is a functional safety, pre-certified, Real Time Operating System
(RTOS) for embedded processors. It delivers top performance and pre-certified
dependability, whilst utilising minimal resources.
Developed by WITTENSTEIN high integrity systems (WHIS), a FreeRTOS partner that specialises in safety
Available pre-certified to IEC 61508 SIL 3 and ISO 26262 ASILD by TÜV SÜD
Supports a wide range of international development standards
Based on the FreeRTOS functional model and therefore easy to migrate to
SAFERTOS is delivered with a Design Assurance Pack (DAP) which contains
every design artefact produced during the full development life cycle.
The DAP ensures an easy route to achieving certification of SAFERTOS
once integrated into a Safety Critical device.
SAFERTOS is based on the functional model of the FreeRTOS kernel,
however, it is not the FreeRTOS kernel. It has been completely
re-designed by a team of functional safety experts at WHIS. Their
engineers took the FreeRTOS kernel functional model, subjected it to a
full HAZOP, and generated a set of safety requirements. The resulting
functional and safety requirements sets were put through an IEC 61508-3
SIL 3 development life cycle, creating the SAFERTOS code base and DAP.
Certifying SAFERTOS integrated within a product is a simple and hassle-free process.
Contained within the Design Assurance Pack, or DAP, (which is included
with SAFERTOS purchases) is the all-important Safety Manual. The Safety
Manual explains exactly how to install and integrate SAFERTOS into your
development environment. Following the concise instructions will also
generate the evidence required by your auditors to confirm the process
has been followed correctly. This removes the need for re-testing on
your target hardware, and provides a solid dependable platform for your
development. The DAP contains all the Planning, Design and Verification
artefacts, and is specific to the selected Processor/Compiler combination.
For every RTOS purchased, WHIS supplies 12 months free Support and
Maintenance. For any question you want answered, any support or guidance
that you need during design decisions, they are right there ready to
help you. WHIS engineers enjoy sharing their engineering experiences,
and take great pride in providing a responsive, friendly and helpful
service. To see more about the support offered, including technical
help and updates,
view the WHIS support page.
One of the advantages of a Support and Maintenance contract is the
re-validation of SAFERTOS. Once per year, on request, WHIS will
re-validate SAFERTOS for a newer version of the compiler, meaning you
always have access to the latest tools.
