Winter Term 2016/17

On this page you find all the courses offered by the chair of Software Engineering in the winter term 2016/2017 as well as respective slides and accompanying exercises.

Cyber-Physical Systems I - Discrete Models (Lecture)

Model checking is a technique for the automatic verification of hardware or software systems. Given such a system and a specification of its intended behaviour, a model checker finds out whether the system satisfies the specification. Model checking has made enormous progress since its invention in the 1980s; today it is possible to verify entire CPU designs, and so all major microprocessor companies use and develop tools for this purpose. Software verification is more challenging than hardware verification and an active research topic (pursued at the chair for Software Engineering, for instance!). Recent years have seen interesting progress in this area as well. The industry has already started using these techniques to check, e.g., safety-critical embedded systems, and software libraries; yet, many research challenges, both theoretical and practical, lie ahead of us.

Decision Procedures (Lecture)

Decision Procedures are the basis for program verification: The task of program verification is to give a formal proof that a program meets its specification. This amounts to determining the truth value of a logical formula. A decision procedure is an algorithm that can for a certain type of formulas decide whether the formula is true or false. We will investigate decision procedures for different logics. Starting with propositional logic we will investigate decision procedures for logics with integers, reals, recursive structures (lists and trees), arrays, etc.

Software Design, Modelling, and Analysis in UML (Lecture)

The model-driven approach to software and systems development proposes to address quality and complexity issues in the development process. The usage of modelling languages not only for documentation, but, e.g., for automated analysis, test generation, and code generation is gaining momentum in particular in the context of (safety) critical software development. The necessary pre-requisites are a semantically founded modelling language and methods and tools for analysis. We will take the Unified Modelling Language (UML) as an example and demonstrate how to equip a relevant sublanguage (sometimes referred to as executable core) with a precise meaning in line with the official standard documents. To complement these discussions, we provide access to a contemporary UML modelling tool and use it for some of the exercises.

Softwarepraktikum (Nicht für B.Sc. Informatik und B. Sc. ESE)

In diesem Praktikum soll ein Softwareentwicklungsprozess, beginnend bei Anforderungserhebung über Entwurfsphase bis hin zur Implementierung, die Organisation der Arbeit innerhalb einer Gruppe und der Umgang mit komplexen Systemen erlernt werden. Die Teilnehmer werden von den Betreuern in Gruppen eingeteilt und müssen eine bestimmte Aufgabenstellung realisieren. Hierzu müssen sie sich selbst organisieren, die Anforderungen definieren, Arbeit geschickt auf Gruppenmitglieder verteilen und neue Technologien selbstständig erlernen.

Automata Theory (Seminar, Proseminar)

In the lecture about theoretical computer science you have seen finite automata, pushdown automata and Turing machines. All three of them operate on finite words. However there are other automata models and automata that do not operate on finite words, but e.g. on infinite words, on nested words, on trees, etc. In this seminar we will have a look at automata models that you have not seen in the lecture on theoretical computer science.

Program Analysis & Software Testing (Seminar)

Program analysis is the research area that studies the automatic analysis of computer programs. The methods that are developed in this research area e.g., help programmers to understand complex programs, allow compilers to optimize their code, and enable computers to check the correctness of programs. In this seminar each student will study a research paper and give a talk in which he/she presents a summary of the paper.

Advanced Topics in Requirements Engineering (Seminar)

Requirements engineering is an integral part of every (software) development process. The specification gained during requirements engineering defines the baseline for the product and acts as a starting point for (formal) verification and testing. The process of obtaining requirements themselves, ensuring that a requirements fulfill certain properties (e.g. having no inconsistencies or errors) and using requirements in formal verification and testing is an active research topic. In this seminar we will take a look at interesting research in the field of requirements engineering.
