Automotive ASIL readyMulti-Processor ArmCortex-M Subsystem

EnSilica’s Cortex-M processor subsystem enables fast custom IC development by allowing the customization of both processing performance and peripherals. The Cortex-M33 is ideal for medium workloads, and the subsystem leverages EnSilica’s reusable verification environment to accelerate time to market. For compliance with ISO 26262 and IEC 61508 standards, Arm provides a “safety package” for ASIL/SIL applications, which includes documentation on failure modes and safety mechanisms. EnSilica integrates this data through an FMEDA-based safety analysis process, achieving the required safety metrics at the SoC level while ensuring compliance and reliability in critical applications.

The EnSilica Cortex-M processor subsystem enables the development of custom IC’s with fast time to market. The processing performance of the subsystem can be tailored to customer requirements through the selection and customisation of the selected Cortex-M processor, the Cortex-M33 is seen as an ideal candidate for medium workload applications. The performance of the range of supported peripherals can also be tailored to customer requirements through the customisation of each peripheral. Fast time to market is supported by reuse of the EnSilica subsystem verification environment. Automotive or industrial safety standards require to perform a safety analysis against the prescribed safety requirements in order to introduce the necessary detection or prevention measures. For selected Cortex-M processors, Arm provide the so-called “safety package” for ASIL / SIL applications, containing a set of documentation necessary to ensure ISO 26262 / IEC 61508 compliance, like failure modes description and safety mechanisms. EnSilica integrates this information through an FMEDA-based safety analysis process to obtain the necessary safety metrics at SoC level, requested by the mentioned standards
