Examples of ‘Time Triggered’ projects
At SafeTTy Systems, we help our customers develop software for embedded systems that are reliable, secure and safe – and in compliance (where required) with one or more international safety standards (IEC 61508, ISO 26262, DO-178C, IEC 62304, IEC 60730 …).
We do this using ‘Time-Triggered‘ (TT) software architectures that incorporate patented run-time monitoring techniques.
You can learn more about TT architectures on our Technology page.
On this page we provide links to a set of example designs that illustrate the types of project that we have developed successfully using TT architectures.
If you have any questions about the designs listed on this page or require assistance with the development of any form of reliable / secure / safe embedded system, then please do not hesitate to contact us.

In some cases, our customers use ReliabiliTTy technology to build a ‘TT Wrapper’: this is a monitoring unit that is used to improve confidence in the safe operation of a (pre-existing) complex component or system.
Here are some examples of TT Wrappers:
- A controller for an autonomous road vehicle (ISO 26262, ‘ASIL D’)
- A controller for a medical infusion pump that contains ‘SOUP’ (IEC 62304, ‘Class C’)
- A unit for confirming that a machinery-operator is ‘in place’ (ISO 13849, ‘PL e’)
- A controller for a civilian aircraft system (DO-178C / DO-254)
‘TT Wrappers’ can provide an effective means of improving confidence in the safety of an existing design prototype (even where the prototype was not developed in full compliance with the relevant international safety standards). Used appropriately, a TT Wrapper can help organisations bring initial products to market quickly and safely, in a cost-effective manner.
In some cases, our customers apply ReliabiliTTy technology to build a complete ‘TT System’.
Here are some examples of such systems:
- An automotive ECU designed using ‘ASIL decomposition’ (ISO 26262, ‘ASIL B’)
- A ‘Steering-Column Lock Controller’ for a high-volume passenger car (ISO 26262, ‘ASIL D’)
- An industrial monitoring system (IEC 61508, ‘SIL 2’)
- A controller for an industrial robot (IEC 61508, ‘SIL 3’)
- A controller for a domestic washing machine (IEC 60730 / IEC 60335, ‘Class B’)
- A space-based control system (ECSS-E-ST-40C, ECSS-Q-ST-80C)
Where practical, we recommend use of a fully-TT design (rather than a TT Wrapper) in situations where the organisation needs to improve confidence in the system reliability and robustness. In some cases, we find that our customers are exploring a TT Wrapper as a first design option, to be followed by a fully-TT system for the second-generation product release. Where required, we can assist with such a ‘Wrapper first’ development process.
Do you need to create an embedded system that is reliable / secure / safe?
This page provides a list of examples of the type of project that we can support.
These are simply examples: if your organisation needs to create reliable / secure / safe embedded systems – in any sector – then we may be able to help.
Our ReliabiliTTy Technology Evaluation Licence (RTEL) packages provide a cost-effective and time-efficient way of exploring the benefits that our state-of-the-art TT technology can provide for your business.
- include 2 days of one-to-one design support, helping to ensure that your team can prototype their first TT product successfully, at minimal cost;
- may also include our popular TTb Training Course (delivered on your company site).
