<p>PURPOSE:To improve the electric circuit design work efficiency, etc., by displaying a connecting relation between electric circuits of different blocks in a more easily understandable form. CONSTITUTION:Circuit diagram data 10 is data of a circuit diagram in which elements, etc., mutually connected are combined and subjected to blocking, and expressed hierarchically. Window size data 12 is data of size of a window for displaying the circuit diagram. A display magnification input part 14 inputs magnification of the circuit diagram displayed on the window. A ratio calculating part 20 calculates a ratio R of symbol size SS of a block displayed on the window to window size SW. A block display deciding part 22 determines whether a display of the pertinent block is set as a symbol display or a schematic display in accordance with the magnitude of the ratio R. The schematic display to the extent of the lower layer is displayed simultaneously under the condition of resolution of a CRT, etc.</p> |
