Model Checking (SS 2022)
Table of Content
Model checking is a widely used technique for automatic verification and debugging of both software and hardware, with the power to reveal subtle errors that remain undiscovered using testing.
Therefore, model checking is an effective technique to expose potential design errors and improve software and hardware reliability, and it is gaining wide industrial acceptance.
Its inventors Edmund M. Clarke, E. Allen Emerson, and Joseph Sifakis have been awarded the significant Turing award in 2007.
How does model checking work? What are its underlying principles?
This is the focus of this course! Model checking is based on well-known paradigms from automata theory, graph algorithms, logic, and data structures. In the course, we first explain what these models actually are. We introduce temporal logics (e.g., LTL and CTL) to formalize various classes of system properties such as safety, liveness and fairness, and discuss in detail model checking algorithms for these logics.
As part of the practicals accompanying the lecture, you will build your own simple model checker that supports two popular algorithms. Here, we first introduce you to the basics of hardware implementations, safety and liveness, as well as symbolic representation and SMT solvers. Afterward, we use these building blocks to implement the bounded model checking algorithm you will learn in the lecture. Finally, we extend the BMC implementation so it can make unbounded proofs using K-Induction.

There are two ways to get a grade for the lecture: you do the homework or you take an exam.
If you do the homework, you will get a grade for the course. To get a passing grade, you can skip at most two homework exercises. Otherwise, there are 10 points per homework, 50% is a passing grade and the grades above that are divided evenly.
Homework is done in groups of one or two persons. When you submit your homework (per email), be sure to include the names and immatriculation numbers of all group members.
If you don’t want to do the homework or you get a failing grade for the homework, you can do a regular exam. Please let us know when you want the exam!
The practicals are done individually and consist of three assignments with point distribution 30/40/30. We follow the standard grading scheme, where you need more than 50% of the points for passing, and all other grades are distributed evenly in 12.5% increments. In addition to automated tests, we also rely on manual inspection of your submissions. The assignments will usually be presented after the lecture. The practicals time slots will be used for assignment presentations and tutorials.
Question hours regarding the assignments will be held virtually on our Discord channel on Wednesdays at 10:00.
Communication and Venue
Lecture and practicals are both on campus. However, we also encourage students to join the #MC channel on the official IAIK discord server, where you can talk with other students, ask us questions about the courses and get updates.
