Electronics project at LiTH
Course responsible Tomas Svensson

• Course start Spring 2003.

Goals

• To increase the practical engineering parts on
  the Y line.
• To stimulate the students "design spirit".
• To give a good knowledge in using VHDL
• To bring experience in developing microcontroled
  machines
• To train the use of structured design methods
• To give a good practice in project work
• To give understanding in the use of a project
  model
• To understand the importance of communication in
  a project
• (learning objectives 2.1-2.4, 3.1, 3.2, 4.3-4.6
  as defined in
• CDIO syllabus)

The project task

• The students shall, in groups of 6 persons,
  design a relatively
• advanced computer controlled machine.
• The design includes a number of computers,
  discrete digital
• circuits, programmable logic, analogue
  interfaces, different displays
• and a number of sensors.
• The design will be built on a circuit board with
  wiring technique.
• Maximum 1000 hours per project

Work in the Project group
10
VHDL labs

• Each lab is defined by a LIPS requirement
  specification.
• The lab group consists of all 6 project members!
• There are 2 labs
• Design of a system for serial data transfer via
  an optical link
• Design of a presentation system with a VGA
  monitor
• Both labs are divided into 2 design tasks, each
  task is done
• by 3 students. A mini project!
• -gt the project group will be established
• -gt see 2 LIPS requirement specifications
• -gt repetition of earlier theory, introduction to
  project work

11
Starting up the project.

• The project team is formed by the students
• Each team selects a student as project manager
• Each student shall have a defined
  responsibility documentation,
• hardware design, software design, test,
  delivery
• the team selects a project (or propose an own
  project)
• the team receives a project directive with
  common requirements
• (the common requirements force a modular
  design)

Week 8 to 13 in the project
During
MUXEN is open 24 hours a day
18
Muxen project lab

• Access 24 hours/day by magnetic card
• Each group has their own place with a computer
  and
• a logic analyser
• Each group has a place where tools etc. can be
  locked in
• There are 5 extra resource places
• Common area for discussions
• A conference room
• Component service
• The time must be planned, all students can not
  be there at
• the same time
• Each group is allocated 2 hours supervision per
  week
