    The demand for automated design tools for the design of thick-film and hybrid circuits has grown dramatically over the last few years. The article describes the requirements for hybrid CAD and the main features of the Visula hybrid design system, and also includes a description of hybrid circuits and how they are manufactured.<> View full abstract»

    Design optimisation is a primary objective in computer-aided engineering. In the paper the optimisation of a linear variable differential transformer is used as an example. The study shows two typical features of computer-aided engineering: first that analysis techniques can be used to give measurements of system parameters that could not be achieved in a practical experiment; secondly that the de...

    Describes the concepts and the status of the CATHEDRAL-II silicon compiler for digital signal processing systems. It is shown that efficient layout synthesis is possible, starting from a very high-level behavioural description of a system, owing to the careful definition of a target architectural design style and an application domain. An overview is presented of the different synthesis tools whic... View full abstract»

    Describes concept and techniques for transforming data, structured to correspond to orthographic views of engineering components, into formal three-dimensional solid models: the theoretical basis for the process is constructive solid geometry. Various algorithms have been developed for executing the transformation for prismatic and so-called orthoprismatic objects with extension to the concept of ... View full abstract»

  • The implications of tolerancing for computer-aided mechanical design

    Publication Year: 1988, Page(s):79 - 85

    Discusses the implications for current CAD systems of conveying tolerance information through examination of the re-use of geometric data. The concepts underlying this data re-use, notably data integrity and information flow, are also considered with respect to the overall design/manufacturing process. Tolerance application and analysis is considered within this context, and recent work carried ou... View full abstract»
