85737 - Compliance Design of Automotive Systems M

Learning outcomes

The aim of the course is to provide the theoretical basis and the practical skills to design embedded hardware compliant with security standard (Hardware safety integrity requirements for the complete SIF and architectural constraints). In particular Power Supply Management and Computing Redundancy, will be deeply analyzed. In addition, high performance modular programming with respect to automotive and safety standards (AUTOSAR, ADSIL, SIL) and the automatic code generation using Matlab/Simulink will be considered.

Readings/Bibliography

Lecture notes, standards, and documentation of the software used.

Teaching methods

Lectures, laboratory activity in teams.

Assessment methods

Report on the laboratory activity and oral examination.
At the end of the laboratory activities each team of students must deliver a written report. After receiving an evaluation of their report, the students can individually take the oral examination.
The result of the oral examination accounts for 2/3 of the final mark, while the laboratory activity accounts for 1/3.

Teaching tools

Video projector, PC, MATLAB/Simulink, hardware-in-the-loop system.
