News
24.11.2015 — Schedule update! There will no longer be a formal exercise class on 25.11. The assistant, however, will be available for questions immediately after the guest lecture. The exercises on testing will be covered during the first half of the class on 2.12; the second half will cover general exam preparation and any further questions you might have.
27.10.2015 — Video lectures from the recent ETH Workshop on Software Correctness and Reliability are now available online. If you're interested in what's going on at the cutting edge of program verification research, they will certainly be worth a look.
07.10.2015 — The project description is now online. Please remember to register your teams before 14th October!
20.07.2015 — A tentative version of the course schedule is now online.
Course objectives
252-0239-00L Software Verification
After successfully taking this course, students will have a theoretical and practical understanding of:
- The principles behind fundamental software verification techniques, including Hoare-style axiomatic semantics, abstract interpretation, model checking, and testing.
- Application of the principles to the construction of verification tools, in particular program provers.
- Research challenges in these areas.
Course description
The idea of software verification has been around for decades, but only recently have the techniques become mature enough to be implemented and be applicable in practice. Progress has been made possible by the convergence of different techniques, originally developed in isolation.
This course embraces this diversity of approaches, by surveying some of the main ideas, techniques, and results in software verification. These include in particular:
- Axiomatic semantics, which provides a foundation of program correctness proofs by supplying a rigorous semantics of programs.
- Abstract interpretation, which provides a general framework to express and design static techniques for program analysis.
- Model checking, which provides efficient techniques for the exhaustive exploration of state-based models of programs and reactive systems.
- Testing, which provides the counterpart to exhaustive techniques by defining dynamic analyses to detect programming mistakes and correct them.
To demonstrate some of the techniques in practice, the course will offer a practical project requiring the application of verification tools to illustrative examples.
