FIL3200 Design of Fault-Tolerant Systems 7.5 credits

Feltoleranta systemkonstruktioner

The aim of this course is to give students knowledge necessary to develop dependable systems. After completing the course, the students should be able to demonstrate the knowledge and skills required to implement and evaluate various fault-tolerant approaches. The course consists of 12 2-hour lectures and 6 1-hour exercises. The examination is based on 5 homework assignments, a midterm test, a final exam and a research project. The course will be given annually in the 4th period, jointly with the master-level course ID2218 Design of Fault-Tolerant Systems.

Intended learning outcomes *

The aim of this course is to give doctoral students knowledge necessary to develop dependable systems.  As our society becomes more and more reliant on computer, software and embedded systems, dependability of these systems becomes a critical issue. In airplanes, chemical plants or heart pace-makers a system's failure can cost people's lives or environmental disaster. After completing the course, the students should be able to demonstrate the knowledge and skills required to implement and evaluate various fault-tolerant approaches. More specifically, upon completion, students will be able to:

• Describe the state-of-the-art fault-tolerant design techniques. Justify their targeted applications and limitations. Describe how the dependability is assured in an exemplary application.

• Describe dependability means, attributes and impairments. Apply the knowledge to select a suitable set of attributes for a specific application scenario.

• Analyze and critically access the tradeoff among system dependability, performance, and cost. Exemplify some of the trade-offs that are available to designers of electronic and embedded systems.

• Explain the need for different redundancy techniques. Justify pros and contras of different redundancy techniques and select a suitable one for a specific application.

• Apply the knowledge to design a small electronic or embedded system with enhanced dependability. Explain how the dependability is assured in the system.

Examination *

  • EXA1 - Examination, 7.5 credits, Grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

In the examination part, the following is included:

- five homework assignments (20%, grade pass/fail)

- a midterm exam (20%, grade pass/fail)

- a final exam (40%, grade pass/fail).

- a research project and its presentation (20%, grade pass/fail) 

Other requirements for final grade *

To pass, all bullets listed in the examination should be completed.
