The ASIL D certification allows OLEA-based solutions to be used for the highest level of safety-critical designs in automotive applications. The certification was granted after SGS-TÜV Saar performed an in-depth audit to assess the quality, rigorousness and completion of Silicon Mobility’s analyses while designing, describing and completing the defined safety goals. The FPCU device is a Safety Element out of the Context (SEooC) for defined powertrain applications.
Silicon Mobility’s OLEA T222 FPCU (Field Programmable Control Unit) features an architecture that combines the hardware flexibility of the AMEC real-time control unit with the software flexibility of a standard processor in a single chip. AMEC provides parallel data paths between acquisition and actuation peripherals and the Flexible Logic Unit (FLU). The FLU is automotive specific, robust embedded programmable logic that has multiple DSP resources. OLEA T222 FPCU also features SILant, an ASIL-D functional safety integrated architecture that has been designed to offer reliable countermeasures against various faults and can increase fault coverage up to the application level.
The OLEA T222 FPCU comes with ISO 26262 work products including a safety manual and FMEDA tooling calculating the safety metrics in accordance to customer system specifications.
