Abstract

PURPOSE:To easily design oblique wiring and easily make a plan for nonwiring correction by facilitating the free rotation and inversion of substrate data without altering data structure. CONSTITUTION:This substrate data display system is equipped with a display direction indicating means 11 which sets the display direction of the substrate data and whether or not the data are inverted, a means which finds display coordinates on an output device such as a display unit, and a coordinate correcting means 13 which refers to the set values set by the display direction setting means 11 and makes corrections so that the substrate data are rotated or inverted around the center position of the screen as an origin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board data display system.

[0002]

2. Description of the Related Art Conventionally, when the board data is displayed on the screen, the board data displayed on the screen is basically fixed in the X and Y directions. When viewed from the back of the board, X
Alternatively, the screen in which the board data is reversed may be displayed by reversing the Y axis.

[0003]

The conventional board data display system has a problem that it is difficult to input the coordinate position of the end point or pick up the coordinate position when designing the diagonal wiring pattern. In addition, when considering a wiring strategy such as uncorrected correction, it is necessary to look at it from various angles and make a strategy, but the display screen has the Z and Y axes fixed.
Alternatively, there is a problem that it takes time to make a strategy because the display can be changed only by reversing the substrate.

[0004]

The board data display system of the present invention is a display direction setting means for presetting the display direction and the presence / absence of inversion of board data in an application that supports the design of a printed wiring board. Coordinate correction that refers to the means for obtaining the coordinates to be displayed on the output device (screen) and the set value set by the display direction setting means, and performs correction such that the board data rotates or reverses with the screen center position as the origin. And means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. First, the board data 21 to be displayed is loaded into the application 1. Screen display means 12 for graphically displaying the board data prepared in the application 1
Thus, the board data 21 is graphically displayed on the output device 22. Also, when displaying the reverse screen,
The coordinate correction means 13 corrects the X coordinate or the Y coordinate. In the present invention, the display direction of the board data and the presence / absence of inversion can be set, and the display direction indicating means 11 for storing the setting result in the display direction variable 31 and the coordinates displayed on the screen before being sent to the output device 22, With reference to the display direction variable 31, a coordinate correction means 13 is added to correct the coordinates so that the board data is rotated and inverted with the screen center position as the origin.

Next, the display result obtained by the present invention will be described with reference to FIGS. 2 and 3.

In FIG. 2, a substrate 41 having diagonal wiring exists.
A display range 42 that is a part of the above is displayed on the output device 22. Since the display direction instructing means 11 instructs the substrate 41 to be displayed in the 0 degree direction, the substrate data is X, Y.
It is displayed on the output device 22 according to the axis.

In FIG. 3, the display direction instructing means 11 displays 9
When it is instructed to rotate in the 0 degree direction, it is considered that the entire area of the substrate 41 is tilted in the 90 degree direction.
However, since the display range 42 is fixed, the coordinates are corrected so that the horizontal pattern and the vertical pattern are interchanged, and the result is displayed on the output device 22. Here, the reason why the display range 42 is fixed is that the shape and size of the display range 42 are determined by the display performance of the output device 2. In FIG. 3, the 90-degree rotation is taken as an example, but it is easy to add various calculation processes such as an arbitrary angle and inversion in the coordinate correction means 13.

[0010]

As described above, the present invention has an effect that diagonal wiring can be easily designed by freely rotating and reversing the substrate data without processing the data structure. In addition, since the board can be viewed from various angles, there is an effect that a strategy of a correction method in the case of undistributed correction can be easily performed.
