- 9 CFU class.
Methodological knowledge: elementary knowledge of basic combinational and sequential logic circuits, of the logic circuit design procedure, of the microcontroller and of some programmable logic devices; use of the basic knowledge acquired in this course for continuing education in the field of electronic digital systems.
Professional skills: ability to design simple digital circuits, at logic level; ability to use basic CAD applications for digital systems, requirement analysis.
12 CFU class. Please add:
Professional skills: knowledge of microcontroller elements, design interface (IDE) and C++ language applied to the ArduinoUno platform. - Prerequisites
- To undergo the final exam of the class you do NOT NEED formal pre-requirements. However, the student is required to have assimilated all the basic issues taught in “Computer Science Basis and lab”, “Circuit Theory” and “Computer architecture and operating systems”.
Students attending the laboratory should have taken the course on safety in working places. - Teaching methods
- The lectures are organized as follows:
- face-to-face lectures on all the issues of the extended program;
- classworks for the preparation of the final exam.
12 CFU class. Please add:
- laboratory activity dedicated to microcontroller programming in C++ language. We foresee that during each laboratory lecture the students are distributed over 10 lab benches equipped with personal computers and laboratory instrumentation. The students will attend about 16 guided lab classes, 2 hours each. Most of the lab classes will be concluded with a team-classwork: each team will be asked to describe the lab work, both in text form and graphically. - Other information
- Every modification of the information reported in this syllabus will be communicated to the students and added to the web pages dedicated to this course at the web page https://www.unistudium.unipg.it/ .
- Learning verification modality
- 9 CFU class.
The exam consists of a written assignment, max. score = 32/30max allowed time 120 min. Le classwork is normally made of 2 sections on the Unit #1 (Logic networks) and n.1 section on Unit #2 (Basic concepts of digital electronics)
1) The first exercise (max score=10) asks the student to design a combinational logic circuit such as, for example, the selection (or docoding) logical circuit of a memory system.
2) The second exercise (max score=11) proposes the design of a simple synchronous state machine. It is divided in two sections, the first one proposes the design of a state machine, the second one is dedicated to K maps and the extraction of equations from a K map.
3) Follows a single open question (max score=10), related to the fundamental concepts of digital electronics.
12 CFU class.
* The positive evaluation of the lab assignments requires the students attend at least 75% (60% in 2020-21 due to pandemia and consequent restrictions) of the labs and produce at least the pertaining team lab classworks. Therefore the final score is the same of the 9 CFU exam and will be recorded only after attaining the green light on the laboratory attendance.
The final score can only be registered provided the lab exam is passed. - Extended program
