VLSI DIGITAL DESIGN
Learning outcomes of the course unit
Knowledge and understanding.
advanced skill on digital design, with emphasis on VLSI system and low-power design.
Applying knowledge and understanding: being able to develop autonomously the design of a digital system of realistic complexity.
Making judgements: evaluating different design options and making choices based on functional and performance specification. Communication skills: being able to communicate in effective and concise fashion one’s own design activity, also in a team-working environment.

The course includes:
- Oral lessons
- Lab work, which in turn includes:
- Asssisted design activities, under teacher guidance, aimed at hardware and software tools training
- Autonomous design work, by teamworking with teacher assistance
Assessment methods and criteria
The final examination consists of two parts: presentation of design activity and oral examination. The presentation of design activity (carried out on teacher’s assignment) consists of a group presentation, with audiovisual support. Presentation quality and effectiveness contribute (together with technical contents) to the final evaluation. Oral examination is carried out individually and is related to theoretical topics included in the program. Both parts have similar weight in the final marks assessment.
