I captured the glichted VCC and GLITCHOUT during voltage glitching attack.
- Chan 1: glitched VCC
- Chan 2: trigger
- Chan 3: clock
- Chan 4: GLITCHOUT
As you can see both the glitched VCC and GLITCHOUT don’t have straight edges and are bouncing a lot. VCC doens’t even drop to 0V, probably because the GLITCHOUT doesn’t have enough drive to pull the MOSFET.
To verify it, I disconnected the glitch signal between the two boards, and did a trace again:
The GLITCHOUT above is still having a bad shape. Is there anything I can do to improve it?
