human or software to perform a failure-mode-and-effects analysis (FMEA) using formal languages. The practical use of such a template for safety analysis is highlighted through the safety analysis (single point of failure) of a voltage monitor presented in the “ARP4761 recommended practice for aerospace system safety assessment”.
