Phaedrus Systems supports engineers at all stages of embedded safety-critical and high-integrity projects. Tools available include requirements capture for IEC 61508, EN 50128 , DO178 and nuclear applications, a SIL3 RTOS and compiler validation reports. Consultants have experience working on automotive, rail and aerospace applications, meeting standards such as IEC 61508 SIL4, and D0178B. Backing these is a wide range of other relevant embedded tools, including code checkers, USB and TCP/IP stacks, development kits, debuggers and ICEs.

Micrium uC/OS


RTOS Choice


Software engineers know that one size doesn’t fit all when choosing an RTOS.  That is why we have added to our existing RTOS portfolio Micrium’s µC/OS real-time kernel. This is really a family of modules, with versions certified for DO-178B, for FDA 510(k), for SIL3/SIL4 IEC for transportation and nuclear systems, and one 99% compliant with MISRA-C:1998. Additionally, Micrium has a range of communications stacks, including one for industrial control protocol, Modbus.  Read more at our Micrium pages.




Faulty Code


It seems as though the world is waking up to the fact that poorly developed software is dangerous.

The software problems for Toyota, Apple and SSL  could all have been improved radically by the use of controlled development processes, using tools such as Static Code Analysis, backed by formal code review.
