SystemC cosimulation and emulation of multiprocessor SoC designs

Abstract: SystemC is an open source C/C++ simulation environment that provides several class packages for specifying hardware blocks and communication channels. The design environment specifies software algorithmically as a set of functions embedded in abstract modules that communicate with one another and with hardware components via abstract communication channels. It enables transparent integration of instruction-set simulators and prototyping boards. The authors describe a simulation environment that targets heterogeneous multiprocessor systems. They are currently working to extend their methodology to more complex on-chip architectures.

Implicit test generation for behavioral VHDL models

Abstract: This paper proposes a behavioral-level test pattern generation algorithm for behavioral VHDL descriptions. The proposed approach is based on the comparison between the implicit description of the fault-free behavior and the faulty behavior, obtained through a new behavioral fault model. The paper will experimentally show that the test patterns generated at the behavioral level provide a very high stuck-at fault coverage when applied to different gate-level implementations of the given VHDL behavioral specification. Gate-level ATPGs applied on these same circuits obtain lower fault coverage, in particular when considering circuits with hard to detect faults.

A SystemC-based framework for modeling and simulation of networked embedded systems

Abstract: Next-generation networked embedded systems pose new challenges in the design and simulation domains. System design choices may affect the network behavior and network design choices may impact on the system design. For this reason, it is important -at the early stages of the design flow- to model and simulate not only the system under design, but also the heterogeneous networked environment in which it operates. For this purpose, we have exploited a modeling language traditionally used for System design -SystemC- to build a system/network simulator named SystemC Network Simulation Library (SCNSL). This library allows to model network scenarios in which different kinds of nodes, or nodes described at different abstraction levels, interact together. The use of SystemC as unique tool has the advantage that HW, SW, and network can be jointly designed, validated and refined. As a case study, the proposed tool has been used to simulate a sensor network application and it has been compared with NS-2, a well-known network simulator; SCNSL shows nearly two-order-magnitude speed up with TLM modeling and about the same performance as NS-2 with a mixed TLM/RTL scenario. The simulator is partially available to the community at http://sourceforge.net/projects/scnsl/.

HIFsuite: tools for HDL code conversion and manipulation

Abstract: HIFSuite ia a set of tools and application programming interfaces (APIs) that provide support for modeling and verification of HW/SW systems. The core of HIFSuite is the HDL Intermediate Format (HIF) language upon which a set of front-end and back-end tools have been developed to allow the conversion of HDL code into HIF code and vice versa. HIFSuite allows designers to manipulate and integrate heterogeneous components implemented by using different hardware description languages (HDLs). Moreover, HIFSuite includes tools, which rely on HIF APIs, for manipulating HIF descriptions in order to support code abstraction/refinement and postrefinement verification.

Native ISS-SystemC integration for the co-simulation of multi-processor SoC

Abstract: In a system-level design flow, the transition from a high-level description entry implies the refinement from an untimed, unpartitioned description to a real architecture where applications are executed on a programmable device and interact with ad-hoc hardware components. Simulation of such architectures requires the capability of efficient co-simulation of a model of hardware with a model of the processor. This paper presents two co-simulation methodologies, based on SystemC as hardware modeling language and on an instruction set simulator (ISS) as a model of the processor. The first one works at the SystemC kernel level and exploits potentialities of the GNU suite, whereas the second uses features offered by the operating system running on the ISS. The two methodologies improve co-simulation performance with respect to state-of the art methods, and provide different trade-offs between the simplicity of the programming model, the modeling power, and co-simulation performance.

An Analysis and Survey of the Development of Mutation Testing

Abstract: Mutation Testing is a fault-based software testing technique that has been widely studied for over three decades The literature on Mutation Testing has contributed a set of approaches, tools, developments, and empirical results This paper provides a comprehensive analysis and survey of Mutation Testing The paper also presents the results of several development trend analyses These analyses provide evidence that Mutation Testing techniques and tools are reaching a state of maturity and applicability, while the topic of Mutation Testing itself is the subject of increasing interest

Model Driven Engineering

Abstract: The Object Management Group's (OMG) Model Driven Architecture (MDA) strategy envisages a world where models play a more direct role in software production, being amenable to manipulation and transformation by machine. Model Driven Engineering (MDE) is wider in scope than MDA. MDE combines process and analysis with architecture. This article sets out a framework for model driven engineering, which can be used as a point of reference for activity in this area. It proposes an organisation of the modelling 'space' and how to locate models in that space. It discusses different kinds of mappings between models. It explains why process and architecture are tightly connected. It discusses the importance and nature of tools. It identifies the need for defining families of languages and transformations, and for developing techniques for generating/configuring tools from such definitions. It concludes with a call to align metamodelling with formal language engineering techniques.

Ministry of Education and Science of the Russian Federation

Abstract: Summary) The abstract should follow the structure of the article (relevance, degree of exploration of the problem, the goal, the main results, conclusion) and characterize the theoretical and practical significance of the study results. The abstract should not contain wording echoing the title, cumbersome grammatical structures and abbreviations. The text should be written in scientific style. The volume of abstracts (summaries) depends on the content of the article, but should not be less than 250 words. All abbreviations must be disclosed in the summary (in spite of the fact that they will be disclosed in the main text of the article), references to the numbers of publications from reference list should not be made. The sentences of the abstract should constitute an integral text, which can be made by use of the words “consequently”, “for example”, “as a result”. Avoid the use of unnecessary introductory phrases (eg, “the author of the article considers...”, “The article presents...” and so on.)
