DEVICE AND METHOD FOR DISPLAY OF CIRCUIT DIAGRAM

PROBLEM TO BE SOLVED: To provide a circuit diagram display device and method, for allowing a user to efficiently and accurately confirm a circuit logic. SOLUTION: The circuit diagram display device includes: a memory for storing information of a circuit; a display unit for displaying the circuit; an input unit which receives input for designating a fixed value to be input to the circuit; and a fixed value propagation unit which, when the fixed value designated by the input unit is input to the circuit, extracts part of the circuit which is blocked by propagation of the fixed value. The display unit hides the part to be blocked of the circuit which is extracted by the fixed value propagation unit. COPYRIGHT: (C)2011,JPO&INPIT
