【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a circuit diagram creation / display device, FIG. 2 is a flowchart showing an operation of displaying a lower layer circuit on a hierarchically created upper circuit diagram, and FIG. 3 is a circuit diagram showing a hierarchically designed upper circuit. 4 is a circuit diagram of the lower layer circuit to be displayed,
5 is a circuit diagram in which a lower layer circuit diagram can be displayed on the upper circuit diagram, and FIG. 6 is a circuit diagram in which the lower layer circuit diagram is displayed on the upper circuit diagram. In FIG. 1, 1 is circuit diagram creating means, 2 is lower layer circuit diagram data, 3 is upper layer circuit diagram data, 4 is area reading means, 5 is lower layer circuit diagram display means, 6 is lower layer circuit diagram area data, and 7 is lower layer. Reference numeral 8 is a circuit diagram search means, 8 is a hierarchy display circuit diagram creating means, 9 is hierarchy display circuit diagram data, 10 is a circuit diagram display means, and 11 is a CRT display device.

Next, the operation will be described with reference to FIGS. When the user uses the circuit diagram creating means 1 to create the lower layer circuit diagram 2 and the upper layer circuit diagram data 3 having it as the lower layer (S1 in FIG. 2), the created upper layer circuit diagram data 3 is the circuit diagram displaying means. It is displayed on the CRT display device 11 by 10 (S2 in FIG. 2). On the upper circuit diagram (FIG. 3) displayed on the CRT display device 11, the symbol (a in FIG. 3) for which the lower layer circuit diagram is to be displayed is designated using the lower layer circuit display designating means 5 (S3 in FIG. 2). . The lower layer circuit diagram of the designated symbol is searched from the lower layer circuit diagram data 2 using the lower layer circuit diagram retrieval means 7 (S4 in FIG. 2). The lower layer circuit diagram area data 6 is read by the area reading means 4 from the searched circuit layer area of the lower layer circuit diagram (FIG. 4) (S5 in FIG. 2). The hierarchical display circuit creating means 8 changes the size of the designated symbol on the upper circuit diagram data 3 to the same size as the lower layer circuit diagram area data 6 (FIG. 5), and changes it to the symbol (a in FIG. 5). Hierarchical display circuit diagram data 9 in which lower layer circuit diagram data 2 is arranged (FIG. 6)
