Khalid E. Means of building of applied expert system based on three-component model

The expert system, functioning in area of generation of code in some programming language proceeding from the visual description of the project in designer’s language is developed in the dissertation. To construct the expert system we have chosen three-component model of the performance of knowledge’s consisting of a grammar, calculus of predicates and bases of meta knowledge’s, transforming knowledge’s from structured form in khornov’s dyzonkte. The technique of the expert system’s adaptation to generations of code VHDL proceeding from the visual description of the digital device in developer’s language and the principle of the construction of knowledgebase’s for automatic generation of code VHDL are shown. Algorithms of generation of code VHDL for digital devices aree developed. Behavior of algorithms is described by combinational logic in the form of the table, bolyvo’s function, and also consequent logic in form of final automatic device
