Abstract

PURPOSE:To remove the defect of a circuit due to wiring length prior to manufacture by executing the check of the designated wiring length and the input wiring length of an objective pin pair at the time of interactive wiring, and highlight-displaying an error when the input wiring length exceeds the designated wiring length. CONSTITUTION:At the time of the interactive wiring, an input wiring length check part 4 checks the designated wiring length of the objective pin pair and a wiring plan at the point of time of input during connection connecting work at real time. Then, when the input wiring length exceeds the designated wiring length, an error path highlight part 5 displays this whole wiring path by changing its color. Thus, the defect of the wiring length exerting influence on the operation of the circuit is removed, and the normal operation of a product is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an interactive wiring device for interactively wiring a 1-78■ or a printed wiring board in a CAD system.

[Conventional technology]

In the CAD system, especially LSI and printed wiring boards (
Conventional interactive wiring methods for wiring to PWBs tend to place emphasis on terminal connection processing, and various improvements have been made for this purpose, or there is no need to worry about the impact on circuit operation. The wiring length is hardly checked.

[Invention or problem to be solved]

For this reason, with conventional interactive wiring methods such as "double wiring," even if a considerable amount of man-hours are spent to complete the wiring, there is no guarantee that the connected wiring will have any circuit problems. If the wiring length is such that a problem occurs in any path, there is a drawback that the product cannot operate normally as a result.

[Means to solve the problem]

The interactive wiring device of the present invention includes an error display mode switching unit that switches the display when the input wiring length exceeds the specified wiring length during the end connection work of the target bin pair, and an end connection display unit that displays the end connection pin pair. a wiring length display section that displays the specified wiring length of the target bin pair and the current length during connection work; an input wiring length check section that checks the current length at the time of input in real time; an error path highlighting section that displays the entire wiring path in a different color when the specified wiring length is exceeded; and an input point rejection section that rejects the last input point when the input wiring length or specified wiring length is exceeded. It is equipped with

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Figure 2 shows the CR in the wiring length display section of one embodiment of Figure 1.
The 21st J(a> is the display column of the bin pair (A to Z) to be wired and its terminal connection display, the designated wiring length and the current wiring length, and the 21st J(b) and (
The parentheses are a display column showing path errors at points A, . FIG. 1 is a block diagram showing one embodiment of the present invention.

The embodiment shown in Fig. 1 includes an error display mode 1-' switching section which switches the error display when the specified wiring length is exceeded during the end-connection work of the anti-insect pin pair, and an end-connection display which displays the end-connection pin pair. part 2, a wiring length display part 3 that displays the designated wiring length of the imaginary pin pair and the current length at the time of input during connection work, and an input wiring length check part that checks the actual wiring length at the time of input in real time. 4, an error path highlighting section 5 that displays the entire wiring path in a different color when the input wiring length exceeds the specified wiring length;
Input point rejection unit 6 that rejects the last input point that caused the overage when the input wiring length or designated wiring length is exceeded.
The error path highlight 1 part 5 and the input point rejection section 6 are selected by switching the error display mode 1 to the switching section 1.

The embodiment shown in FIG. 1 will be described in more detail with reference to FIG. 2.

First, when the highlight display of the error path is selected by the error display mode switching unit 1, points A to E are the target bin pair, and the state in which points A to E are wired is displayed as the second
Display as shown in Figure (a). In this example, the manual wiring length exceeds the specified wiring length at point E, and the wiring length display section 3 displays the specified length and the current length indicating the current wiring length in real time l\ (9 reference code 13 ). Furthermore, since the input wiring length exceeds the specified wiring length,
), the entire path from point A to point E is displayed on highlight 1 in a color that can be seen at a glance. FIG. 2(c) is a display example when input point rejection is selected in the error display mode switching unit 1, and shows that input points A to E are being input.

At this time, if the input wiring length check unit 4 detects that the input wiring length exceeds the specified line length at the time of inputting point E, the input point rejection unit 6 operates to pass the point 0 to point E. or be rejected.

〔Effect of the invention〕

As explained above, the interactive wiring device of the present invention checks the specified wiring J (and input wiring length) of the target pin pair during interactive wiring, and when the input wiring length exceeds the specified wiring length, an error is raised. By displaying the following information,
This has the effect that circuit defects due to wiring length can be eliminated prior to manufacturing.
