title Automated knowledge Acquisition for a Computer Hardware Synthesis System

summary The MICON Synthesizer Version 1 (M1) is a rule-based system which produces a complete small computer design from a set of abstract specifications. The ability of M1 to produce designs depends on the encoding of large amounts of domain knowledge. An automated knowledge acquisition tool, CGEN, works symbiotically with M1 by gathering the knowledge required by M1. CGEN acquires knowledge about how to build and when to use various computer structures. This paper overviews the operation of CGEN by providing an example of the types of knowledge acquired and the mechanisms employed. A novel knowledge-intensive generalization scheme is presented. Generalization is a pragmatic necessity for knowledge acquisition in this domain. A series of experiments to test CGEN's capabilities are explained. A description of the architecture and knowledge-base of M1 is also provided

title Capturing Designer Expertise : The CGEN System

summary Knowledge-based systems are becoming pervasive in the computer-aided design area. For these systems to achieve satisfactory levels of performance large amounts of knowledge are necessary. However, the acquisition of knowledge is a difficult and tedious task. Automated knowledge-acquisition tools (AKAT) provide capabilities for quickly building and maintaining knowledge-bases. This paper describes the CGEN AKAT, which allows hardware designers, unfamiliar with artificial intelligence programming techniques, to deposit their expertise into a synthesis tool's knowledge-base. A set of experiments which tested CGEN's capabilities are presented. The experiments show that with CGEN hardware designers can produce high quality knowledge-bases

title The MICON System for Computer Design

summary The MICON system is an integrated collection of programs which automatically synthesizes small computer systems from high level specifications. The system address multiple levels of design, from logical through physical, providing a rapid prototyping capability. Two programs form MICON's nucleus: a knowledge-based synthesis tool called M1; and, an automated knowledge acquisition tool named CGEN which is used to teach M1 how to design. Other tools in the MICON system are an integrated database and associated data management tools. The system is fully functional, having been used to generate working designs. This paper describes the architecture and operation of the MICON system
