ELEC ENG 2100 - Digital Systems

North Terrace Campus - Semester 1 - 2021

This course develops engineering capabilities pertaining to the design of digital electronic systems. Designs for contemporary implementation technologies are expressed using circuit schematics and SystemVerilog, at levels of abstraction from CMOS transistor circuits up to processor microarchitecture. System architecture, microarchitecture and interfacing concepts are developed through an extended case study of a commercial microprocessor. The course operates as a flipped classroom with students attending weekly 2-hour tutorials. Preparatory lectures, reading and exercise questions are completed before tutorials. Tutorial problems are more open-ended and typically require discussion in small groups, practical design, simulation and implementation using computers and reconfigurable logic circuits. Students also undertake a group research exercise on a question related to the future of digital electronics technology.

    Online Learning
    This course uses the MyUni web site. All announcements are posted on MyUni. Recorded slide show presentations, practice and tutorial questions, and other resources are available on MyUni. The gradebook is used to communicate marks. The research assignment is submitted using MyUni. A discussion board is available for course-related discussion.
  • Learning & Teaching Activities
    Learning & Teaching Modes
    Tutorials: the course uses a flipped classroom with an emphasis on weekly 2-hour face-to-face tutorials. Students prepare for tutorials by reading sections of the textbook, watching pre-recorded lectures, and attempting preparation exercises. During tutorials, teaching staff spend time with each student individually to help explain difficult concepts. Tutorial time is also spent working as individuals on exercise problems and in small groups on design problems.

    Recorded Slide Shows: wherever possible the slide shows follow the structure, terminology and notation of the course textbook. Slides and recoded presentations are available prior to tutorials and, where material outside of the scope of the textbook is presented, detailed notes are provided. Students are expected to read sections of the textbook, watch the side presentations and attempt some exercise problems in preparation for tutorials.

    Small Group Discovery Experience
    The Research Assignment is a small group discovery experience. Students form small groups and choose a topic of interest related to future electronic technology. Groups meet twice with an academic mentor who helps them refine their research question and find relevant resources. Each group prepares a short report that includes a survey of published results from high-quality academic sources. The reports should focus on a recent development in a technology and show how this relates to the evolution of that technology.
  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course.


    Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.

    To support the changes to teaching, the following revisions to assessment have been made:-

    We will run Tests 2 and 3 in weeks 7 and 10, respectively, as scheduled before.

    Here is part of the latest message form the University regarding the final exam: "... The University will not hold exams as usual this
    semester. Instead, all invigilated exams requiring personal attendance will need to be changed to alternative assessments - without invigilation, administered through MyUni. Example alternatives might include open-book exams, online tests, or written reports." Therefore, I will announce the alternative assessment late next week and explain howwe will run it.
    Assessment Related Requirements
    The examination is a hurdle requirement. It is necessary to achieve at least 40% in the exam. If this is not achieved, the total course mark will be limited to a maximum of 49. Further details of hurdle requirements are explained in the University's Assessment for Coursework Programs Policy.
    Assessment Detail
    Tutorials: students maintain an exercise book in which they record tutorial preparation and the work completed during tutorials. This is assessed during tutorials on the basis of the student having attempted and then corrected prescribed exercises.

    Tests: 40 minute tests are held in weeks 4, 7 and 10.  

    Research Assignment: students work in a small group to write short report on an emerging electronic technology. Groups are assigned a member of staff to advise them on their topic. The report should draw upon research published in high-quality sources. It is due in week 11.

    Exam: a 2-hour examination is held at the end of the semester. 

    Submission
    Tutorial preparation and tutorial exercises are marked during the tutorial sessions with verbal feedback given immediately. In Tutorial 3, for example, the exercises for Tutorial 2 and the preparation for Tutorial 3 are marked.

    Students can expect the marks from their continuous assessment activities to be available on MyUni within two weeks of the activity.

    The report for the research assignment is due in week 9 and will be submitted on MyUni (and may use TurnItIn).

    In keeping with the University’s policy on Modified Arrangements for Coursework Assessment, students whose capacity to demonstrate their true level of competence in a continuous assessment task was seriously impaired because of approved medical, compassionate or extenuating circumstances will be offered the following modified arrangements.
    • For tutorials: an extension of the deadline.
    • For a test: by excluding the assessment in question and proportionally scaling up the student’s marks for work completed during the course.
    • For the research assignment: an extension of the deadline.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

    The following changes have been made for 2019 in response to last year's feedback

    • created more space at end of course
      • reorganised tutorials a bit
      • moved research assignment forward
    • added Q&A workshops
    • refreshed content
      • upgraded lab hardware
      • migrated from Verilog to SystemVerilog
      • software now in CATS
    • relocated tutorials to CATS
  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
