Full textThe context of this thesis is the functional verification of complex integrated circuits.The objective of our work is to create a seamless verification flow joint to the design flowand based on a proved technique called Assertions-Based Verification (ABV). The mainchallenge of TLM to RTL refinement is the disparity of these two domains : at TLM,communications are modeled as atomic function calls handling all the exchanged data.At RTL, communications are performed by signals according to a specific communicationprotocol. The proposed temporal transformation process is based on a set of formaltransformation rules. We have developed a tool performing the automatic refinement ofPSL specifications. As for design refinement assertion refinement is not fully automated.Temporal and structural information must be provided by the user, using an ergonomicinterface. The tool allows the generation of assertions in RTL but also hybrid assertions.Little work has been done before in this area, and the proposed solutions suffer from severerestrictions. To our knowledge, our prototype is the first tool that performs a temporaltransformation of assertions based on the formal semantics of a standard specificationlanguage (PSL)

Full textThe fast evolution of microelectronic technologies and their ever-improving integration capacities made possible the appearance of a new generation of components on the market: the “System-on-Chip”. The complexity involved when designing these new components and the permanent need to increase the productivity of the system design process in order to reduce the time-to-market leads designers to raise the level of abstraction of their simulation models. Thus, our goal is to provide a set of high-level models and software tools enabling designers to conduct very early in the design process the HW/SW co-simulation of systems. All models developed in this thesis are integrated to the SystemC simulation library of CoFluent Design's CoFluent Studio™ software environment. This work was done in the context of the MEDEA+ A502 MESA project

Full textEmbedded systems-on-chip (SoC) invade our daily life. With advances in semiconductor technology, these systems integrate more and more complex and energy-intensive features which generate increasing computation load and memory size requirements. While the complexity of these systems is a key trend, energy consumption has emerged as a critical factor for SoC designers. In this context, we have studied a modeling transactional level approach allowing a description of a clock tree and its management structure to be associated with a functional model, both described at the same abstraction level. This structure developed in a separation of concerns approach provides both the interface to the power consumption management of the hardware components and the application software. All the models developed are gathered in a C++ ClkArch library. To apply to a SystemC-TLM architecture model a clock tree intent with its control part, we propose a methodology based on three steps: specification, modeling and simulation. A verification step based on simulation is also considered using contracts of assertion type. This work aims to build a modelling approach on current design tools. So we propose a representation of a clock and power management structure in the IP-XACT standard allowing a C++ description of the SoC power management structures to be generated. Finally, a power management strategy based on the global functional states of the components of the system architecture is proposed. This strategy avoids local decision-making unsuited to optimized overall power/energy management

Full textIn response to the growing demand for performance by a wide variety of applications (eg, financial modeling, sub-atomic simulation, bioinformatics, etc.), computer systems become more complex and increase in size (number of computing components, memory and storage capacity). The increased complexity of these systems results in a change in their architecture towards a heterogeneous computing technologies and programming models. The harmonious management of this heterogeneity, resource optimization and minimization of consumption are major technical challenges in the design of future computer systems.This thesis addresses a field of this complexity by focusing on shared memory subsystems where all processors share a common address space. Work will focus on the implementation of a cache coherence and memory consistency on an extensible architecture and methodology for validation of this implementation.In our approach, we selected processors 64-bit ARM and generic co-processor (GPU, DSP, etc.) as components of computing, shared memory protocols AMBA / ACE and AMBA / ACE-Lite and associated architecture "CoreLink CCN" as a starting solution. Generalization and parameterization of this architecture and its validation in the simulation environment GEM5 are the backbone of this thesis.The results at the end of the thesis, tend to demonstrate the achievement of objectives

Full textThe work presented in this dissertation deals with modeling and formalizing models of Systems-on-Chip at the Transaction Level (TLM). These models complement traditional RTL models, allowing among others the development of the embedded software before RTL or the chip is available. Other activities making use of TLM, such as performance evaluation, require additional details in the models, notably time or behavior linked to time. We propose a study covering a novel technique that allows to enrich functional TL Models with additional information, expressed in plain SystemC. This technique keeps the added information separated from the original functional model, and guarantees functionality preservation. Our study is backed by an original formalization of SystemC, that does not require an explicit model of the scheduler. This formalization also allows local reasoning, at the level of the components of the mode!

Full textQuantitative relationships were studied between external traits and dendrometric characteristics of beech trees on the one hand, and the occurrence and geometric shape of red heartwood (RH) on the other hand: I. External traits (dead branches, branch scars, wounds, cracks, fork) and the RH shape were described three-dimensionally and in detail on 4 trees. Thus, hypotheses were deduced about RH initiation based on branch scar/knot dimensions, and about stages of development of the RH shape. II. A type logistic regression model was developed which made it possible to quantify the effect of individual branch scars on the probability of RH occurrence. It also included an effect at the dendrometric level. 27 out of 31 trees were correctly classified. III. The overall RH shape (mean RH radius along the stem axis) was modelled using parameters for the RH width, length and height in the tree. The parameters could be estimated from branch scars and dendrometric variables. The model was parameterised using 16 trees. It was applied to an independent sample which consisted of the 4 trees of analysis I. IV. Local deviations from the overall RH shape were analysed below and above knots. This was done on 58 boards taken from the 16 trees of analysis III. Deviations were limited to the knot zone and to the upper RH end. As perspectives, the importance of validation of the RH models is stressed. It could also be considered to link the RH models to models of tree growth or roundwood processing

Full textThe rapid pace of development in microelectronics enables the semiconductor industry to constantly surpass itself and to offer ever more innovative and complex products and technologies. The most modern areas of development, such as 5G, the Internet of Things (IoT) and automotive, rely on complex, high¬-performance, low-¬power designs. Unfortunately, this increased complexity often leads to higher power consumption and more challenging designs. In order to solve these problems and differentiate themselves in the market, System¬-on-Chip (SoC) manufacturers and engineers are putting tremendous effort into researching new development strategies. Numerous studies have shown that one of the key steps to take is to revisit the early stages of the design flow and, in particular, to integrate simulation-based modeling and verification at a higher level of abstraction. The early stages of product development are critical to avoiding costs, delays, and other unexpected problems. As a result, Hardware/Software (HW/SW) architectural exploration has become a key component of SoC modeling. In this thesis, we address this gap and present a framework for mixed performance and power estimation/management of SoCs using high¬-level SystemC/TLM2.0 functional models. Our methodology allows us to dynamically extract performance and power, while considering functional model activity, power management and reduction strategies, and memory system consumption. In this way, we can observe the impact of power management on performance and optimize the trade¬off between the two at the very beginning of the design flow. We address this shortcoming and present our first dynamic approach for mixed power/performance estimation applied to an NXP Intellectual Property (IP) interconnection subsystem used in i.MX8 SoC series. This modeling methodology uses the PwClkARCH library, which follows UPF semantics and enables power estimation and management. Its key point is that it maintains a strong separation between the functional code and the power intent description. There is no intrusive power¬-oriented code in the functional model, which simplifies architectural exploration, allows joint and separate reuse of behavioral and power models, and leads to more complete code and easier performance estimation

Full textThe high-level cyclist main goal is to win and optimize his performance. A question often raised by the athlete and his coaching is the link between asymmetry, performance and health. In this context, we analyze the kinematic and muscular adaptation of the dominant leg of professional cyclist during the incremental test to exhaustion of the FFC. The results showed that the increase of power output modifies the muscular coordination before impacting joint kinematics. Then, wepropose a new methodology to study the kinematic evolution of the spatio-temporel asymmetry during this test. The results showed that asymmetry level is greater outside the sagittal plane, which can creat a risk of injuries mainly for the knee. Finally, we examine the influence of fatigue on the level of muscular asymmetry though musculosketal modeling on a population of high level cyclists. Results showed that muscle asymmetry is different between electromyographic and musculoskeletal analysis. Moreover, the dominant side has a higher level of muscle strength and intersegmental reactions. From a general point of view, the methodologies used in this manuscipt have a direct application for cycling. However, they can be reused in other activities, from a performance and injury prevention viewpoint

Full textThe work presented in this thesis deals with modeling, specification and testing of models of Systems-on-a-Chip (SoCs) at the transaction abstraction level and higher. SoCs are heterogeneous: they comprise bothhardware components and processors to execute embedded software, which closely interacts with hardware.SystemC-based Transaction Level Modeling (TLM) has been very successful in providing high-level executablecomponent-based models for SoCs, also called virtual prototypes (VPs). These models can be used early in thedesign flow for the development of the software and the validation of the actual hardware. For SystemC/TLMvirtual prototypes, Assertion-Based Verification (ABV) allows property checking early in the design cycle,helping to find bugs early in the model and to save time and effort that are needed for their fixing. TL modelscan be over-constrained, which means that they do not represent all the behaviors of the hardware, and thus,do not allow detection of some malfunctions of the prototype. Our contributions consist of two orthogonal andcomplementary parts: On the one hand, we identify sources of over-constraints in TL models appearing due tothe order of interactions between components, and propose a notion of loose-ordering which allows to removethese over-constraints. On the other hand, we propose a generalized stubbing mechanism which allows the veryearly simulation with SystemC/TLM virtual prototypes.We propose a set of patterns to capture loose-ordering properties, and define a direct translation of thesepatterns into SystemC monitors. Our generalized stubbing mechanism enables the early simulation with Sys-temC/TLM virtual prototypes, in which some components are not entirely determined on the values of theexchanged data, the order of the interactions and/or the timing. Those components have very abstract speci-fications only, in the form of constraints between inputs and outputs. We show that essential synchronizationproblems between components can be captured using our simulation with stubs. The mechanism is generic;we focus only on key concepts, principles and rules which make the stubbing mechanism implementable andapplicable for real, industrial case studies. Any specification language satisfying our requirements (e.g., loose-orderings) can be used to specify the components, i.e., it can be plugged in the stubbing framework. We providea proof of concept to demonstrate the interest of using the simulation with stubs for very early detection andlocalization of synchronization bugs of the design
