Express Logic’s GUIX® Becomes the First Deeply Embedded GUI Solution Certified to SIL 4, ASIL D, and Medical Class C for Safety-Critical IoT Systems

Certification Makes GUIX® the Ideal Choice
for Products and Applications that Require Elegant Displays and Must
Meet Stringent Safety Standards

SAN DIEGO–(BUSINESS WIRE)–lt;a href=”https://twitter.com/hashtag/ARM?src=hash” target=”_blank”gt;#ARMlt;/agt;–Express Logic, provider of the comprehensive X-Ware IoT Platform®
powered by the popular ThreadX® real-time operating system
(RTOS), today announced that its deeply embedded GUIX®
graphical user interface run-time solution has achieved the highest
level of safety certification for the rigorous IEC 61508 SIL 4, IEC
62304 Class C, ISO 26262 ASIL D, and EN 50128 SW-SIL 4 safety standards.
This new certification performed by SGS-TÜV Saar is unique to the
embedded industry, making GUIX the only choice for safety-oriented
applications that have a user interface and require certification.

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 GUIX, with phase overlap and
phase blending, to ensure that best development practices have been
followed at these phases:

  • Requirements management
  • Design
  • Implementation
  • Verification
  • Maintenance

To make this assessment, SGS-TUV Saar based its evaluation on a rigorous
test suite for GUIX. The GUIX test suite is composed of a large number
of application simulations and effectively performs functional “black
box” testing over the entire GUIX software product. The testing
exercises 100 percent of the generic GUIX C code — including 100 percent
branch decision coverage. Express Logic’s GUIX Safety Manual documents
these quality assurance measures, which enable developers to use GUIX in
safety-critical software development that is required to meet even the
most exacting Safety Integrity Level (SIL 4) and Automotive Safety
Integrity Level (ASIL D), according to IEC 61508, IEC 62304, ISO 26262,
and EN 50128, without further qualification.

“We are fully committed to providing the best quality products – saving
our customers time and money and helping them reduce risk,” said William
E. Lamie, CEO of Express Logic. “The new certification of GUIX further
enables customers with user interface needs to leverage the benefit of
our safety- and security-certified best-of-class offerings.”
