SafeTTy Systems Ltd
From our base in the UK Midlands, we provide support for organisations across the world that need to create real-time embedded systems that are safe, reliable and secure.
Many of our customers need to achieve compliance with ISO 26262, IEC 61508 and related international safety standards and guidelines. We help them to meet these requirements through the use of state-of-the-art “Time-Triggered” (TT) software architectures.
- a comprehensive and cost-effective consultancy service, delivered by Dr Michael J. Pont;
- internationally-recognised training and certification programmes for developers of safety-related embedded systems;
- a series of popular books on TT systems and functional safety, including the recently-published ‘ERES2‘;
- advanced DuplicaTTor® boards and related code examples that allow rapid design evaluation;
- introductory Taster Days that explore the benefits of TT systems (delivered on your company site);
- complete SafeTTy Solutions™ packages, including consultancy plus training and technology licences.
Examples of current ISO 26262 projects
At present, we are helping many of our customers to develop automotive systems in compliance with ISO 26262.
For example, we can assist in the development of ‘Safety Elements out of Context‘ (SEooCs). These are ‘components’ (such as a sensor or a software library) that will ultimately be used as part of a larger vehicle system.
In such projects, our role might include: [i] performing an ISO 26262 ‘gap analysis’; [ii] providing design advice and / or training; [iii] assisting with the process of obtaining an ‘ISO 26262 SEooC certificate’ from a third-party organisation (such as TÜV); [iv] assisting with the creation of the Safety Manual.
A particular focus of our current work is on SEooCs for use in semi-autonomous / autonomous vehicles (up to SAE Level 4 / Level 5).
You’ll find an ISO 26262 (ASIL D) design example here.
You’ll find an article that summarises some of the ways in which a ‘TT wrapper’ can be used to improve confidence in the safety of Level 3 / Level 4 / Level 5 road vehicles (developed in compliance with ISO 26262) here.
Our popular ‘ERES2’ book is now available as a paperback
The popular ERES2 book documents an industry-proven approach to the development of software for reliable, real-time embedded systems, based on the use of ‘Time Triggered’ (TT) architectures.
The case studies in ERES2 describe the development of software for the following products: [i] an industrial alarm sounder unit (IEC 61508, SIL 2); [ii] a domestic washing machine (IEC 60730, Class B); [iii] a hospital radiotherapy machine (IEC 60601-1; IEC 62304, Class C); [iv] a steering-column lock for a passenger car (ISO 26262, ASIL D); and [v] an aircraft jet engine (DO-178C, Level A).
You’ll find further information on the ERES2 page.
