Hi Is it necessary to test all GPIO(output ports)(STM32G070KB)for class B compliance? writing data to outputs ports make problem in my product.

In the ST STL library (en.x-cube-classb-v2-3-0) they have used both watchdog timers. Is it necessary to use both watchdog timers(IWDG and WWDG) for class B compliance?

The ST self-test library(en.x-cube-classb-v2-3-0) tested both watchdogs( IWDG and WWDG). Is it necessary to test both IWDG and WWDG for class B compliance? In the self-test library, they used both watchdogs. If I use one watchdog timer let's say WWDG...

Hi,Can somebody help me to understand the below thing?How to detect CPU registers stuck at faults? If CPU registers are stuck at fault, How can instruction send/stored in that register will be the actual one? I mean to test CPU register stuck at faul...

For IEC60335-1 class B compliance, CPU registers should function well(Should not be stuck at faults). To test those faults we need to send/store some instructions to those registers. What if those registers are stuck at fault? I mean If it is stuck a...
