The OLEA® APP INVERTER software application for electric vehicle traction chain control is now ISO 26262 certified.



Today, Silicon mobility announced that OLEA® APP – INVERTER T222, a traction inverter motor control application, is now certified to ISO 26262 ASIL-C by SGS-TÜV Saar. This achievement makes Silicon Mobility the first company to offer a complete ISO 26262-certified automotive solution that includes ASIL-D certification. OLEA®FPCU T222 chip, OLEA® COMPOSER development framework and OLEA®LIB Libraries (until ASIL-D certified) and now the OLEA® APP – T222 INVERTER application (ASIL-C certified). Comprehensive safety work products are available for designers and functional safety managers, along with the certification report. Today, OLEA® technology is the leader in enabling efficient control of the most critical applications such as inverter and electric motor, DC-DC and OBC.

OLEA® APP – T222 INVERTER – next technology control for electrified powertrains

OLEA® APP – T222 INVERTER is a motor control application software for OLEA® T222 FPCU, enabling optimal control of electrified powertrains. Built as a software platform to control a wide variety of technologies and topologies, OLEA® APP – T222 INVERTER enables high performance, real-time and safe control of advanced power electronics and electric motors. Today it is certified according to ISO 26262 ASIL-C from SGS-TÜV Saar and provides support for ASIL-D certification for transmission system integration.

OLEA® APP – T222 INVERTER functional safety is based on three key elements:

the on-board safety hardware resources with SILant® technology dedicated to the functional safety mechanisms of the OLEA® T222 FPCU

the application level software security mechanisms implemented in OLEA® APP – INVERTER T222

the software architecture built with Freedom From Interference between functional safety and the functional partition

Safety work products include certification reports, safety manuals, and FMEDA (Failure Modes, Effects, and Diagnostic Analysis) tools.

OLEA® – A complete full-stack automotive solution

OLEA® APP – T222 INVERTER is the latest product in the OLEA® portfolio to be ISO 26262 certified after Silicon Mobility’s OLEA® T222 FPCU semiconductor in March 2020 and OLEA® COMPOSER, a software independent design workflow powered by OLEA® LIB, a control software component library, in March 2022.

OLEA® T222 FPCU, a flexible, real-time and safe automotive semiconductor, is ISO 26262 ASIL-D ready certified by SGS-TÜV Saar. A solution designed to process critical information faster with 100% predictability and accuracy. The functional safety of the OLEA® T222 FPCU includes SILant®, a patented hardware technology integrated into the chip. SILant® incorporates a security architecture that goes beyond ASIL-D SEooC (Safety Element out of Context) objectives. Most importantly, the OLEA® T222 FPCU enables application-level fault coverage with flexible and secure hardware. In addition, the FPCU not only enables ASIL-D design, saves CPU processing power, enables software code simplification, shortens fault reaction processing time interval, etc. The OLEA® T222 FPCU is AECQ-100 Grade 1 qualified.

OLEA® COMPOSER and OLEA® LIB are ISO 26262 certified by SGS-TÜV Saar, for the development of security-related software applications – using OLEA® T222 FPCU – up to ASIL-D. OLEA® COMPOSER and OLEA® LIB safety work products come with certification reports, safety manuals, tool criteria evaluation reports, tool qualification plans, abnormal conditions and fault reports.

Safety Work Product Records

Starting in 2022, Silicon Mobility offers a complete ISO 26262-certified off-the-shelf solution that customers can design. As part of its safety work, the company maintains a comprehensive set of functional safety documentation available to designers and safety managers. These deliverables include, but are not limited to, development process design rules, specifications, verification reports, functional requirements, security requirements, and dependent failure analysis (DFAR) reports.

According to ISO 26262, this unique set of certifications confirms that the OLEA® solution is suitable for vehicle manufacturers and automotive third parties to design safety-related automotive applications such as electrified powertrain control.
