Conoscenze e abilità da conseguire
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.

Testi/Bibliografia
Dispense del docente, standard e normative, documentazione dei tool software utilizzati.
Metodi didattici
Lezioni frontali, attività di laboratorio a gruppi.
Modalità di verifica e valutazione dell'apprendimento
Relazione sulle attività di laboratorio e esame orale.
Al termine delle attività di laboratorio ogni gruppo di studenti dovrà consegnare una relazione scritta. Dopo aver ricevuto la valutazione del proprio lavoro, i componenti di ogni gruppo potranno accedere individualmente all'esame orale.
Il risultato dell'esame orale conta per i 2/3 of del voto finale, mentre le attività di laboratorio contano per 1/3.
Strumenti a supporto della didattica
Videoproiettore, PC, MATLAB/Simulink, sistema hardware-in-the-loop.
