The course DIGITAL ELECTRONICS aims to study in depth the study and design of digital systems, both combinational and sequential. To this end, in addition to integrating the different systems that represent information digitally, students will develop their ability to analyse and design digital circuits.



As far as digital circuits are concerned, we will start from the already known techniques, based on wired logic, to evolve towards a design based on programmable logic. Later, Hardware Description Languages, such as VHDL, will be introduced, leading to the simulation and implementation of circuits in programmable logic devices, such as FPGAs. Also, in contrast, other digital devices such as microprocessor-based systems, their architecture and the digital memories of these systems will be briefly presented.



This subject is the basis for the development of many professional areas, such as industrial control systems, consumer electronics, automation of production processes, telecommunications, etc.



.Prerequisites:



Digital Electronics is a compulsory basic subject taught in the 1st term of the 3rd year of the Degree in Industrial Electronics and Automation Engineering, and in the 4th year of the Double Degree in Mechanical Engineering + Industrial Electronics and Automation Engineering. However, it requires the competences acquired in other subjects of the 2nd year, specifically in the subjects:

-Industrial Electronics

-Automation and control



.Contextualisation in relation to other subjects:



The basic concepts addressed by the Digital Electronics subject, as well as certain competences, knowledge and skills, are in turn necessary for other subjects taken in the 3rd year, such as:



-Digital Electronic Systems. Subject that gives continuity to Digital Electronics.

-Industrial Automation



Likewise, and for similar reasons, there are optional subjects in the following year of the Degree for which it is advisable to take this subject:



-Digital Control

-Advanced Control Techniques

COMPETENCIES of the Technology Specific Module of Industrial Electronics (TEEOI):



TEEOI3 Knowledge of the fundamentals and applications of Digital Electronics and microprocessors.

TEEOI6 Ability to design analogue, digital and power electronic systems (in particular digital electronic systems).

5.Apply the design methodologies for both hard-wired and programmable digital systems.

6.Efficiently use of the electronic design tools used in the laboratory.

Brief description of contents: Analysis and design of Digital Systems, .



Theoretical and practical content, more specifically, is developed through the following topics:



T0: Introduction

T1: Introduction to Digital Circuit Design and Implementation

T2: Hardware Description Languages

T3: Digital representation of information

T4: Fundamentals of Digital Electronics

T5: Combinational logic systems

T6: Sequential Logic Systems

T7: Implementation of digital circuits

T8: Memories

The way in which teaching is developed combines the expository mode with active methodologies based on cooperative learning, as well as inverted or flipped class. In addition, problem/project based learning (PBL/ABP) is used, whose scenarios will be real industrial applications that students will have to face collaboratively and propose, simulate and implement their own control solutions from the field of digital electronics.



The necessary competences and skills will be acquired both in the classroom sessions (M theory sessions + GA classroom sessions + GL Laboratory sessions) and in the non-classroom sessions.

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 35
  • Multiple-Choice Test (%): 10
  • Realization of Practical Work (exercises, cases or problems) (%): 25
  • Individual works (%): 5
  • Team projects (problem solving, project design)) (%): 25

. CONTINUOUS ASSESSMENT :



.. Block of Theory and Exercises:



For the evaluation of these contents, the results obtained from the following tests are considered:

- written tests, with questions and exercises: individual exams (1)

- individual tests, carried out during class time by the students present in the classroom.

- questionnaires in eGela, carried out outside the classroom

(1) for the calculation of the final mark for this block, it is essential to pass 30% of each of these written individual tests.



The final mark for this block of Theory and Exercises is obtained:

- written individual exams: 35%.

- tests: 10%.

- questionnaires: 5%.



.. Block of Laboratory Practices:



For the evaluation of these contents, the results obtained from the following tests are considered:

- Individual laboratory exam (2)

- Project solution to the proposed problem: Code, simulation and implementation of the project, validation with the teaching staff, report and other tasks.

(2) In order to calculate the final mark for this block, it is mandatory to pass at least the 50% in this test.

Both attendance at the laboratory sessions and the delivery of the project are compulsory.

In case of not having attended more than two laboratory sessions without the corresponding justification, it will result in the rejection of the continuous assessment, thus, the only option will be the final assessment, provided that the requirements to apply for it have been met.



The final mark for the Block of Laboratory Practices is obtained in this way:

- An Individual laboratory exam: 50%.

- A Cooperative project: 50%.



Students taking the subject in continuous assessment will obtain the mark of "no-show" when they meet the conditions established in the corresponding UPV/EHU regulations.



. FINAL EVALUATION:



Students who wish to refuse continuous assessment must do so under the conditions set out in the current regulations.



In this case, the assessment of competences will be by means of:

- the delivery and demonstration of a project (compulsory) and

- a FINAL EXAMINATION: on the official date of the exams period of the ordinary exams. This exam will consist of 2 tests, one for each block: 1 written exam with questions of Theory and Exercises, and 1 exam of Laboratory Practices.



. CONDITION FOR PASSING THE COURSE:



For passing the course is a prerequisite:

- to pass the exam related to the block of Theory and Exercises, and

- to pass the exam related to the block of Laboratory Practices (practical exam + project)



. FINAL QUALIFICATION:



The final mark for the course is obtained in this way:

-Block of Theory and Exercises: 50%.

-Block of Laboratory Practices (50% laboratory test + 50% project): 50%.

-If only one of the two previous blocks is passed, the FINAL mark will be a maximum of 4 (failed). The passed block will remain as such until the extraordinary exam.

-In the block of Theory and Exercises no parts are released, the whole block can be released.

-1 test (the exam or the project) can be released in the block of Laboratory Practices.



. HOW TO REJECT THE ORDINARY EXAMS:



Students who wish to refuse to the ordinary exams call must do so in accordance with the conditions and deadlines set out in the current UPV/EHU regulations.

In the extraordinary exams call, the same assessment criteria will be followed as those applied to students who apply for the FINAL EVALUATION in the ordinary exams call.



In this case, the assessment of competences will be by means of:

- the delivery and demonstration of a project (mandatory) and

- a FINAL EXAMINATION: on the official date of the exam period of the extraordinary call. This exam will consist of 2 tests, one for each block: 1 written exam with questions of Theory and Exercises, and 1 exam of Practices of Laboratory.



. CONDITIONS FOR PASSING THE COURSE:



For passing the course the prerequisites are:

- to pass the written individual test relative to the block of Theory and Exercises AND

- to pass the individual exam of the Laboratory Practices AND

- to deliver and to satisfactorily complete the demonstration of the project



. FINAL QUALIFICATION:
