The usefulness of such chips are limited in a world dominated by information that is not represented by 0's and 1's. Overcoming these limitations has led to mixed-signal, and mixed-domain technologies. We focus on design methodologies and tools to aid the design of complex microelectromechanical systems (MEMS) having large numbers of mixed-domain components. We propose a hierarchically structured design approach that is compatible with standard IC design involving a schematic approach to MEMS design, a layout synthesis strategy for cell-level design automation, and a feature-recognition based device extractor for layout verification. We present emerging results on our design methodology and tools.","PeriodicalId":185325,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI'98 System Level Design (Cat.

Design and optimization of networked wireless information systems 网络无线信息系统的设计与优化
Mani Srivastava, Ee
{"title":"Design and optimization of networked wireless information systems","authors":"Mani Srivastava, Ee","doi":"10.1109/IWV.1998.667119","DOIUrl":"https://doi.org/10.1109/IWV.1998.667119","url":null,"abstract":"As entire systems are being integrated on a single chip, the chip designers are in effect becoming the system designers. However, it is an open question whether the board-level system architecture design and optimization methodologies are also well-suited for such system-chips. Our experience with the networked wireless multimedia nodes and devices being designed under UCLA's MERLIN project shows that the system-chip design problem is not just one of complexity and scalability arising from a large number of transistors. Instead, the primary problem and opportunity is in managing the diversity in a system, and exploiting it to optimize the system architecture. Indeed, the ability to do design tradeoffs and optimizations across diverse system layers and functions being integrated on a die is crucial. Facilitating such system level optimization ought to be the focus of design automation tools, and not the mere integration of cores encapsulating intellectual property. Supporting \"tall and thin\" chip designers is no longer adequate. The tools for system-chip design have to support \"tall and fat\" designers who, for example, need to optimize across the radio, protocol, DSP, and microcontroller functions in a wireless system-chip.","PeriodicalId":185325,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI'98 System Level Design (Cat.

Commercial systems face increasing complexity and performance requirements, while achieving decreasing times to market and maximizing profits despite shrinking product life-cycles. Defense systems face similar issues, but must also support life cycles which span years or decades, thus requiring redesign, support or prevention of parts obsolescence challenges. For cost-effective development of systems in this context, design teams need to exploit the best commercial and defense design practices and adapt them as needed to also support concurrent engineering considerations. This paper explores requirements for the emerging system level design language and the methodological needs for it to support multi-disciplinary design, including hardware software co-design, mechanical and packaging support, concurrent engineering, test, and related issues.","PeriodicalId":185325,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI'98 System Level Design (Cat.

Increasing miniaturization brought on by advances in areas such as VLSI design means that we will soon be able to instrument our environments in order to realize the dream of ubiquitous computing. The promise of ubiquitous computing, however, is that the increased pervasiveness of computation will lead to less intrusive and more valuable services to the end user. For this dream to be realized we need to accompany hardware advances with advances in software technology. In this paper, the author discusses some software challenges for ubiquitous computing.","PeriodicalId":185325,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI'98 System Level Design (Cat.

System level description formalisms should combine concepts expressive enough to model the essentials of a system on the right level of abstraction. This paper reports experiences in developing a specification and design method SHE (Software/Hardware Engineering) which is based on a formal language POOSL (Parallel Object-Oriented Specification Language). The method offers a path from an informal specification to a unified formal model that enables evaluation of system properties.

On the custom hardware side, several system level memory management related methodologies are being proposed which promise very large savings on power and also on area while still meeting the real-time constraints. Unfortunately, on the software side these methodologies are not applicable as such. In order to alleviate this situation for systems-on-a-chip with a heterogeneous mix of processors, novel methodology and architecture approaches are required. In this research summary paper, the currently available solutions are reviewed and some major problems to be solved in the future are identified.","PeriodicalId":185325,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI'98 System Level Design (Cat.
