Hello

As safety manual say there is a core test lib to ensure the functional safety of CPU core.

Can it cover FPU?  if not, is FPU considered non safety-related? that means can not be used as safety related arithmetic.

Thanks

We didn't consider FPU for safety application. Core test library doesn't cover FPU. 

Can you elaborate over FPU safety application? maybe we can discuss over other measures if applicable.
