Input unit 1, second input unit 3, data storage unit 4, display data processing unit 5, graphic display unit 6, and termination determination unit 7
The design data display unit 2 includes: Moreover, what is shown in FIG. 2 is a diagram showing an example of displaying the execution results according to the first embodiment.

In FIG. 1, the first input section 1 includes a keyboard function, through which the line width to be highlighted and its display color are input, and the output is It is input to the input section 3. The second input section 3 includes component pins 104 and 11 connected on the printed wiring board.
It has a function to input the coordinate values of 0, 105, and 109 (see Figure 2), the wiring routes 201 and 202 (see Figure 2), and the line width of the wiring, for example, using a stylus pen and keyboard. It is composed of etc.

The data output from the second input section 3, including the data input from the first input section 1, is input to the data storage section 4 and stored therein. The display data processing section 5 reads out the data stored in the data storage section 4 and displays the line width designated for highlighting in the first input section 1,
The line width of the wiring input in the second input unit 3 is compared and verified, and if the two line widths are the same, the highlighting color input in the first input unit 1 is given as the display color, and , if different, a predetermined standard display color is given, and a line width for display display corresponding to the line width input in the second input section 3 is determined, and a predetermined display color is determined. Wiring information is output. This wiring information is input to the graphic display section 6, and the wiring state on the printed board is displayed on a predetermined display screen. Then, the completion determination unit 7 determines whether all the component pins to be wired have been wired, and if the wiring has not been completed, the second input unit 3 performs display processing again. .

Next, an example of displaying the execution results according to this embodiment will be explained with reference to FIG.

In the first input section 1 shown in FIG. 1, the value of the line width W1 to be highlighted and the highlighting color C1 are input, and in the second input section 3, the position of the connection pin,
It is assumed that the wiring route and line width W2 are input. Here, an example in which the line width W2 is equal to the highlighted line width W1 is shown by the component pins 105, 109 and the wiring route 201 in FIG. and wiring route 20
2. If this line width W2 is different from the line width W1 to be highlighted, the line width W1 to be highlighted and the line width W2 of the wiring are compared and verified in the display data processing section 5 to determine the corresponding display color. Here, the wiring indicated by the wiring route 202 has a line width W
1, the display color C0 becomes the standard display color, and the wiring indicated by the wiring route 201 has a line width W1.
Therefore, the display color becomes the highlighted display color C1. Furthermore, from this line width W2, the line width W0 for graphic display is
is required.

The graphic display line width W0 and display color C0 thus obtained are sent to the graphic display section 6 and displayed together with the wiring route data, pin data, etc. Next, in the termination determination section 7,
It is determined whether or not all the component pins to be wired have been wired. If the wiring has not been completed, the second input unit 3
Display processing is then performed.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 3 is a block diagram showing a second embodiment of the present invention. As shown in FIG. 3, this embodiment includes an initial display section 8, a first input section 9, a second input section 11, a data storage section 12, a display data processing section 13, a graphic display section 14, and an end judgment section. The design data display section 10 includes a section 15. Further, FIG. 4 is a display example at the time of initial termination according to the present embodiment, and FIG. 5 is a diagram showing a display example (corresponding to FIG. 4) of the execution result according to the present embodiment.

In FIG. 3, the difference between this embodiment and the first embodiment is that an initial display section 8 is provided for displaying pre-registered wiring data on a graphic display section 14. However, other components and operations are basically the same as in the first embodiment described above.

Next, a display example according to this embodiment will be explained with reference to FIGS. 4 and 5.

First, the initial display section 8 reads wired data from the wiring data registration file and displays it on the graphic display section 14. An example of the display is shown in FIG. Here, in FIG. 4, component pins 111 to 1
22, wiring routes 203, 204, 205, 20 are displayed between the respective component pins.
It is assumed that wiring routes 203, 204, and 206 among wiring routes 6 and 207 each have the same line width W3, and wiring routes 205 and 207 each have the same line width W4.

Next, in the first input section 9 shown in FIG. 3, the value of the line width W3 to be highlighted and the highlighting color C are input.
2 is input, and the second input unit 11 reads the registered wiring data from the wiring data registration file, stores it in the data storage unit 12, and displays it in the display data processing unit 1.
3, the display color and line width for display are determined and displayed on the graphic display section 14. The end determination unit 15 determines whether the display of all the registered wiring data has been completed, and if the display of the wiring data has not been completed, the second input unit 11 executes the process again. be exposed. Note that FIG. 5 shows a display example at the time when processing for all wiring data is completed. As is clear in FIG. 5, wiring routes 205 and 2
Since the wiring indicated by 07 is different from the line width W3, the display color is the standard display color, and the wiring routes 203, 20
The wiring indicated by 4 and 206 has the same line width W3 of the emphasis instruction, so the display color becomes the emphasis display color C2.

The graphic display line width and display color thus obtained are displayed on the graphic display section 14 together with the wiring route data, pin data, etc. Next, as described above, the completion determination unit 15 determines whether all the component pins to be wired have been wired, and if not, the second wiring is performed again.
The input unit 11 performs display processing. This second embodiment has the advantage that since the wiring state of wiring with a specific line width can be easily determined on the display screen, it is possible to easily check when changing the line width.
