System Validation 3: Requirements by Modal Formulas

System Validation is the field that studies the fundamentals of system communication and information processing. It allows automated analysis based on behavioural models of a system to see if a system works correctly. We want to guarantee that the system does exactly what it is supposed to do. The techniques put forward in system validation allow for proving the absence of errors. It allows you to design embedded system behaviour that is structurally sound and, as a side effect, forces you to make the behaviour simple and insightful. This means that the systems are not only behaving correctly, but are also much easier to maintain and adapt.
