Static Analysis and Verification

FIT-SAVAcad. year: 2024/2025

Introduction of basic terms, such as analysis and verification, formal analysis and verification, soundness and completeness, logical and physical time, safety and liveness, etc. Overview of various approaches to static analysis and verification and other alternative verification approaches. Introduction to temporal logics as one of the classical means of specification of desired system properties. Model checking for the LTL logic using Büchi automata. Use of automatically refined predicate abstraction as one of the most successful approaches towards model checking of software. Abstract interpretation as one of the most successful methods of static analysis: principles, algorithms, and an overview of the most prominent abstract domains. Data flow analysis: basic terms and principles, classical analyses used in optimizing compilers, design of new analyses, pointer analyses. Solving of the SAT and SMT problems, which are used (not only) within a lot of verification approaches. Verification based on symbolic execution, bounded model checking, and k-induction. Deductive verification of annotated programs (functions' pre- and postconditions, loop invariants). Binary decision diagrams as a means of efficient storage of (not only) state spaces. Introduction to automatic verification of termination of program runs (absence of looping) and automatic analysis of complexity.

Rules for evaluation and completion of the course

  • An evaluated project for 30 points. 
  • A final examination for 70 points. 
  • To be allowed to sit for the written examination, a student is to earn at least 15 points during the semester.

    • A project focused at obtaining first-hand practical experience with a selected tool for static analysis or verification and the principles it is based on, reproduction of case studies available for the tool, student's own experiments with the tool, and composition of a report about the tool and the performed experiments.

    Aims

    The goal of the course is to get students acquainted with various methods of static analysis and verification that are commonly used in practice for finding bugs or proving correctness of systems. Students will be introduced to a variety of methods of static analysis and verification with their advantages and disadvantages. Moreover, the course will also present an overview of current tools that implement the discussed techniques and students will, through a project, obtain a first-hand practical experience with a chosen tool.

    Students are acquainted with principles and methods of static analysis and verification and with their application within the process of designing computer systems. Students know capabilities and the basic ways of using computer-aided tools for static analysis and verification. Acquired knowledge about the significance and possibilities of using methods and tools of static analysis and verification within the development of various kinds of systems and about their growing use in practice.
