SOFT IP CUSTOMIZATION MODELS BASED ON HIGH-LEVEL ABSTRACTIONS

System-on-Chip (SoC) design raises an abstraction level in hardware (HW) design beyond a domain language specification. This requires the introduction and adoption of high-level analysis and specification methods that provide reusability, layericity, orthogonality, heterogeneity and customizability for HW design. HW design has many levels of abstraction. The transition between these levels can be described using a concept of design process. As there may be many representation and design methods for a designer to choose from, while implementing a certain design process, we describe several Design Flow Models aimed at implementing customization in soft IP-based HW design. These models apply several concepts taken from software engineering (object-oriented and pattern-based design, metaprogramming, parsing, and markup languages) to HW design.

The design process of expert systems development: some concerns

Abstract: A discussion is presented of why some expert systems that organizations have developed are not successful. The concept of design process plays a very significant role at the outset of the expert system development process. This concept has not been the subject of much debate and attention in expert systems development. From the author's point of view, one of the main issues is how the designer (knowledge engineer) thinks about the design process. In general, the designer's process is influenced by the knowledge engineer's conception. This paper endeavors to disclose some of the main factors related to the knowledge engineer's conception of the design process and an attempt is made to put forward a conceptual model of the expert system design process. This conceptual model is an initial step towards a successful implementation of expert system projects.
