ChipSHOUTER Users Manual
: Simple EMFI Target (CW322)
32
The STATUS, FAULT, and OPEN LEDs on the ChipSHOUTER
should light up.
3.
Screw one of the 4mm injection tips onto the High
voltage output connector of the ChipSHOUTER, this
should cause the FAULT and OPEN lights to go off.
4.
Hold the ARM button until the arming chime sounds and
release the button. The system is now armed and ready
on inject a glitch.
5.
Hold the probe very close to the chip on the Simple
Target and press the PULSE button on the ChipSHOUTER
to inject a field pulse.
6.
Move the probe across the chip while holding the
PULSE button and observe the effect on the LEDs.
In some locations the chip will reset or stop working. In
others the chip will blink the fault LED, indicating that
the multiplication operation has been corrupted. This shows
a successful fault injection where the intended output of
the device has been changed without directly interfacing
with the device in any way. This is the heart of EMFI.
CAUTION: Observe proper ESD handling require-
ments with the board.
CAUTION: Fault injection can permanently de-
stroy the injection target. Always start at a
further distance and move towards the target until
you see fault interactions.
