One aspect of the invention relates to a method (100) for optimizing critical software, which consists in creating a variant of the critical software. This variant of the critical software is obtained by adding instructions to the set of instructions of each elementary interval of the critical software. These added instructions make it possible in particular to generate interference during the execution of the critical software. In addition, these added instructions also make it possible to measure the actual execution time of each elementary interval of the critical software to which the instructions have been added and to collect measurements relating to the demands placed on the hardware. The method according to the invention therefore makes it possible to evaluate critical software able to be used in the context of optimizing the critical software.
