AM2631-Q1: Can the AM2631 support ASIL-B

Hi BU,

Could you help evaluate if the AM2631 can support ASIL-B or not? Since the AM2631 only has one core, and can not implement lock-step, I think it will be hard to achieve the hardware DC for ASIL-B target then. So I want to get your confirmation.

Regards,

Will

Hi WiIl,

Yes, the AM2631 is developed to be ISO 26262 compliant for ASIL-B compliance.

To meet the >99% single point fault metric for ASIl-D, the lockstep core is critical to provide redundancy. For ASIL-B, it is not necessary because the requirement is a little less stringent at 90%.

Hi QJ,

Thanks for your inputs. A further question is that do we have plan to get the ASIL-B certificate for AM2631?
