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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
