Will the AI model crash during radiated immunity (RS) testing of an industrial AI edge gateway?

The industrial AI edge gateway passed the IEC61000-4-3 10V/m radiated immunity test. The AI model ran continuously without crashing. Key design features include:

1. Enabling spread spectrum for the AI processor clock source and connecting it in series with a PBZ1608E600Z0T ferrite bead;

2. Adding termination resistors to the DDR address lines to reduce reflection sensitivity;

3. Adding a 0.1μF capacitor and ESD5V0D8B clamping to the reset circuit;

4. Applying conductive foam to the conductive gaps in the shielding housing.

Tested at 20V/m field strength, the AI inference ran for 200 hours without watchdog timer reset or crashing.
