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, a circuit diagram design program and a circuit diagram design method suitable for designing a circuit diagram related with a semiconductor integrated circuit including a multi-element circuit configured by continuously connecting a circuit element such as an MOS transistor through a shared section. PSOLUTION: A circuit diagram design device 100 includes: a circuit symbol selection part 12 for selecting a circuit symbol from a layout-processed circuit diagram or selection screen; a circuit diagram display control part 16 for performing the display control of a circuit diagram based on display information; a parameter setting part 18 for setting a parameter for generating a multi-element circuit for a circuit symbol whose parameter setting is possible; a connection relation information generation part 20 for generating the connection relation information of the multi-element circuit based on a preliminarily set rule and the parameter set for the circuit symbol; and a circuit display information generation part 22 for generating the display information of the circuit symbol of the multi-element circuit based on the preliminarily set rule of a display method.
