Award: Best paper selected : "Adaptive Logical Control of RF LNA performances for efficient energy consumption"
on 18th IEEE/IFIP International Conference on VLSI and System-on-Chip, Madrid, Spain, (pp. 161-166)
Abstract : This paper presents a new approach for controlling power consumption in RF devices. The approach is based on the definition of application-dependent performance modes for power hungry RF circuits and a logical control strategy that adjusts the power supply of each circuit to the mode required by the application. The control strategy uses embedded sensors, a recursive parameter identification approach and regression models for performance prediction, while demanding minimum embedded resources for computation. The control strategy is robust with respect to circuit parametric deviations due to the manufacturing process or ageing mechanisms. The strategy is illustrated for the case of an RF LNA using envelope detectors as embedded sensors. Simulation results of the control strategy at the transistor-level illustrate the energy savings that can be obtained for an example application.

Award: Paper selected: ISIS: Runtime Verification of TLM Platforms by L. Ferro and L. Pierre (VDS Group)
The context of this paper is the dynamic assertionbased verification (ABV) of TLM SystemC models. We have developed a methodology for checking temporal properties during the SystemC simulation. The assertions are expressed in the PSL language, including the possibility to use its modeling layer, and the method supports timed as well as untimed TLM descriptions. It is implemented in a prototype tool called ISIS. We describe its principles and technical characteristics, and we report various experimental results

IEEE European Test Symposium 2009, Best Paper Award, H. Stratigopoulos and S. Mir.

Award: Paper selected: "Defect Filter for Alternate RF Test” by Haralampos-G. Stratigopoulos, Salvador Mir, Erkan Acar and Sule Ozev.
Alternate RF testing is a very promising candidate for replacing the costly standard specification-based approach. The defect filter in the alternate test flow is a crucial preparatory step for the overall success of alternate test. In this paper, we present a novel nonlinear defect filter based on an estimate of the joint probability density function of the alternate measurements. The construction of the filter does not require a defect dictionary and can accommodate any underlying density without needing any prior knowledge regarding its parametric form.


ASAP'09 Best Paper Award to Xavier Guérin and Frédéric Pétrot

Award: Paper selected: A System Framework for the Design of Embedded Software Targeting Heterogeneous Multi-Core SoCs by Xavier Guérin and Frédéric Pétrot
Embedded appliances designers rely on Multi-Core System-on-Chips (MC-SoC) to provide the computing power required by modern applications. Due to the inherent complexity of this kind of platform, the development of specific system architectures is not considered as an option to provide low-level services to an application. Hence, the software is built either from scratch - when the software's requirements are not too high - or over a general-purpose operating system, leading to performance and memory usage trade-offs. Our contribution is a component-based system framework that provides high-level system services for embedded software applications with few impacts on the memory usage and final performances, thanks to strong interfaces that enable the reuse of existing software elements and facilitate the support of multiple hardware platforms.
