系統(tǒng)驗證：自動機和行為等效培訓(xùn)

Behavioural modelling

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 systems does exactly what it is supposed to do. The techniques put forward

in system validaton allow to prove the absence of errors. It allows to design embedded system behaviour that

is structurally sound and as a side effect enforces 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.’Automata and behavioural equivalences' shows you how to look at system behaviour as state machines.

It discusses behavioural equivalences and illustrate these in a number of examples and quizzes.

This module introduces automata or labelled transition systems as the basic way to model the behaviour

of software controlled systems. It subsequently addresses the question

when such behaviours are equivalent.Reading material. J.F. Groote and M.R. Mousavi.

Basic behavioural equivalences

This module shows the most important equivalences that express when

the behaviour of two automata can be considered to be equivalent.

It will become obvious that there are multiple of such notions, all fit for use under different circumstances.

Furthermore, the all-important notion of the internal or hidden action

is introduced with some associated behavioural equivalences.

More behavioural equivalences

This module elaborates on the equivalences provided earlier.

It is shown how it can be applied, especially to the alternating bit protocol.

Furthermore, a number of additional equivalences are introduced.
