Schematic design equipment, schematic design program and a circuit diagram design method

摘要

PPROBLEM TO BE SOLVED: To provide a circuit diagram-design device which is suitable for designing a circuit diagram relating to a semiconductor integrated circuit including a multi-element circuit in which circuit elements such as MOS transistors are connected in series via common parts, and to provide a circuit diagram-design program and a circuit diagram-design method. PSOLUTION: The circuit diagram-design device 100 includes: a circuit symbol-selecting part 12 which selects circuit symbols from a symbol circuit diagram or a selection screen; a circuit diagram-display control part 18 which controls the display of a circuit diagram; a parameter-setting part 20 which sets parameters for generating a multi-element circuit to circuit symbols to which the parameters can be set; a parameter-determining part 22 which determines whether the set parameters are correct or incorrect; a parameter-correcting part 24 which corrects the incorrect contents of parameters to the correct parameters if any incorrect contents exist; and a connection relation information-generating part 26 which generates connection relation information relating to the multi-element circuit on the basis of a preliminarily set rule and the parameters set to the circuit symbols.
