Join us at the first AESIN ADAS & AV Seminar on 6 December 2017 (University of Warwick, UK)


The first AESIN ADAS (Advanced Driver Assistance Systems) & AV (Autonomous Vehicle) Seminar will be hosted by by WMG at the University of Warwick on 6 December 2017.

This one-day seminar will provide an opportunity to explore the enabling electronic system technology for next generation ADAS & AV designs. The presentations will cover the ADAS & AV spectrum and include sensing, control, system modelling – and safety.

At this event, Dr Michael J. Pont (Executive Director at SafeTTy Systems Ltd) will give a presentation entitled: “Improving confidence in the safety of ADAS / AV designs that incorporate ‘unqualified’ software or hardware components”.

In this presentation, Michael will consider the challenges that are presented by the use of ‘unqualified’ software or hardware components in safety-related ADAS / AV designs. Such components – sometimes called ‘SOUP’ (‘Software of Unknown Provenance’) or ‘HOUP’ (Hardware of Unknown Provenance) – include off-the-shelf software libraries or microcontrollers that were not developed in compliance with the ISO 26262 international safety standard. In the presentation, Michael will demonstrate how use of a simple ‘TT Wrapper’ can significantly improve confidence in the safety of such designs.

Introducing our first DuplicaTTor® Design Suite (DDS-0405)


Our first DuplicaTTor® Design Suite – DDS-0405 – is intended to facilitate the development of industrial / generic designs in compliance with IEC 61508 (at ‘SIL 3’); machinery designs in compliance with ISO 13849 (at ‘Pl e’); household goods in compliance with IEC 60730 / IEC 60335 (at ‘Class C’); medical equipment in compliance with IEC 62304 (at ‘Class C’); and automotive designs in compliance with ISO 26262 (at ‘ASIL D’).

DDS-0405 can also be used to prototype civil aircraft designs in compliance with DO-178C (up to ‘DAL A’).

Further information can be found on the DDS-0405 page.

[1] The DuplicaTTor family is primarily intended as an effective foundation for ‘SIL 3’ and equivalent designs developed in compliance with a range of international safety standards.

[2] When developing ‘SIL 4’ and equivalent designs, an heterogeneous hardware platform may be required (using two different MCUs). In these circumstances the DuplicaTTor family can be employed as an effective prototyping platform (and we can provide a custom hardware platform for your product: please refer to the DEB-0405 page for further details).

[3] Use of the DuplicaTTor family is not recommended for ‘SIL 0’ (and equivalent) designs: please refer to ‘ERES2‘ for alternative design solutions.

[4] The DuplicaTTor family can be applied when developing ‘SIL 1’ / ‘SIL 2’ (and equivalent) designs but is not usually necessary: please consider a CorrelaTTor platform (presented in ‘ERES2‘) as a cost-effective alternative.

About to develop your first safety-related embedded system?


In our experience, the main challenge facing organisations developing their first safety-related embedded system is that they underestimate the work required to achieve compliance with the relevant international standards (including support for comprehensive test & verification processes, the creation of suitable paperwork, and the need to support ‘paper trails’).

If the additional load imposed by the need to meet safety requirements is not taken into account, this can result in significant project delays, increased costs, a stressed and demoralised team, staff changes – and further expensive delays …

To avoid such problems, it is important to be clear about the likely project timescales and costs up front, and to employ an appropriate way of engineering the system (so as to simplify the processes of test & verification, the creation of paperwork, and the certification process itself).

Through use of a SafeTTy Solutions package, we can introduce your team to an industry-proven approach to the development of safety-related embedded systems. We can then work with your team as they go through the key stages of creating their first product.

The end result of applying a SafeTTy Solution package is likely to be a smoother, faster and cheaper development process – and retention of a well-trained and experienced team that is looking forward to embarking on their next safety-related project.

Cost-effective ‘TT’ software training for individuals and small teams


Completing our popular TTb course is of particular benefit to organisations that need to develop software in compliance with ISO 26262, IEC 61508 and related international safety standards.

Since 2014, we’ve delivered TTb ‘on-site’ to many organisations across the world: so far, we’ve introduced around 150 engineers to the use of TT software architectures in safety-related systems by means of this 3-day course, with a class size of around 6 being typical.

We appreciate that for individuals and small teams, on-site training can be a little expensive. We also appreciate that it can be difficult for any organisation to have their whole development team attend a training course at the same time.

To address these challenges, we’ve introduced an online version of our TTb course. At a cost of approximately £150 / US $200 per person for two months of part-time training, we hope that this flexible new option will allow many more engineers to gain the skills needed to develop effective TT software.

Learn more – and watch a ‘course trailer’ – on our TTb page.

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).

Need help with your ISO 26262 project? Learn more on our Consultancy page – or contact us to discuss your requirements.

The SafeTTy Summer School is back – and this time we’re going on tour!


In 2014 and 2015 we ran a successful ‘Summer School’ programme in the UK.

We took a break from this programme in 2016 (in the run up to the publication of ‘ERES2‘), but this year the Summer School is back. This time, we’re heading off on a European tour, running from July to September 2017.

The SafeTTy Summer Tour 2017 is aimed at organisations that need to develop software for safe and reliable embedded systems in compliance with international standards such as ISO 26262 and IEC 61508.

In most cases, the SafeTTy Summer Tour 2017 will involve one-day training sessions on company sites across the EU. During these sessions, we’ll provide four hours of introductory training on TT architectures. To help you get the most out of your event, we’ll also provide books, printed course notes, DuplicaTTor Evaluation Boards (with detailed code examples) and 12-month ReliabiliTTy evaluation licences for every host organisation.

Where required, we can extend the visits by two days: in these circumstances, we’ll cover the whole TTb training course.

Assuming training for six people (and including a DuplicaTTor board, course notes and book for each participant), fees for a 1-day Summer School visit are £5000 + VAT. Fees for a 3-day Summer School visit (again with all materials for up to 6 people) are £8000 + VAT. Outside the UK, an additional fee of £500 per course will be added to offset flight and accommodation costs. Both course fees quoted include the cost of a 12-month ReliabiliTTy evaluation licence.

We can adapt the programme to meet your requirements (including support for larger class sizes).

Join us at Safety-critical Systems Symposium 2017 (SSS’17) in Bristol (UK)

scsc_tag_120
Safety is increasingly important with autonomous, distributed, highly inter-connected systems all around us, taking over many functions previously done by humans. The world of driverless vehicles, remotely controlled home systems and delivery by drone is happening now.

The Safety-Critical Systems Club has operated in support the safety community since 1991. Each year, in early February, the Club’s annual symposium has been held.

Please join us at the ‘Silver Jubilee’ SSS event from Tuesday 7 – Thursday 9 February, 2017 in Bristol UK.

At SSS 2017, Dr Michael J. Pont (Executive Director, SafeTTy Systems Ltd) will give a presentation entitled:
Going ‘Back to the Future’: Developing safety-critical embedded systems using modern Time-Triggered software architectures“.

Presentation abstract:

This paper is concerned with the development of software for real-time, safety-related embedded systems. The particular focus of the paper is on ‘Time-Triggered’ (TT) systems. TT design can be viewed as a subset of more generic ‘Event Triggered’ (ET) designs. When compared with ET alternatives, TT designs have a simple software architecture and – once constructed – are generally accepted as being easier to test. As a consequence, forms of TT design have been used for many years in industries such as aerospace, because they have been found to provide the basis for safe and reliable systems. Despite the growing demand for safety-related embedded systems in sectors such as industrial control, automotive and household goods, use of TT architectures is less common than ET architectures in these areas. This paper explores some of the benefits of modern TT designs, and considers some of the reasons why this approach is less commonly used than ET architectures in current safety-related designs.

Further information about SSS 2017 can be found here.

Join us at the ISO 26262 Workshop on 26 January 2017 (Nuneaton, UK)


The next NMI ISO 26262 Workshop will take place at HORIBA MIRA (Nuneaton, UK) on 26 January 2017:

The automotive industry is going through a period of unprecedented change as embedded systems enable greener and safer vehicles.

Manufacturers facing the challenge of increasing system complexity are required to meet the stringent safety requirements defined in the international standard ISO 26262.

This workshop will provide the latest update on the Standard from HORIBA MIRA expert Dr David Ward, and a range of industry talks covering key current challenges including security, automated vehicles and lessons from other sectors.

Don’t miss this exclusive opportunity to hear the latest from industry experts and peers working with the ISO 26262 standard.

Please join us at this event, where Dr Michael J. Pont (Executive Director, SafeTTy Systems Ltd) will give a presentation entitled: “Are there lessons that ISO 26262 developers can (and should) learn from IEC 61508?

Presentation abstract:

This presentation will be concerned with the development of software for real-time automotive systems that need to be both safe and reliable.

The goal of the presentation is to explore one of the central differences between ISO 26262 and IEC 61508, and to consider whether there are lessons that can (and perhaps should) be learned from the earlier (generic / industrial) safety standard by developers of automotive systems.

During the talk it will be suggested that one key difference between IEC 61508 and ISO 26262 is that the latter standard places less (explicit) reliance on the idea of fault tolerance. In particular, the phrase ‘Hardware Fault Tolerance’ (which is referred to throughout IEC 61508) does not appear in ISO 26262. One important consequence of this difference is that, while IEC 61508 can be seen to favour use of multi-processor architectures, there is much less emphasis on such a solution in ISO 26262.

Does this mean that ISO 26262 designs are likely to be ‘less safe’ than equivalent IEC 61508 designs?

It is hoped that this presentation will encourage a debate at the workshop.

At this event, you’ll have the opportunity to take a look at the recently-published ‘ERES2‘ book – and our much-anticipated new family of DuplicaTTor® Boards.

You’ll find further information about this event on the NMI website.
