Design & Test of Fault-Tolerant E.S. for Aerospace App.


Let the student understands methodologies of design of systems fault-tolerant, redundancy by hardware and software, based on information and time.

Let the student understands physical mechanisms that cause errors or affect the reliability in environments with ionizing radiation.

Let the student understands methodologies of system testing.


Have basic knowledge of CMOS integrated circuit design, digital systems, information coding, and basic knowledge of reliability.

It is recommended to bring your own notebook to this course. In order to perform the SPICE simulations, LTSpice IV simulator will be use. It is available here. It runs in Windows; and in Mac and Linux, using Wine.

Dr. Fabián Vargas (PUCRS) obtained his Ph.D. Degree in Microelectronics from the Institut National Polytechnique de Grenoble (INPG), France, in 1995. At present, he is Full Professor at the Catholic University (PUCRS) in Porto Alegre, Brazil.

His main research domains involve the HW-SW co-design and test of system-on-chip (SoC) for critical applications, system design for radiation and electromagnetic immunities, and embedded sensor design for characterization, reliability and aging binning.

Among several activities, Prof. Vargas has served as Technical Committee Member or Guest-Editor in many IEEE-sponsored conferences and journals. He holds 6 BR and international patents, co-authored a book and published over 200 refereed papers. Prof. Vargas is associate researcher of the BR National Science Foundation since 1996.

He co-founded the IEEE-Computer Society Latin American Test Technology Technical Council (LA-TTTC) in 1997 and the IEEE Latin American Test Symposium – LATS (former Latin American Test Workshop – LATW) in 2000. Prof. Vargas received for several times the Meritorious Service Award of the IEEE Computer Society for providing significant services as chair of the IEEE Latin American Regional TTTC Group and the LATS. Prof. Vargas is a Golden Core Member of the IEEE Computer Society.
