A Novel approach to implement FuSA Feature in Complex Automotive SoCs Using USF
DescriptionOne of the critical requirements for any embedded application is FuSA (Functional Safety) because it is essential that all the embedded devices function correctly and safely under any faulty or failure scenarios. When it comes to automotives, as per ISO 26262 standard, any failure, be it systematic or random, needs to be addressed during the development itself.
This paper focuses on two safety strategies being widely used in automotives (TMR : Triple Module Redundancy & DCLS : Dual Core Lock Step) and how by using the new USF (Unified Safety Format), these safety mechanisms can be implemented in automotive designs with minimal user effort & reduced run time.
Earlier both the strategies were achieved using custom coded scripts and user was required to manually create bounds for the Safety Main and Shadow modules. Also, the TMR solution with a single voter cell was not supported.
With USF format support, the TMR conversion can be achieved using a single voter cell and an effective physical separation can be achieved for the Main and Shadow modules.
This paper will also highlight the run-time gain with the new USF based approach
