UN-FIT is a fault injection tool for microprocessors, developed at the Universidad Nacional de Colombia, adaptable to different architectures. The current version of UN-FIT is based on QEMU and allows injection campaigns on ARM and RISC-V ISA based-processors.

The arguments to run UNFIT are:

• File name

• Qemu machine

• Qemu memory

• Number of injections

• Register with the result (or direction address)

• Result size in bytes (0 to result in the register)

• Injection mode

• Number of processes

  UNFIT requires a program execution trace file. A script is supplied to get the trace file.

In the example_ARM directory there are the necessary files and instructions for using the tool with an example program on ARM architecture.
