or at least principles behind it when one is doing this reasoning in a style of separation.

In the first part of the course, we will engage in the formal verification of reactive systems. Students learn the syntax and semantics of the temporal logics LTL, CTL, and CTL* and their application in the specification of e.g. safety and liveness properties of systems. Simple models of systems are designed and verified using model checkers and dedicated frameworks for asynchronous and synchronous reactive systems, and the algorithms working in the background are explained.
The second part of the course focuses on functional correctness of programs; more precisely, we discuss the theory of pre- and postconditions, Hoare triples, loop invariants, and weakest (liberal) preconditions, in order to introduce automatised correctness proofs using the Hoare calculus.
Students are going to acquire the following competences:
Wissen- Reproduce the definition of syntax and semantics of temporal logics LTL, CTL, and CTL*.
-
Reproduce the definition of semantics of a simple programming languages like IMP, with special focus on axiomatic semantics (Hoare rules).
-
Explain how CTL can be characterised in terms of fixpoints.
-
model checking
-
specification and verification of reactive systems,
-
verification of functional correctness or memory safety of simple programs.
- Choose the optimal tool for a given verification or specification problem.
-
Differentiate between safety and liveness properties.
