Express Logic’s FileX® File Management System Certified For Use in Safety-Critical Embedded Systems and IoT Devices



Certification makes FileX the ideal choice for applications that must meet IEC
61508, IEC 62304, ISO 26262, and EN 50128 safety standards

San Diego, CA — June 26, 2016 — Express Logic, Inc., the worldwide leader in
royalty-free real-time operating systems (RTOS), today announced that its
industry-leading FileX® FAT/exFAT file management system stack is the first
Industrial Grade commercial file management system to be certified by SGS-TÜV Saar
for embedded development in safety-critical systems. FileX joins Express Logic’s
popular ThreadX® RTOS and high-performance NetX Duo™ TCP/IP stack to form one of the
industry’s most comprehensive suites of products for embedded applications and IoT
devices. FileX has achieved the highest level of certification for the rigorous
International Electrotechnical Commission (IEC) 61508 SIL 4, IEC 62304 Class C, ISO
26262 ASIL D, and EN 50128 SW-SIL 4 safety standards.
SGS-TÜV Saar, formed through a joint venture of Germany’s SGS-Group and TÜV
Saarland, is the leading accredited, independent company for testing, auditing,
verifying, and certifying embedded software for safety-related systems worldwide.
The industrial safety standard IEC 61508 and all standards that are derived from it,
including IEC 62304, ISO 26262, and EN 50128, are used to ensure the functional
safety of electrical, electronic, and programmable electronic safety-related medical
devices, process control systems, industrial machinery, and railway control systems.

SGS-TÜV Saar has evaluated the relevant parts of Express Logic’s modified waterfall
development process for FileX, with phase overlap and phase blending, to ensure that
best development practices have been followed at these phases:

Requirements management
Design
Implementation
Verification
Maintenance

Using an extensive test suite, SGS-TÜV Saar rigorously reviewed all testing and
features of FileX. The FileX test suite, composed of a large number of application
simulations, effectively performs functional “black box” testing over the entire
FileX TCP/IP stack. The testing exercises 100 percent of the generic FileX C code —
including 100 percent branch coverage. Express Logic’s FileX Safety Manual documents
these quality-assurance measures, which enable developers to use FileX in
safety-critical software development for even the most rigorous Safety Integrity
Level (SIL 4) and Automotive Safety Integrity Level (ASIL D) requirements, according
to IEC 61508, IEC 62304, ISO 26262, and EN 50128, without further qualification.

“The achievement of SGS-TÜV Saar certification for FileX will enable our customers
to simplify their certification process, thus saving project time and money and
reducing risk,” said William E. Lamie, CEO of Express Logic, Inc. “This
certification provides significant evidence of the exceptionally high quality of
our FileX product.”
