Reconciling conflicting design-automation standards

Article Abstract:

Several computer-aided design and engineering (CAD/CAE) standards were developed in the race to provide design-automation products in the mid-1980s, but the standards differ in many important ways and do not communicate with one another very easily. Representatives for the different standards have recently begun to work together to bring the various standards into harmony; these include the Electronic Design Interchange Format (EDIF), the Initial Graphics Exchange Specification (IGES), standards developed by the Institute for Interconnecting and Packaging Electronic Circuits (IPC) and the Very High-Speed IC Hardware Description Language (VHDL). The areas and levels addressed by each of the four are described. ANSI organized formal meetings after industry leaders requested development of a single consistent set of American National Standards aligned with international standards. Roadblocks to the development of the CAD/CAE 'superstandard' are discussed.

Software R&D: from an art to a science

Article Abstract:

Software engineering is slowly becoming the subject of formal rules and structures for a methodical engineering discipline similar to electrical or mechanical engineering. As development techniques become more structured and disciplined, more attention is being given to the mathematical basis of software engineering. Object-oriented programming is the hottest technology at present in software engineering. Reusable components are often widely used in chip design, however many software engineers are not in favor of using other people's reusable software development components. Most software development follows the waterfall model: requirements, specification, design, implementation, testing and maintenance. The science of software development has not yet matured enough to blend with commercial software engineering.

Transportation

Article Abstract:

IBM Corp will supply computers and controller workstations for the $16 billion National Airspace System. The traffic-alert collision avoidance system will be required on all commercial aircraft carrying more than 30 passengers by mid-1992. Three US railroads are testing an advanced train-control system (ATCS) with a standard hardware interface and communication protocol will use a data link to relay a train's exact location from the locomotive to a control center.
