Automatic Input and Interactive Editing Systems of Logic Circuit Diagrams

This paper discusses automatic input and interactive editing systems of logic circuit diagrams. Automatic input is based on pattern recognition, and interactive editing is executed through a graphic display. The system is implemented on a FACOM M-180 II and a PANAFACOM U-400. System overview, hardware configuration, pattern recognition algorithms, editing system, data-base, as well as current results are described.
