Goals Revisited

• Design and Test of SOC complexity, multiplicity
  of concepts, methods, algorithms and tools
• It is crucial
• to develop in students and engineers creativity,
  skills of critical thinking, problem solving and
  decision making,
• to give them experience of developing new
  knowledge through experimental or theoretical
  research in labs
• To support this goal, a new conception of
  teaching research will be developed and shared
  between partners

9
Goals Revisited

• To find solutions for problems - will be the task
  of the laboratory research
• The students should not be asked
• to carry out boring measurements,
• to press simply on buttons for getting results
  as a confirmation of what they already know
• Instead,
• they have at their disposal a set of tools,
• they have to plan and carry out experiments to
  find answers for questions and complex problems

10
Rethinking the Task 3.2

• Task 3.1. Courses
• Task 3.2. Teaching, training and research
  environment
• Internet based living pictures for training
  (WP8)
• Education applets
• Learning (training) applets
• Tool development for SW based research (WP3)
• Interfaces for joint use of tools
• Educhip for HW based research (WP9)
• Task 3.3. Research scenarios
• Task 3.4. Dissemination (tutorials, workshops,
  courses)

11

Example Research Scenario
Hybrid BIST

• Combining
• on-line generated pseudo-random patterns
• with pre-generated and stored test patterns
• Problems
• To find the best characteristics for test
  generator (PRPG)
• To find the best level of mixing pseudo-random
  test and stored test as the tradeoff between
  memory cost and testing time

Main achievemetns

• Co-operation between partners with the goal to
  develop new courses and laboratory tools resulted
  in intensive joint research with several joint
  publications
• For better coordination of the work in WP3, three
  WP3 meetings were organized in Brno, Tallinn and
  Bratislava
• Two joint tutorials on Digital/Analog Test were
  carried out in Tallinn with involving the
  partners FEISTU, IISAS, TTU, TULC, VSTU, and WUT
• Both had a great success, attended, by 25/34
  participants
• The tutorials will be repeated in 2003 twice in
  Ukraine, in Czech Republik, Slovakia and partly
  also in Germany and twice in Sweden

20
Main achievemetns

• To increase the synergy of the whole project,
  tight links were created between 3 WPs - WP3 and
• WP8 - to create a basis for distance learning,
  and
• WP9 - to improve the HW based experimental
  research teaching
• Based on the intensive cooperation (IISAS, TTU,
  TULC, WUT) the conception of Task 3.2 of tool
  development was extended with the goal to develop
  an advanced research training environment
  involving
• new low-cost tools,
• advanced distance learning technologies and
• educational HW based laboratory basis (using
  EduChip)
• Based on this environment, new research training
  scenarios will be developed during the
  second/third project years

21
Main problems

• Overlaps in proposed courses, tutorials and other
  events. This makes coordination of this WP more
  difficult
• Partners are looking for ways of better
  coordination of the work
• Examples
• Action AGBOT to better motivate the cooperation
• Developing jointly research training environment
  as the result of cooperation between WP3, WP8 and
  WP9
• For joining efforts in developing new research
  scenarios based on this environment, new links
  and interfaces between partners tools should be
  created

22
Concluding Remarks

• We have to look for more intensive cooperative
  activities, local actions are less important
• Joint courses, tutorials
• Joint tool environments
• Joint research scenarios
• Defect oriented test (WUT, IISAS, TTU)
• Hybrid BIST (WUT, IISAS, TTU)
• Design for testability (TTU, TULC), etc.
• Joint materials AGBOT
• The goal for 2003 Hands-on lab courses for
  partners with partner tools are the way to
  cooperation and to creation of joint research
  scenarios
