SafeTTy Systems™


At SafeTTy Systems, we help our customers to develop software for reliable space-based systems, automotive systems (including autonomous vehicles), industrial control systems, medical systems, railway systems, sports equipment …

We do this using an industry-proven engineering process that integrates ‘Time-Triggered‘ (TT) software architectures with patented run-time monitoring techniques.

The designs that we support are typically based on low-cost, off-the-shelf microcontrollers, provided by a range of different semiconductor manufacturers (our technology is not tied to any particular hardware platform).

Where required, we help our customers to achieve compliance with one or more international safety standards: ISO 26262, IEC 61508, ISO 13849, IEC 62304, IEC 60730 …

We offer:

We are a UK company with a worldwide customer base.

BSI PAS 1880: Guidelines for developing and assessing control systems for automated vehicles

empty_space
Dr Michael J. Pont (CEO, SafeTTy Systems Ltd) has been asked to write the first comprehensive set of UK guidelines for developers of automated vehicles. Produced by BSI, this ‘Publically Available Specification’ (PAS) is entitled ‘Guidelines for developing and assessing control systems for automated vehicles’.

Dr Pont comments: “I am very pleased to have been asked to contribute to this important project. The work that I am doing builds on a series of AESIN workshops that SafeTTy Systems helped to organise in 2017-2018 and to which many UK and international automotive companies contributed.”

Dr Pont adds: “The work on this PAS is progressing well, and a draft will be released for public consultation later this year. When complete, the final document will be freely available from the BSI website.”

Latest awards on the SafeTTy Certified™ programme in Mumbai

empty_space
Microdevice Technologies operate as our Training Partner in Mumbai (India).

In 2017, Microdevice Technologies began working in collaboration with Sardar Patel Institute of Technology (SPIT) to deliver courses on ‘Time Triggered’ (TT) embedded systems in Mumbai as part of the SafeTTy Certified programme.

The latest cohort of students completed their ‘Level 1’ examinations on this programme recently.

The photograph shows the successful students receiving their certificates on 14 May 2019, accompanied – on the left – by Govind Gaundalkar (from Microdevice Technologies).

Developing safety-critical systems in compliance with ISO 13849 and IEC 61508 / ISO 26262

empty_space
We receive many enquiries from organisations that need to develop embedded systems in compliance with international safety standard ISO 13849.

  • To achieve compliance with ISO 13849, we have experience developing a range of dual-processor designs: our DuplicaTTor® Design Suite and related DuplicaTTor® Evaluation Board provide a highly-effective platform for such products.
  • ISO 13849 is often used in combination with other (perhaps more familiar) standards. For example, many industrial control / machinery designs need to be developed in compliance with ISO 13849 and IEC 61508. Similarly, ISO 13849 is often used in combination with ISO 26262 when developing various autonomous and / or off-road vehicles.

As an example of the type of design solution that we use in such products, we have prepared an example of a monitoring system for a piece of machinery. In this example, our solution is based on a ‘Time Triggered‘ (TT) software architecture and two low-cost microcontrollers.

The figure below summarises the design solution.

Our popular ‘ERES2’ book is available as a paperback for just £45

ERES2 front cover
Did you know that ‘The Engineering of Reliable Embedded Systems’ (ERES2) is available in a low-cost paperback format?

This popular 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.

Our ‘ERES2’ book is accompanied by a growing suite of public ‘Time-Triggered Reference Designs’ (TTRDs).

Used in conjunction with the book, these code examples are designed to illustrate ways in which TT software architectures can be used to support the development of a wide range of embedded systems for which safety is a key design consideration.

The latest suite of public TTRDs can be downloaded from our TTRD page.
