Usually a leaking code runs challenges, one challenge giving a power trace. A challenge is the execution of a code with a specific set of data. This set of data is given in the input of the leakage simulation. For example, one can imagine that the leaking code is a symmetric encryption and one wants to study its power leakage according to the message and the secret key. Then, a challenge is the simulation of the leakage for a specific message and for a specific secret key.
So, the classical form of ```project.c``` is the following one:

- Stop the record of the power leakage (end a power trace) with ```endtrigger```.
- Eventually output some data with ```printbyte```.
- Indicate to ELMO tool that the simulation is finished with ```endprogram```.
The file ```projectclass.py``` contains a subclass of ```SimulationProject```. It is the description of the ```project.c``` file for the ELMO tool, in order to correctly realise the simulation. It also provides methods to manage the simulation (see following sections).
- The classmethod ```get_binary_path(cl)``` must return the relative path of the leakage binary (```project.c``` correctly compiled).
- The method ```set_input_for_each_challenge(self, input, challenge)``` must write a ```challenge``` in ```input``` using the function ```write```.
