paitron – Functional Safety Suite

Safety analyses via simple drag & drop

Automate safety analyses

Our solution reuses existing digital models from standard modeling & simulation environments. This avoids additional training & modeling effort, while enabling a continuous & integrated workflow.


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.

ISO 26262

Originated 2011 as functional safety standard for the automtive industry. Latest revision 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 mandatory.

Whether medical devices, marine systems, trains or in aerospace, functional safety analyses are prescribed globally.



Matlab Simulink

The modeling and simulation tool for nearly all use cases. With libraries ranging from the hydraulic to the electronic domain, Matlab Simulink is used across industries. Matlab Simulink 2019a onwards are supported. 


Freeware tool by Analog Devices is the go-to software to simulate electronic circuits. Features are modeling, simulation & generation of Bill-of-materials. The latest version LTspice XVII is supported. 

OrCAD PSpice & Capture

Developed by Cadence, Orcad offers functionality from modeling, simulation to layouting.

FMEA is an inductive approach to assess a system’s behavior under fault. The bottom-up analysis allows to inspect possible failure modes methodologically.  


Failure modes, effects, and criticality analysis puts emphasis on the severity and occurence rate of failure effects. 


Failure modes, effects, and diagnostic analysis is an extension to the FMEA to reflect diagnostic capabilities of a system.
