Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a wiring method on a wiring board.

[Prior art]

Ta. Therefore, if the wires are wired in parallel over a certain length, the wires will affect each other electrically, making it difficult for the electrical circuit to operate correctly, which has the disadvantage that the wires must be manually corrected frequently. Ta.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a wiring system in which an arbitrary wiring grid can be placed on a wired line.

[Structure of the invention]

The wiring system of the present invention includes a wiring grid point data storage means for storing wiring grid point data to be connected, a wiring prohibited grid number storage means for storing the number of wiring prohibited grids for the line length of a line segment, and each wiring grid point. While sequentially retrieving the wiring grid point data to be connected from the grid point attribute storage means that stores the attribute of whether or not is a wiring prohibited grid point and the wiring grid point data storage means, and referring to the attributes of the grid point attribute storage means. The wiring means for wiring and the line resulting from the wiring by the wiring means are divided into line segments, the number of wiring prohibited grids for each line segment is obtained from the wiring prohibited grid number storage means, the wiring prohibited grid points for the line segment are generated, and the grid is divided into line segments. It has a wiring prohibition grid point detection means that sets the attribute of the wiring grid point in the point attribute storage means as a wiring prohibition grid point, and a wiring data output means that outputs the wiring result.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of a wiring processing method according to an embodiment of the present invention.

The wiring grid point data storage means 1 is composed of a memory element or a magnetic file, and stores wiring grid points (starting points, starting points, etc.) to be connected.
The position data of the end point) is shown in Table 1. The data is composed of child or magnetic files, and the number of wiring prohibited grids for each line length range of the line segment is stored in table format as shown in Table 2. There is.

B - Table-2 Grid point attribute storage means B stores the attributes of all the grid points on the wiring board, that is, whether they are a wiring grid that can be routed (vacant) or a wiring grid that cannot be routed (wiring prohibited or already wired). The table-format wiring means 4, in which the information of @0" or "l" shown in Table 8, retrieves from the wiring grid point data storage means 1 the X coordinates,
The coordinates are sequentially taken out from seek number 1, and while referring to Table 8 of the grid point attribute storage means 8, a grid point that can be wired is searched for and wired. Once the wiring is completed, as wiring data,
If the wiring cannot be completed, it is sent to the wiring data output means 6 as unwired data. Further, when the wiring is completed, the wiring result is sent to the wiring prohibition grid point generation/means 5.

The wiring prohibition grid point generation means 5 divides the line resulting from the wiring into line segments, and for each line segment, refers to Table 2 of the wiring prohibition grid number storage means 2 to determine the wiring prohibition grid point for the line length range. The number is found, a wiring prohibition grid point for the line segment is generated, and the attribute of the wiring grid point in the grid point attribute storage means 80 Table-8 is set to 11''.

The above wiring means 4 and wiring prohibited grid point generator are then carried out. In this way, data on the lattice points that can be wired and data on lattice points that cannot be wired are outputted from the wiring data output means 6.

Next, an example of wiring according to the wiring method of this embodiment will be explained in comparison with an example of wiring according to the conventional method.

Figure 2 shows an example of wiring using the conventional method, with wiring grid point data 1
(start point F5 end point Tt) and wiring grid point data j (start point Fj
, Tj) is an example of wiring in which empty lattice points are assigned between the lines. Is the wiring of wiring grid point data 1 (start point F1. end point Fj) a line segment in the X direction? (line length ap, p is the grid interval) and line segment 8 in the Y direction
(line length 8p). Here, these line lengths 6p are listed in Table 2 of the wiring prohibited lattice point generation means tommo→2.

Assuming that 2°1 is stored as the number of wiring prohibited grids for each 8p, the wiring prohibited grid point generating means 5
The grid point marked with an X is generated as a wiring-prohibited grid point, and data of "1'" indicating that it is a wiring-prohibited grid point is entered in the attribute column of the wiring grid point in the grid point attribute storage means 80 Table-8. I'm good at writing.

As a result, the next wiring grid point data j (starting point Fj).

The wiring at the end point Fj) is composed of line segments 9.10 and 11.19, avoiding these wiring prohibited grid points.

〔Effect of the invention〕

As explained above, the present invention can prevent the wired heddles from electrically influencing each other by providing an appropriate wiring grid before and after the wired wires.
