Temporal Logic and Model Checking
No. of lectures: 8
Suggested hours of supervisions: 2
Prerequisite course: Logic and Proof
The aim of the course is to introduce the use of temporal logic for specifying properties of hardware and software and model checking as a method for checking that properties hold or finding counter-examples.
- State transition systems. Representation of state spaces. Reachable states.
- Checking reachability properties. Fixed-point calculations. Symbolic methods using binary decision diagrams. Finding counter-examples.
- Examples. Various uses of reachability calculations.
- Temporal properties. Linear and branching time. Intervals. Path quantifiers.
- Temporal logic. Brief history (Prior to Pnueli). CTL and LTL. Standarised logics: PSL.
- Model checking. Simple algorithms for verifying that temporal properties hold. Reachability analysis as a special case.
- Applications. Simple software and hardware examples.
- Advanced methods. Very brief introduction to recent development, e.g. Counter-example guided abstraction refinement (CEGAR).
At the end of the course students should
- be able to write properties in a variety of temporal logic;
- be familiar with the core ideas of model checking;
- understand what commercial model checking tools can be used for.
