A Modified Debugging Infrastructure to Assist Real Time Fault Injection Campaigns

André Fidalgo Gustavo R. Alves José Manuel Martins Ferreira

Fault injection is frequently used for the verification and validation of the fault tolerant features of microprocessors. This paper proposes the modification of a common on-chip debugging (OCD) infrastructure to add fault injection capabilities and improve performance. The proposed solution imposes a very low logic overhead and provides a flexible and efficient mechanism for the execution of fault injection campaigns, being applicable to different target system architectures

Engineering Education: Professional Demands

Clara Viegas Arcelina Marques Gustavo R. Alves

Engineering students' expertise relies on strong consolidated scientific and technological learning. However, more and more, it is their ability to adapt to new situations and competence in linking and using those knowledges that can make a difference. Also working under new environments and in multicultural teams. Their social skills and characteristics like teamwork, creativity, communication or leadership are already established as fundamental competences students must also develop during their education. Students have a heavy load when they approach their first professional experience. Their professional demands are here discussed by the hands of teachers who report their experiences as mean to help ease this issue. Also, some academic issues related to teaching curricular designs aspects are also addressed and invites readers to reflect upon their practices.

A flexible online apparatus for projectile launch experiments

Carlos Paiva Pedro Nogueira Gustavo R. Alves Arcelina Marques Pedro Guimarães

In order to provide a more flexible learning environment in physics, the developed projectile launch apparatus enables students to determine the acceleration of gravity and the dependence of a set of parameters in the projectile movement. This apparatus is remotely operated and accessed via web, by first scheduling an access time slot. This machine has a number of configuration parameters that support different learning scenarios with different complexities.

Engineering Education and Technological / Professional Learning

MDPI eBooks (2019)

Clara Viegas Gustavo R. Alves José García-Pe Arcelina Marques Francisco José García‐Peñalvo

The focus of this Special Issue is aimed at enhancing the discussion of Engineering Education, particularly related to technological and professional learning. In the 21^st century, students face a challenging demand: they are expected to have the best scientific expertise, but also highly developed social skills and qualities like teamwork, creativity, communication, or leadership. Even though students and teachers are becoming more aware of this necessity, there is still a gap between academic life and the professional world. In this Special Edition Book, the reader can find works tackling interesting topics such as educational resources addressing students’ development of competencies, the importance of final year projects linked to professional environments, and multicultural or interdisciplinary challenges.

On-Line Self-Healing of Circuits Implemented on Reconfigurable FPGAs

Manuel Gericota Luís F. Lemos Gustavo R. Alves José Manuel Martins Ferreira

To boost logic density and reduce per unit power consumption SRAM-based FPGAs manufacturers adopted nanometric technologies. However, this technology is highly vulnerable to radiation-induced faults, which affect values stored in memory cells, and to manufacturing imperfections. Fault tolerant implementations, based on Triple Modular Redundancy (TMR) infrastructures, help to keep the correct operation of the circuit. However, TMR is not sufficient to guarantee the safe operation of a circuit. Other issues like module placement, the effects of multi- bit upsets (MBU) or fault accumulation, have also to be addressed. In case of a fault occurrence the correct operation of the affected module must be restored and/or the current state of the circuit coherently re-established. A solution that enables the autonomous restoration of the functional definition of the affected module, avoiding fault accumulation, re-establishing the correct circuit state in real-time, while keeping the normal operation of the circuit, is presented in this paper.
