1 CAD Tools Utilized in Microelectronic IC Design Education in the University of Oulu Janne Aikio, Timo Rahkonen University of Oulu, Finland Department of Electrical Engineering and Infotech Oulu

2 Content Introduction CAD tools in EE education in University of Oulu CAD education in other finnish Universities Computer Aided Circuit Design course in Oulu Conclusions

3 Introduction The importance of CAD tools in engineering is undeniable =>Utilization of CAD tool in microelectronics education is increasing Multitude of CAD tools and little support causes problems Students should not believe the simulation results without a doubt => Hand calculation skills are needed!! CAD education is important but not well organized in all universities

12 CACD - Preliminary Knowledge Survey 1. What method would you use to simulate a) Frequency response of a linear circuit (65%) b) Noise of a linear circuit (10%) c) Operation point of a nonlinear circuit (45%) d) Transient response of a nonlinear circuit (50%) e) Harmonic distortion of a nonlinear circuit (-) f) S-parameters of an RF circuit (20%) 2. Draw a mind map about Computer Aided Circuit Design 3. Make a list of software you have or are using for mathematical computation or circuit design (EDA-tools). Estimate your know how (1-5) and how often you use them (1-5). 4. Expectations of the course.

15 Conclusion CAD tools are commonly used in microelectronics education but the support or CAD education is not very well organized => Students SHOULD know what method to use, how it operates and what are the restrictions The CAD education varies widely in the finnish universities => CAD tool development and education almost disappeared from Aalto University Research and industry needs reflects in the education => In Oulu we have CAD orientated research, which keeps the topic important
