Abstract: As a step toward the automatic understanding of electronic circuits, we present a logic grammar as a new method of knowledge representation for structure and function of electronic circuits. In this work, we view a circuit as a sentence and its elements as words. Circuit structures are then defined by grammar rules. A set of grammar rules, when converted into Prolog clauses, forms a logic program winch performs top-down parsing. A circuit is designed to perform specific functions to achieve its goal. We see these functions as the meaning of the circuit. This new circuit grammar defines not only the syntactic structures of circuits, but also their relations to the functions. When a given circuit is parsed as a grammatical sentence, not only its syntactic structure but also its functions are derived. A simple English interface generates explanations on the circuit structure and functions.
