Risultati di apprendimento attesi

The course aims to introduce students of the Master of Science in Electronic Engineering in the issues related to the design and development of electronic systems. The term "system" is intended as a set of passive and active electronic components, even complex, suitably interconnected and resident on one or more printed circuit boards. The course also aims to illustrate the design flow that allows to pass from the transistor level to complex electronic system.

Knowledge and understanding
The course will focus on the main architectures of arithmetic circuits (data path) and on the methodology to design the control path of an integrated digital electronic system. Moreover, the design issues related to the interface of an integrated circuit to the "outside world" are addressed. At this purpose, the design and technology of printed circuit boards and passive components will be considered.

Applying knowledge and understanding
At the end of the course the student will be able to: 1. design the data path and the control path, also through the use of VHDL, of a digital electronic system; 2. design a multilayer printed circuit board and the power/ground distribution network; 3. design at the system level a complex electronic system also through the use of microcontrollers and FPGAs.

Making judgements
Starting from technical specifications, the student will be able to design electronic systems using different levels of abstractions. Numerical exercises, computer simulations and the development of a design projects will refine the making judgement skill.

Communication skills
The student will improve the technical language of electronic systems and will be able to interact with colleagues of a teamwork to discuss the proper solutions to a specific design problem. To this aim, during the laboratory lessons, students will be grouped in small teams. The reports and the oral exam will also help to refine technical language and communication skills.

Learning skills
Students can broaden their knowledge of electronic systems through the study of recommended textbooks or scientific papers published on specialized journals and through the ideas offered by the seminars organized within the course.

Modalità di svolgimento dell'insegnamento

The course includes 42 hours of lectures and 30 of CAD/CAE-assisted numerical exercises. Seminars held by researchers and designers from industries operating in the electronics sector will be also organized.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the program planned and outlined in the syllabus.

Prerequisiti richiesti

Students should have prior knowledge of basic digital electronics and transmission lines.

Frequenza lezioni

Attendance is not mandatory, although strongly recommended. Attending and actively participating in the classroom activities will contribute positively towards the overall assessment of the oral exam.

Verifica dell'apprendimento

Modalità di verifica dell'apprendimento

Learning assessment is verified through the final exam. This consists of an oral exam and the evaluation of 4 practical homeworks to be submitted during the course (60% of the final grade). The students who will not be able to submit the 4 homeworks during the course will be assigned a project that will be worth 60% of the final grade. The project report must be delivered to the teacher's email address at least one week before the beginning of the first session of exams. Assessment criteria of the homeworks/project include: depth of analysis, correctness and originality of the design solutions, ability to justify and critically evaluate the adopted technological solutions, clarity.

The oral exam consists of three questions on three course topics. In the answers, the student must demonstrate adequate understanding, mastery of the topics discussed and clarity of presentation. The average duration of the oral exam is 40 minutes. The oral exam is worth of 40% of the final grade.

Learning assessment may also be carried out on-line, should the conditions require it.

A garanzia di pari opportunità e nel rispetto delle leggi vigenti, gli studenti interessati possono chiedere un colloquio personale in modo da programmare eventuali misure compensative e/o dispensative, in base agli obiettivi didattici ed alle specifiche esigenze. È possibile rivolgersi anche al docente referente CInAP (Centro per l’integrazione Attiva e Partecipata - Servizi per le Disabilità e/o i DSA) del proprio Dipartimento.
