Robo VV process starts with logical system description and set of requirements. In case of the transmission line reliability this might consist of the communication protocols and error handling procedures. System requirements describe constrains that needs to be validated, eg. state of the system after connection timeout.

In the first phase of an VV process, simulation of the system is performed and potential critical faults are identified with methods from our partners (Sim-based FAISL and Assessment of Cybersecurity-informed safety). If simulation results pass all requirements then changes of the system are implemented and validated in the daily reggression tests.

After passing reggression tests, the system is tested with model based methods from our partners (Software implemented fault injection and penetration tests). For these methods exists testing setup of a whole system. Results of all the metods are passed as output of the VV process and used to alter system description.
