Uma Proposta para Detecção de Sobreposição de Sinais em Redes Sem Fio
Abstract
This paper presents a proposal for intersection signal detection. The proposed model is targeting to wireless networking and it is based on microwave transmission model (without any obstacles). The proposed model uses the circle mathematical model. Resumo. Este artigo apresenta uma proposta para a detecção de interseções de sinal em redes sem fio. O modelo proposto é baseado no modelo de transmissão de micro-ondas no ar (sem interferências) e usa como resolução o método matemático da intersecção entre circunferências.

Modern designs often contain a combination of a large number of standard cells and macro blocks. Traditionally large macro blocks are handled at the floorplanning level, after which their positions are fixed. The standard cells are then handled during the placement level. Current designs can have hundreds of large and medium sized macro blocks and a large number of standard cells. As a result, traditional floorplanning techniques cannot scale to this problem, both in terms of runtime and solution quality. Hence a technique is required to simultaneously handle this combination of placeable objects.In this paper, we present a combined placement and floorplanning approach for mixed-mode placement. We extend the efficient analytical placement algorithm FastPlace by integrating a simulated annealing based floorplanner to solve the global placement problem for mixed-mode designs. We also present an efficient and effective detailed placement algorithm to improve the wirelength of the global placement solution based on a greedy swapping heuristic.
