Preliminary Concepts: (1 CFU) Introduction to the course, the definition of embedded system, its characteristics (efficiency, responsiveness, reliability). Hybrid systems: partitioning, HW / SW / analog. Use cases, actors, objects and classes, services and methods, static and dynamic parameters, sequence and collaboration diagrams. Agile methodologies. A car power window project: definition of objects and external interfaces, features, frequency, resolution, response time Specifications and Partitioning (1CFU) Writing and analyzing specifications of complex systems. Partitioning and interfaces. Analyses of compatibility, sufficiency and necessity of subsystems. Testing and verification. A car power window project: partitioning; definition and specification of interfaces; assignment of tasks to team members. Interfacing: (0.5CFU) Designing I/O interfaces; selection of components and documentation; simulations; compliance (typical and worst cases) Interfaces HW / SW: essential features, conversion between time-continuous and discrete-time, memory map. HW Implementation (1CFU) Designing schematics, simulation and PCB design State automata (1CFU) Definition of states and transitions; activities; events and guards. C and VHDL implementations. Car Power windows project: design of state automaton and implementation in C. SW implementation (0.5CFU) Writing SW drivers in C for microcontroller peripherals; writing code for operations; template classes and parameters; instance and classifier attributes. Concepts of VHDL implementations. Integration and testing of case study (0.5CFU) Assembly of the PCB designed; testing; integration with SW; final testing Documentation (0.5CFU) Report generation

Theoretical lessons; interactive developments; individual exercises; homeworks; development of a case study (car power windows); final project (optional).

Lecture notes available on the portal. Videorecording of lessons and didactical material in UML available on the portal and on the UML server. Any textbook on UML; e.g. “UML Distilled: A Brief Guide to the Standard Object Modeling Language (3rd Edition)”, Martin Fowler, ISBN 978-0321193681 Components data sheets Documentation of Visual Paradigm tools available on the WEB (http://www.visual-paradigm.com/) IAR documentation on tool available on Web (http://www.iar.com/website1/1.0.1.0/3/1/) SolidWorks documentation on tool available on Web KiCAD documentation on tool available on Web The students, divided in groups will receive and keep for the whole course duration an MSP430 development board from Texas Instruments (to be confirmed depending on COVID-related constraints)

Exam: Written test; Group project;

Alternatively: - Exam: written test, individual essay (typically: given some high level specs, the student shall determine the system and detailed architectures, verify its completeness and to write the code for a few digital, analog or SW objects). - Alternatively, a group design essay (typically, a complete development of a real commercial system, either chosen by the group or proposed by the teacher). The first draft of the essay will be orally discussed by the group, allowing additional time to correct the essay report. The vote will also take into account the evaluation of efforts and documents drawn up during homeworks and during the classes. Further information: Written exam: optional, duration 2h; possibility of using any type of material, calculator, free access to Internet, highest score: 30L Group essay: design activity with final report, in groups. Discussion of the first release of final report. Additional time to improve the report based on discussion. Highest score: 30L, Additional marks can be gained with the optional homework.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
