FAQ
What is voltage glitching?
Voltage glitching is a fault injection technique that momentarily drops or spikes the power supply voltage to induce errors in a chip's operation, often used to bypass security checks.
How accurate are the estimates?
The calculator provides theoretical estimates based on your inputs. Actual results may vary due to hardware specifics and environmental factors. Use these as starting points for experimentation.
What glitch types are supported?
The tool supports VCC (power supply), clock, and reset glitching types, covering common fault injection methods.
Can I use this for any microcontroller?
Yes, the calculator is generic and works with any target voltage and clock frequency. However, always verify with your specific hardware.
