120 credits including Program design, Algebra, Logic and Proof Techniques, Algorithms and Data Structures, Programming Theory (or equivalent courses).

Learning outcomes

In order to pass, the student must be able to

  • understand how formal methods fit into the software development process,
  • explain the principles of model-based specification and refinement-based program development,
  • explain the B-method or other used method,
  • understand and independently write model-based formal specifications,
  • independently carry out formal development of programs with tool support.

Content

Overview of specification techniques. Model-based specification. The B specification notation or similar notation. The program development process. Verification and validation. Simulation and other methods to validate specifications. Implementation models. Overview of axiomatic semantics. Invariants. Weakest preconditions. Verification by refinement. The B-method or similar method. Proof obligations. Proof techniques. Tools for formal software development.

Instruction

Lectures and seminars. During the course, students will carry out a program development project including writing a formal specification and developing provably correct program code.

Assessment

Seminars (3 ECTS credits) and the project (7 ECTS credits).
