Arithmetic additive test pattern generators (AdTPGs) are now being proposed as an alternative to linear feedback shift registers (LFSRs) because of their reduced area overhead impact. As in the case of LFSRs, the compactness of the information required in memory and the test generation time needed to achieve a specified fault coverage level (FC) have a… (More)
The morphogenesis of the color pattern of animals is modeled with cellular automata. The cell-cell near neighbor interactions are taken into account and impose restrictions on the model. The allowed patterns are observed in reptiles, felines and fishes.
Built-in self-test (BIST) strategies require the implementation of efficient test pattern generators (TPG) which allow the excitation and observation of potential faults in the circuit. Arithmetic additive TPGs (AdTPG) allow existing internal datapaths to be reused to perform this operation without a penalty in the circuit area. AdTPGs are configured by… (More)
The morphogenesis of the color pattern of animals is modeled within the framework of a clonal model. The model takes into account the, sometimes conflicting, cell-cell and cell-background interactions. The color patterns of some reptiles and mammals are found to be consistent with the predictions of the model.
This paper presents and compares a set of experimental results on the measurement of power and energy consumed using an ammeter and a non-conventional capacitor-based method. A standard cell CMOS multiplier is utilized as a circuit under test. The paper shows, as main result, that the capacitor-based method allows the designer to obtain information… (More)
Crosstalk is one of the main limiting factors in the data rates achievable by digital subscriber line (DSL) systems, and several algorithms have been proposed to mitigate this impairment. In this paper, we compare the capacity of binders under different crosstalk-mitigating techniques. When computing capacity, we also compare two different power… (More)
—This paper describes a Copper Plant Manager concept for DSL first mile, which effectively enables performance monitoring, fault interpretation and dynamic link management. This concept copes with the nature and complexity of the underlying DSL network and presents a unified solution for controlling and managing its resources. An implementation of the CPM… (More)
