    The paper describes the dilemma of the merchant semiconductor company, where increased complexity of semiconductor devices results in increased development costs, while, in many cases, increased complexity means increased specialisation and therefore reduced volumes. The solution proposed is to transfer design to the equipment companies. This solution is only practical if the expertise of the chip... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1149 KB)

    The design of a gate array chip and process suitable for carrying out integrated circuit design exercises at an undergraduate level is described. The array uses simplicity in both processes and design in order to make these exercises economically feasible. The educational value in the exercise is in introducing the students to process design rules and their interpretation. Also it will teach, in a... View full abstract»

  • Proprietary semicustom regenerator IC for 140 Mbit/s optical transmission systems

    Publication Year: 1985, Page(s):62 - 67
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (672 KB)

    Uncommitted logic arrays have been available to system designers for several years, but have hitherto mainly found application in digital signal processing. In the paper a proprietary communication IC application is described using an ECL array containing a mixture of analogue and digital circuitry. The array regenerates the data signals of a high-speed optical-fibre transmission system. View full abstract»

  • Design techniques for a 565/680 Mbit/s coder/decoder

    Publication Year: 1985, Page(s):68 - 72
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (724 KB)

    The circuit design, process and layout techniques used to implement a high-performance silicon integrated circuit for a 565 Mbit/s multiplex and optical-fibre transmission system will be described. The IC contains 6000 transistors and operates at speeds well in excess of those normally achieved using semicustom circuit techniques, while retaining the normal advantages of semicustom design methods.

  • VLSI: the design problem

    Publication Year: 1985, Page(s):86 - 90
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (601 KB)

    An historical review of how technological advances leading up to the VLSI technology have changed the computer industry is presented. Two major problems of designing, using VLSI, are then discussed, with a description of how these are being tackled by one computer manufacturer for designing with VLSI in future systems.

  • The Megacell concept: an approach to painless custom design

    Publication Year: 1985, Page(s):91 - 98
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1694 KB)

    Megacell is a complete design package for the creation of complex VLSI chips. It allows system engineers to develop their own custom integrated circuits. The challenge of Megacell was to create a design system that would exploit fully the low-power and high-speed performance of a UK developed 2 ¿m CMOS technology, while producing the silicon utilisation efficiency typical of full custom design. T... View full abstract»

  • Hierarchical specification and switch-level simulation of digital circuits

    Publication Year: 1985, Page(s):102 - 107
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (661 KB)

    A software system for structured schematic documentation and switch-level simulation of digital integrated circuits is presented. By means of an interactive command language, the user can specify the schematic diagrams which document the actual digital design directly onto a graphical screen. This documentation can be performed hierarchically, in a manner where selected subcircuits are represented... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1055 KB)

    Chip designs should be produced by building from a large selection of appropriate component designs. Each component should be modular, but the resulting design should permit consistency checking. STRICT attempts to embody these principles in a formal notation for the design of integrated circuits. View full abstract»

  • Pascal circuit compiler for UK5000

    Publication Year: 1985, Page(s):116 - 120
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (631 KB)

    A Pascal compiler is described which can parse a limited subset of Pascal, and generates a circuit description in a format which can then be input to the UK5000 gate array software. A set of Pascal utilities completes this package by allowing the Pascal circuit description to be compiled by a standard Pascal system. This complete package allows the development of systems containing single or multi... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1200 KB)

    The paper presents a review of current and proposed test methodologies for semicustom gate arrays. The necessity of high quality testing is emphasised by considering some of the hazards and penalties associated with poor testability. The usefulness and limitations of testability analysis programs are then considered. A built-in test is introduced as an attractive alternative to conventional approa... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (397 KB)

    The semiconductor industry has been responsible for initiating a new phase in the world's economic and industrial development. For more than two decades, average price (and cost) per function has decreased by 30%, industry growth has averaged nearly 20% per year. Each year more memory bits are sold than in all the previous years added together. In the 35 years since the birth of the transistor, th... View full abstract»
