The need for care in designing input graphics programs (preprocessors) for Computer-Aided Circuit Design packages is discussed. A graphics preprocessor and associated algorithm is described whereby a picture presentation by the designer is converted to analysis information by the input graphics program of SPLAP — Sunderland Polytechnic Linear Analysis Program.
