Examples of TT Wrappers

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) code frameworks that incorporate patented run-time monitoring techniques.empty_space

In some cases, customers use our code frameworks 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 that are implemented using our code frameworks:


We always recommend use of a TT System when this is possiblepossible, because use of a System can provide higher levels of diagnostic coverage than a Wrapper, as well as increased confidence in system reliability.  However, where (for example) designs need to employ a general-purpose operating system; or other ‘Software Of Unknown Provenance’ – SOUP; or ‘unqualified’ hardware components, use of a TT Wrapper may provide the basis for a practical and effective design solution.  In addition, use of a Wrapper can provide an effective means of prototyping a safety-related system.
