Background Information
- Difficulties with voltage glitching
- FPGAs do everything at the same time - SRAM holds configuration
- Crowbar circuit
Setup
Hardware Setup
- SMA cable - Picture
Software Setup
- Script - Bitstream (same as Tutorial 1) - Glitch module setup
- Glitch only - HS-Glitch
- Same idea as Tutorial 3
Hints
- Might be easier on the edge of working conditions - Changing core voltage level - Changing clock speed
- CLKGEN output - CW305 PLL - Max speed depends on FPGA implementation
- Enable-only output
- Only use repeat and offset - EXTCLK for speed-up
