This thesis discusses an automatic drawing system for electronic circuit diagrams. An input method is based on input description language which is real input data file of SPICE2: a simulation package for electronic circuits. And automatic drawing is executed through a Tektronix 4010-1 graphic display terminal. In this thesis, an input method, placement method of each electronic components, and interconnection problem are proposed and designed. And to present a more visible circuit diagram, labeling and scaling problems are considered. The system is implemented on a VAX 11/780 running under UNIX operating system and mainly programmed in FORTRAN77.
