An approach for classification of integrated circuits by a knowledge conserving library concept

A simulation based analysis of analog and mixed analog/digital circuits on printed circuit board level requires a lot of information about the involved components. Entering solely the data sheet information into a component library normally disregards structural knowledge which is well-known by the circuit designer. Therefore, the expert knowledge necessary for an optimum use of analysis tools is no more available. This paper presents an approach to overcome this problem. A concept to represent efficiently expert knowledge and classification information is introduced and a classification of circuits which conserves the structural information is presented
