Method of automatic circuit translation

Abstract

In a case where an electronic circuit having the same function is to be realized by a different device, it is indispensable to prepare circuit diagrams conforming to devices and to utilize them for the job of circuit simulation or chip layout. When the circuit diagrams are to be automatically translated for the above purpose, translation rules become different depending upon the connective relations of an element to be translated, with other elements in the circuit or upon a function performed by the element. The present invention puts the rules into knowledge from the viewpoint of knowledge engineering and utilizes it thereby to realize the intended purpose. It is characterized in that, when a circuit constructed of a first type of elements is to be translated into a circuit constructed of second type of elements different from the first type of elements, appropriate ones among translation rules are automatically selected for the respective first or second type of elements on the basis of determined results based on knowledge groups of connective relations with other elements of the same circuit and are applied to the first or second type of elements.
