Sobre

Licenciei-me em Engenharia Eletrotécnica e Computadores na Faculdade de Engenharia da Universidade do Porto em 1985. Desde essa data entrei na Faculdade de Engenharia como Assistente Estagiário e ao mesmo tempo no recém criado INESC do Porto, onde nos primeiros anos desenvolvi trabalho na área da Investigação Operacional, Computação Gráfica e Microeletrónica, que foi o tema do meu projeto final de curso. Durante vários anos estive integrado no grupo de CAD e Microeletrónica do INESC Porto e mais recentemente associei-me ao atual Centro de Robótica e Sistemas Autónomos onde tenho colaborado na conceção e desenvolvimento de sistemas robóticos marinhos, em particular veículos autónomos de elevada autonomia. 

Concluí o Doutoramento em Engenharia Eletrotécnica e Computadores em 1998, na área da conceção e desenvolvimento de sistemas computacionais reconfiguráveis. Atualmente sou Professor Associado na Faculdade de Engenharia da Universidade do Porto onde tenho lecionado nas áreas de projeto de sistemas digitais para tecnologias microintegradas, microeletrónica digital e circuitos elétricos. A minha área de especialização principal situa-se na conceção de sistemas computacionais dedicados e sua implementação em plataformas digitais reconfiguráveis baseados em dispositivos digitais FPGA (Field-Programmable Gate Array).

PSION plus : Combining Logical Topology and Physical Layout Optimization for Wavelength-Routed ONoCs

IEEE TRANSACTIONS ON COMPUTER-AIDED DESIGN OF INTEGRATED CIRCUITS AND SYSTEMS

Abstract
Optical networks-on-chip (ONoCs) are a promising solution for high-performance multicore integration with better latency and bandwidth than traditional electrical NoCs. Wavelength-routed ONoCs (WRONoCs) offer yet additional performance guarantees. However, WRONoC design presents new EDA challenges which have not yet been fully addressed. So far, most topology analysis is abstract, i.e., overlooks layout concerns, while for layout the tools available perform place and route (P&R) but no topology optimization. Thus, a need arises for a novel optimization method combining both aspects of WRONoC design. In this article, such a method, PSION+, is laid out. This new procedure uses a linear programming model to optimize a WRONoC physical layout template to optimality. This template-based optimization scheme is a new idea in this area that seeks to minimize problem complexity while keeping design flexibility. A simple layout template format is introduced and explored. Finally, multiple model reduction techniques to reduce solver run-time are also presented and tested. When compared to the state-of-the-art design procedure, results show a decrease in maximum optical insertion loss of 41%.

Thus, a need arises for a novel optimization method combining both aspects of WRONoC design. In this paper such a method, PSION, is laid out. When compared to the state-of-the-art design procedure, results show a 1.8x reduction in maximum optical insertion loss.

An Alternative SNR Computation Method for ADC Testing

Publicação
2019 XXXIV CONFERENCE ON DESIGN OF CIRCUITS AND INTEGRATED SYSTEMS (DCIS)

Abstract
An alternative approach to compute the signal to noise ratio of analogue to digital converters based on the computation of the cross-correlation coefficient of the captured response is proposed here. It is shown, after simulation and experimental results, that this approach allows obtaining good accuracy results with the added advantages of not requiring coherent sampling and high purity sine wave stimuli.
