Notes for users

• Registers number must be filled manually default 256. It can be found in Profiler.py as active_registers
• Execution must give output result as a text file and it must be specified in config.py.

To do list

• SDC check script
• Add kill script in Hang Condition
• Find Maximum register number
• Try with different examples
• Make optimizations
• Convert program into 3-step Injector
• Add conditional Breakpoints
• Prepare Config File
