Abstract

PURPOSE:To save the labor of a designer for preparing jumper wiring work instruction information and to prevent wiring work instruction misses and the operation miss of a wiring worker by automatically determining a jumper wiring route and generating a jumper wiring diagram. CONSTITUTION:A jumper wiring block is extracted from pattern design information or design change information, which are already recorded from an input/ output device 11 to a data storage device 13 in advance, and the wiring route is determined on a substrate. The wiring route determined according to a wiring rule is outputted by the plotter and the jumper wiring diagram is prepared. When the route is not discovered, a wiring route not to cross parallel pins is permitted.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a jumper wiring diagram generation processing method, and in particular, to the creation of jumper wiring work instruction drawings for unwired sections in printed circuit board pattern design and to The present invention relates to a jumper wiring diagram generation processing method for creating a modification instruction drawing using jumper wires.

[Conventional technology]

The conventional printed circuit board jumper wiring diagram generation processing method is
The method used was to draw the jumper wiring route manually, or to generate only a section line representing a logical wiring section.

[Problem to be solved by the invention]

The conventional jumper wiring diagram generation processing method described above has the problem that manual creation of jumper wiring route diagrams requires a large amount of man-hours for the designer and is prone to drawing creation errors. The display has a problem in that it can lead to errors by wiring workers who work while looking at the information.

[Means to solve the problem]

The jumper wiring diagram generation processing method of the present invention clicks the jumper wiring diagram generation processing method for a printed circuit board to generate jumper wiring routes from logical section information of through holes on component bins or circuit patterns that require jumper wiring. The configuration includes a determining means for automatically determining and a generating means for generating a wiring diagram.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The jumper wiring diagram generation processing method of the present invention is realized by the input/output device 11, the arithmetic processing unit 12, the data storage device 13, and the jumper wiring diagram generation mechanism 14. The jumper wiring diagram generation mechanism 14 includes the wiring route determining means 15 and It includes a wiring diagram generating means 16.

FIG. 2 is a flowchart showing the operation of the jumper wiring diagram generation mechanism 14 of FIG.

FIG. 3 is a block diagram showing an example of a wiring route and an example of route priority. The priority indicates that the lower number side has priority.

Next, the operation of the present invention will be explained according to the flowchart shown in FIG. However, the buttons in Figure 1 and Figure 3 will be quoted as necessary.

A jumper wiring section is extracted from the pattern design information and design change information stored in advance in the data storage device 13 (FIG. 1) from the input/output device 11 (FIG. 1) (step 21).
~22). The wiring route on the board is determined from the retrieved section information (step 23).

Due to the nature of jumper wiring, the wiring route is determined using the following wiring rules. 1; Priority is lowered for pulling out from the pin in the direction of the component outline and in the direction in which the pins are lined up (31 in Figure 3).
32). 2: If the hole is equipped with a jumper, the pattern from the pin to hole 1 is also output (33 in Figure 3).
). 3: The above pattern is not used as a wiring route (34 in FIG. 3). 4; Do not use the wiring route over the component pins (35 in Figure 3).

5; It is not considered a wiring route based on the part outline, but if a route cannot be found, a wiring route that does not cross the pin arrangement is allowed ($3
36) in the figure. The wiring route determined according to the above rules is output on a plotter and a jumper wiring diagram is created (step 24).
).

〔Effect of the invention〕

As explained above, the present invention automatically determines jumper wiring routes and generates jumper wiring diagrams, thereby reducing the number of man-hours required for designers to create jumper wiring work instruction information and preventing mistakes in wiring work instructions. This has the effect of preventing work errors by workers.
