Reliability Analysis in Embedded Systems


2 SWS (5 ECTS)

Fields of study:

Informatik, CE und I&K

Registration via Studon


Ever shrinking technologies has increased the chance of failure in electronic systems (e.g., a bit flip in a memory cell, a break-down in a transistor, an open/short circuit) which may threat the functionality of the system, for example, by corrupting the outputs.

These malfunctions rise the following questions:

  • What are the consequences of unexpected failures in a system? May your laptop lock for a while or may an airplane crash?
  • Do you rely on a system in the presence of these failures? Do you rely on your bank when there is a chance of an unexpected change in your account’s balance?
  • Which systems are more prone and critical to failures? What would happen if brakes in cars fail as often as dropouts in audio players?
  • How can prediction and prevention, or detection and recovery from failures be employed in a system to ensure correct output? How much the data measured by medical devices are trustworthy?

The purpose of this seminar is to answer these questions following the study of reliability as a measure to analyze the effects of various failures in electronic systems at different levels of abstraction, e. g., VLSI-, transistor-, gate- and system-level.

Reliability is defined as the probability that a system works properly for a specific period of time in the existence of probable failures. Different reliability analysis and improving techniques have been proposed in the literature. In this seminar, each student will be provided by some scientific publications which should be compared with respect to their challenges and proposed solutions. Then, a talk is given by each student in which she/he should conclude her/his studies, and a discussion about the topic is hold by all participants. Moreover, you shall prepare a short report on your subject in the range of 6 to 8 pages.
