CS-550 / 6 crédits

Enseignant: Kuncak Viktor

Langue: Anglais


Summary

We introduce formal verification as an approach for developing highly reliable systems. Formal verification finds proofs that computer systems work under all relevant scenarios. We will learn how to use formal verification tools and explain the theory and the practice behind them.

Content

Topics may include (among others) some of the following:

  • Importance of Reliable Systems. Methodology of Formal Verification. Soundness and Completeness in Modeling and Tools. Successful Tools and Flagship Case Studies
  • Review of Sets, Relations, Computability, Propositional and First-Order Logic Syntax, Semantics, Sequent Calculus.
  • Completeness and Semi-Decidability for First-Order Logic. Inductive Definitions and Proof Trees. Higher-Order Logic and LCF Approach.
  • State Machines. Transition Formulas. Traces. Strongest Postconditions and Weakest Preconditions.
  • Hoare Logic. Inductive Invariants. Well-Founded Relations and Termination Measures
  • Linear Temporal Logic. System Verilog Assertions. Monitors
  • SAT Solvers and Bounded Model Checking
  • Model Checking using Binary Decision Diagrams
  • Loop Invariants. Hoare Logic. Statically Checked Function Contracts. Relational Semantics and Fixed-Point Semantics
  • Symbolic Execution. Satisfiability Modulo Theories
  • Abstract Interpretation
  • Set theory for verification

Learning Prerequisites

Recommended courses

CS-320 Computer language processing

Important concepts to start the course

Discrete Mathematics (e.g. Kenneth Rosen: Discrete Mathematics and Its Applications)

Learning Outcomes

By the end of the course, the student must be able to:

  • Formalize specifications
  • Synthesize loop invariants
  • Specify software functionality
  • Generalize inductive hypothesis
  • Critique current software development practices

Teaching methods

Instructors will present lectures and exercises and supervise labs on student laptops.

Expected student activities

Follow the course materials, take mid-term, and complete and explain projects during the semester.

Assessment methods

The grade is based on the written mid-term, as well as code, documentation, and explanation of projects during the semester. Specific percentages will be communicated in the first class.
