Functional Safety

More and more industries are now adopting Functional Safety standards, such as IEC 61508, either for legislative or due-diligence reasons. As recognition widens, there is a growing demand for electronic products (“elements”) which are certified for use in 61508 systems.

FS experts.

As equipment designers, Mutech designs “elements” or modular “subsystems” that form part of a safety instrumented system.

Mutech has, over the years, produced a process and set of tools to make functional safety development as efficient as possible. The approach is highly test driven, with all tests (both hardware and software) easily repeated at the press of a button, hence, if a small change is made in the software or hardware then every test can be re-run within a couple of minutes.

Software development for functional safety is, at first glance, highly documentation and verification heavy compared to most other software development. It is true that there is a considerable amount of up-front work required before the first line of code is written, but the detailed process produces highly reliable software first time, thus minimising the back end process of fixing software bugs.

Mutech are used to their designs being third party assessed, and hence have documentation templates designed for assessment by the most rigorous of assessors. Mutech can provide liaison with assessors to make the process as efficient as possible.
