EXAMPLES Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 11 denotes connection point coordinates of each device, which are generated by upstream CAD, and start coordinates of a line of each section of a cable connecting these devices,
It is attribute data including end coordinates, wire numbers, distances, and the like. 12
Processes the start coordinates, the end coordinates, and the wire number of the line of each section of the cable in the attribute data 11 to create a connection recognition table describing the connection of each line regarding the wiring route included in one connection recognition. Reference numeral 13 is a table creating process, and 13 is a connection recognition table created in the table creating process 12. Reference numeral 14 is a route extraction process for extracting the shortest wiring route between designated devices by referring to the connection recognition table 13, and reference numeral 15 is a wiring route diagram based on the extracted wiring route.

FIG. 2 is a wiring conceptual diagram showing the attribute data 11. In the drawing, 1 is a device, 2 is a line, 3 is a distance, and corresponds to the same reference numerals in FIG.
Reference numeral 4 is a line number of each of the lines 2 numbered so as not to overlap, and 5 is coordinates of end points of the lines 2.

Next, the operation will be described. First, in the table creation processing 12, the coordinates and the wire numbers of the end points of the line 2 of each section of the cable in the attribute data 11 are processed, and the connection of each line related to the wiring route included in one connection recognition is calculated as a connection recognition table. Described as 13. here,

1) The coordinates 5 of the end point whose start coordinates or end coordinates do not match the start coordinates or end coordinates of the other line 2 are searched (step ST2) and set as the start coordinates (step ST3). At this time, the information of the line 2 having the start coordinates is written in the format of FIG. 3 (step ST5). Next, the coordinate 5 of the other end point is set as the next search coordinate (step ST
6) Read the attribute of line 2 from attribute data 11 until matching line 2 is detected (step ST9) (step ST9).
7). If they match, the passage flag is set to 1 (step S
T4), the above processing is repeated. If there is no coincident line even if all cases are searched (step ST11), the passage flag is set to -1 (step ST12), and the coordinate 5 of the other end point of the same line 2 is returned as the next search coordinate. The line for which the passage flag is set to -1 in the search is removed from the subsequent searches (step ST8). The above processing is repeated until the start coordinates are returned (step ST10). By this series of processes, the connection recognition table 13 for the line 2 in the entire section shown in FIG. 3 is completed.

Next, referring to the connection recognition table 13, the coordinates (X ₁ , Y ₁ ) → (X ₂ ,
Y ₂ ), (X ₂ , Y ₂ ) → (X ₃ , Y ₃ ), (X ₃ , Y ₃
) → (X ₂ , Y ₂ ), (X ₂ , Y ₂ ) → (X ₄ , Y
₄ ), (X ₄ , Y ₄ ) → (X ₅ , Y ₅ ), and as shown in FIG. 5A, S4 → S3 → S3 → S2 →
The wiring route of S1 is extracted, and the folded portion in which the wire number 4 is the same and the passage flag has the opposite sign is erased. As a result, the shortest wiring route S4 for connecting the device A and the device B
→ S2 → S1 is extracted. The same applies to the other wiring routes. When the device B and the device C are designated, the coordinates from the respective connection point coordinates (X ₅ , Y ₅ ) to (X ₃ , Y ₃ ) are arranged in order. S1 → S2 shown in FIG. 5 (b)
→ S4 → S4 → S1 which erased the folded part in S3
→ S2 → S3 wiring route is extracted.

Example 2. In the first embodiment described above, the wiring type of the line 2 in each section of the cable is not limited, but as shown in FIG. 6, the wiring type of each of the lines 2 in each section of the cable is included in the attribute data 11 as shown in FIG. By including the data indicating, the total cable length for each wiring type can be picked up.
