Abstract

PURPOSE:To obtain the design rule error contents-display device which can display DRC error contents and a design room check value only by specifying a DRC error. CONSTITUTION:This device is equipped with an error specifying means 2 which specifies an optional design rule error according to design rule visual data 9 generated by visualizing a design rule in layout pattern design and the check result of the design rule, a visual data retrieving means 10 which retrieves the design rule corresponding to the DRC error specified by the error specifying means 2 in the visual data 9, and an error number reference table 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design rule error content display device for visually displaying error content.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional design rule (hereinafter,
Abbreviated as DRC. ) A flow chart showing an error content display device, in which 1 is a design rule check result output when a design rule (hereinafter abbreviated as design rule) in layout pattern design is checked, and 2 is Error designating means for arbitrarily designating an error portion, 3 is a designated DRC error designated by the error designating means 2, 4 is display means for displaying the content of the designated DRC error 3, and 5 is a display for displaying the error content (error message). Is. FIG. 5 is a diagram showing the design rule check result 1. In the diagram,
Reference numeral 6 is an aluminum wiring displayed on the layout pattern and written by a first aluminum reika, 7 is a DRC error display layer written by the design rule check, and this portion is a DRC error portion.

Next, the operation will be described. The design rule check result 1 is directly written in the layout pattern as a DRC error, as shown in FIG. D
The information written as the RC error is the error location, the error message, and the error number. When an arbitrary DRC error is designated in the design rule check result 1 using the error designating means 2, the display means 4 displays an error message (character data) of the error content of the designated DRC error 3 on the display 5.

[0004]

Since the conventional DRC error content display device is configured as described above, the DRC error content display device is
Since the error content is only an error message with character data, if you cannot understand the DRC error content or if you do not know the design rule check value,
Since it is necessary to investigate the DRC error content and the design rule check value based on the design rule standard, there is a problem that the investigation takes time.

The present invention has been made in order to solve the above problems. DRC error contents can be displayed visually by simply designating a DRC error and the design rule check value can be displayed at the same time. The purpose is to obtain a display device.

[0006]

DRC according to the present invention
The error content display device visualizes design rule visual data visualizing the design rule, error designating means for designating the design rule error from the design rule check result, and design rule visual data corresponding to the DRC error designated by the error designating means. It is provided with a visual data search means for searching from among the above and an error number reference table.

[0007]

The DRC error content display device according to the present invention visually displays the design rule check value when the DRC error point is designated, so that the DRC error content and the design rule check value are displayed.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. 1 is a flow chart showing a DRC error content display device according to a first embodiment of the present invention. In the figure, 1 to 4 are the same as the conventional ones, and therefore the description thereof is omitted.
8 is an error number reference table, 9 is design rule visual data (hereinafter abbreviated as visual data) in which design rules are visually written, 10 is designated DRCD
An error content retrieval means for retrieving visual data corresponding to the data 3, 11 is designated visual data corresponding to the designated DRC error 3, and 12 is a display for displaying the designated visual data. FIG. 2 is a data diagram of the designated visual data 11 according to the first embodiment of the present invention. In the figure, 13 is data of designated visual data 11 showing a design rule of the minimum interval between the first aluminum and the first aluminum. Reference numeral 14 is data of designated visual data 11 showing a design rule of a margin between the through hole and the first aluminum end. FIG. 3 is a screen diagram showing a screen display example of the display 12 according to the first embodiment of the present invention. In the drawing, 15 is a screen display of the visual data 11 corresponding to the designated DRC error 3, and 16 is a display screen.

Next, the operation will be described. In the DRC error content display device configured as shown in FIG. 1, when an arbitrary DRC error is designated for the design rule check result 1 using the error designating means 2, the error content searching means 10 causes the designated DRC error 3 to occur. By looking at the error number, which is one of the information of 1., the visual data corresponding to the error number is searched from the error number reference table 8. After the error content retrieval means 10 retrieves, the designated visual data 11 corresponding to the designated DRC error number 3 initially designated is retrieved, and the designated visual data 11 is displayed on the display 12 by the display means 4. A display example in which the designated visual data 11 is displayed on the display 12 is shown in FIG. FIG. 3 shows this D after the DRC error part 7 is specified.
Visual data 11 corresponding to the RC error is displayed as a screen display 15 on the display 12.

Embodiment 2. In the first embodiment, an example of visual data is shown in FIG. 2, but the visual data is D
If you know the RC error content and the design check value, you can use any method.

Embodiment 3. In the first embodiment, the display on the display is shown in FIG. 3, but the visual data may be displayed anywhere.

[0012]

As described above, according to the present invention, design rule visual data visualizing the design rule in the layout pattern design, error designating means for designating an arbitrary design rule error from the check result of the design rule, D specified by the error specifying means
Since the configuration is provided with the visual data search means for searching the design rule corresponding to the RC error from the visual data and the error number reference table, if any DRC error is designated, it corresponds to the designated DRC error. Since the DRC error content design rule check value is visually converted, the DRC error content design rule check value is immediately displayed, which has the effect of facilitating confirmation.
