paitron – Functional Safety Suite
Automated failure analysis via simple drag & drop
Automate safety analyses
paitron acts as a spell checker for engineering models, providing a “one-click” approach for safety assessment. It can be used to conduct FMEA, FMECA, FMEDA & unlike other solutions, paitron reuses already existing digital models from standard modeling environments like OrCAD & Matlab Simulink.
Thus, the overhead for modeling decreases significantly as no additional test model is required, while enabling a continuous & seamlessly integrated workflow!
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.

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.

Whether medical devices, marine systems, trains, or aerospace, functional safety analyses are prescribed globally.
WORKABLE WITH
Interfaces
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 is supported.
LTSpice
The 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.
Cadence
Developed by Cadence, OrCAD offers functionality from modeling, and simulation to layouts.
and many more...
Altium Designer, Mentor Graphics DxDesigner, and many more tools are supported by paitron. In case of no existing interface to your tool, we are happy to provide you with the proper implementation.
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.
FMECA
Failure modes, effects, and criticality analysis put emphasis on the severity and occurrence rate of failure effects.
FMEDA
Failure modes, effects, and diagnostic analysis is an extension to the FMEA to reflect the diagnostic capabilities of a system.
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.

OUR SUCCESS STORIES
What’s happening?
Automatic assessment of an industrial safety-critical system
The HIMax is an industrial safety-critical system of the HIMA Paul Hildebrandt GmbH that contains multiple digital output modules, whose signals are intended for use in a programmable electronic system. In this article, a partial safety analysis of the HIMax is assessed with paitron.
modelwise achieves TÜV concept report
This article aims to show how the tool concept of paitron was evaluated from TÜV SÜD and regarding its certification ability as a qualified software for the use in safety-critical applications.
Where did ARP 4761 go wrong?
In this article, we compare a manually generated expert failure modes and effects analysis (FMEA) taken from SAE ARP4761 with an automatically generated one, produced with paitron and find where the ARP 4761 went wrong.
