The course is taught in English. This class is intended to introduce students to the design and analysis of embedded electronics systems that interact with physical processes. Applications include medical devices, consumer electronics, automotive systems, process controls, manufacturing . A major theme of this course will be the skill to design an electronic system, starting from the technical specifications through the circuit analysis up to the final printed circuit board design. Testing procedures and failure analysis will be also described. A professional Electronic Development Aids (Cadence/Allegro) will be used to design the circuit, to simulate it and to verify its behaviour. Signal integrity aspects will be also evaluated. A case study will be used from the design up to the hardware testing in a final laboratory. Each student will also develop and discuss a homework selected at the beginning of the semester. A final technical report will describe each aspect of the project. The PCB, organised using Gerber files will be submitted to a professional manufacturer (Eurocircuit) to be checked and, in some cases, implemented.

The course enables students to acquire the knowledge and ability to apply basic and advanced design techniques for embedded electronic systems. They will be able to investigate every side of board-level design, starting with the basics of design trends, rules, signal integrity up to the project documentation. At the end of the teaching module the student will get the following competencies and abilities: - Knowledge of the problems related to embedded electronic systems design from specifications to implementation through the simulation of their behavior - Ability to describe the project (requirements, documentation, manuals) - Knowledge of international standards and rules ( EMC, user interface, reliability) - Knowledge of technologies, design flow, design rules for Printed Circuit Boards , and ability to use related CAD tools; - Knowledge of material properties, packaging, component placement, thermal effects, and ability to develop design taking into account these issues. - Knowledge of applied EMC/EMI and ability to consider them in the design; - Knowledge of basic concepts of manufacturing aspects (ergonomy, quality, certification)

Good Knowledge of the basic CMOS characteristics, logic circuits, microprocessors, microcontrollers and memories. Basic understanding of the frequency domain representation of linear systems. Basic knowledge of analog and digital electronic circuits.

A CAD tool (Cadence) able to allow students to draw the circuit (ORCAD), to simulate it (PSPICE), to test the circuit connections (DRC), to give an intermediate form of the circuits and the connections (NETLIST), to produce the final PCB (ALLEGRO) gerber files is given to every students free of charge for one year. It will be used to develop the exam project using the student personal computer both for the remote exam and for the the traditional exam.

Theory: Theoretical aspects of how a Printed Circuit Board is organised. Multi-layers structures, layout, IC placing, signal routing, Design Rule Checking, Net-list, Gerber files, Manufacturer report, Final technical Report. Each aspect of a circuit project is described and analysed. Practice: the arguments of the course go with a series of practical and numerical exercises related to technological aspects of PCBs. Laboratory: a case study will be presented, starting from the CAD design, simulation and analysis up to the final PCB and testing of the circuit. The PCB, organised as Gerber files, will be submitted to a professional manufacturer to see the final Design Rule Check. Homeworks: each student will choose one argument from a list of topics related to advanced aspect of the Electronics Systems Design. He will receive material (scientific and technical papers, datasheets and so on) and will organise a small presentation for his fellows. The homework will be organised as a circuit (ORCAD), the Design Rule Check, the Netlist and the final Gerber Files which will be submitted to a manufacturer to be checked. Selected circuits will be implemented (optional) and will replace the final common practical exam. Students must choose the exam format by the end of October.

... The exam's goal is to verify the skill of the students to develop the project of an embedded electronic system. Theoretical issues will be checked by means of a final written test. Practical skills will be checked by means of individual or group (maximum 2 students) personal projects or team (thesis) projects. The final exam is organised with the following rules: 1) a brief (30 minutes) written theoretical section where 7 questions with closed answer with the weight of 0.47 (14/30) on the final score; minimum 4/7 answers should be right. No text (books, notes and so on) will be allowed during the test. 2) a 120 minutes written practical exam on the whole subjects (classes and practises) with the weight of 0.34 (10/30) on the final score; notes and books are allowed. A project will be proposed and each student has to use the CAD tools to produce the whole project (schematic, DRC, BOM, Netlist, Gerber files, technical report) ; 3) alternative to 2). An optional individual (or group, maximum 2 students) electronic project (assigned at the beginning of the semester) will be presented and evaluated with the weight of 0.5 on the final score (maximum 15/30). After 2 months (before XMAS vacations) each group will present 4 items: power point presentation, technical report, project schematic with BOM, Gerber files validated by a manufacturer. If approved the groups will receive comments, suggestions and temporary evaluations immediately after the XMAS vacations. They will have time up to the end of the course (January 20) to apply the required changes. If not approved they will leave the project and will attend the regular exam, part 2). 4) alternative to 2 and 3. Selected projects (teams, thesis) will be implemented and checked in the laboratory by the students (optional, maximum 19/30). If not approved they will leave the project and will attend the regular exam, part 2).
