  7. Tool development in 2003 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  8. 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 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  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 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  10. Rethinking the Task 3.2 • Task 3.1.Courses • Task 3.2.Teaching, training and researchenvironment • 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) Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  11. Cooperation in Tool Development Defect-Oriented Test • TTU: Defect-oriented ATPG and Fault Simulator • IISAS: Genetic algorithms based defect-oriented ATPG • LPU/WUT: Cell-oriented Defect/Fault Analysis BIST • TTU: BIST Quality Analysis • TULC: Tools for test generation and BIST • TTU: Hybrid BIST Cost Optimization High-Level ATPG • TTU: Hierarchical ATPG • KTU: Test Generation for testing algorithms Other new tools: • BSU: Test Generation and Analysis for Functional Switching • TTU: Tools for Fault/Design Error Diagnosis • VSTU: Test and Diagnosis of Analog Circuits Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  14. 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 Example: ResearchScenario Hybrid BIST: SoC ROM . . .

  16. New Courses in 2002 In progress (4): Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  17. Events planned for 2003 International events (9): Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  18. Events planned for 2003 Local events: Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  19. 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 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  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 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  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 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003

  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 Annual Review Meeting, Lviv, Ukraine, February 14-15, 2003
