Abstract

PURPOSE:To improve the efficiency of interactive wiring processing by displaying only the rat nest of a corresponding unconnected pin pair when the unconnected pin pair is selected. CONSTITUTION:An all rat nest display control part 2 displays an unconnected wire on the basis of information recognized by an all unconnected pin pair recognizing part 1, and when the unconnected pin pair is selected and instructed from among those, an instructed coordinate recognizing part 3 recognizes the coordinate position of an instructed point. An instructed unconnected pin pair recognizing part 4 recognizes the unconnected pin pair, and an instructed rat nest display control part 5 displays only the rat nest of the recognized unconnected pin pair. Then, unconnected wire connecting processing is executed interactively, and when connection results in success, a connection recognizing part 6 recognizes a connected situation, and an instructed rat nest non-display control part 7 erases the rat nest display of the corresponding unconnected pia pair. Thus, the interactive wiring of the unconnected wire can be processed efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an OAD system, more specifically, an LSL
, relates to an unconnected line display method suitable for interactive wiring processing of printed circuit boards.

(Prior Art) Conventionally, this type of unconnected display method displays the entire rat nest to notify the unconnected state during interactive wiring processing.
The target bin pair was selected by the operator indicating a point in the bin pair to which the operator wanted to connect.

However, even after one selection was made, the entire rat nest was displayed in the same state as before the selection.

(Problem to be solved by the invention) Therefore, when there are many unconnected pin pairs, the undelivered line displays overlap, and when performing wiring processing after selecting the pin pair to be processed for wiring connection, the entire display of unconnected pin pairs is 9. This has the drawback of significantly reducing the efficiency of interactive wiring processing.

The object of the present invention is to overcome the above-mentioned drawbacks.

To provide an unconnected line display method that prevents one screen from being displayed in an unnecessary manner by displaying only unconnected pin pairs, and efficiently processes unconnected dialogue wiring. It is in.

(Means for Solving the Problems) In order to accomplish the above object, the unconnected display method according to the present invention is such that in the t method for displaying the connection status of LSIb and printed circuit board, the connections t7'l: of all pin pairs are unconnected. Wiring condition? : All unconnected pin pair recognition unit to recognize, all rat display control unit to display unconnected on the display unit based on the information recognized by the all unconnected pin pair recognition unit, and the pointing point of one selected unconnected pin pair. an instruction coordinate recognition section that recognizes the coordinate position of the instruction point, an instruction connected pin pair recognition section that recognizes the unconnected pin pair from the coordinate position of the specified point, and an instruction that displays only the two nests of the recognized unconnected pin pair on the display section. A rat nest display control section, when a connection is successful as a result of interactively performing the unwired connection process M, a connection recognition section that recognizes the connection status, and a rat nest display section that displays the result of the connection recognition. reflected in the display.

and a rat nest non-display control section for instructing to delete the corresponding unconnected pin pair from the display section, and only the designated unconnected pin pair is displayed in the rat nest.

(Example) The present invention will be explained in more detail below with reference to one drawing.

Figure 1 shows an ORT to which the unconnected display method according to the present invention is applied.
An example of a screen display is shown.

Figure (a) shows an unconnected pin pair)! FIG. 3B is an example of the display after selecting the unconnected pin pair.

FIG. 2 is a block diagram showing the configuration of the unconnected line display method according to the present invention.

First, the all-unconnected pin pair recognition unit l gm the connected or unconnected status of all pin pairs.

Next, the all rat nest display control section 2 displays an unconnected pin pair based on the information recognized by the all unconnected pin pair recognition section 1.

Then, an unconnected pin pair is selected from among these, and when instructed, the indicated coordinate recognition unit 3 recognizes the coordinate position of the indicated point. The designated unconnected pin pair recognition unit 4 recognizes unconnected pin pairs from the coordinate position of the designated point. Next, the designated rat nest display control section 5 displays only the rat nests of the recognized unconnected pin pairs.

Then, looking at this display, the unconnected connection process is performed interactively, and when the connection is successful, the connection recognition section 6 checks the connection status.

Instructions to hide the rat nest! The II control unit 7 reflects the result of the connection recognition and erases the rat nest display of the corresponding unconnected pin pair.

Next, a detailed explanation will be given using FIG. 1.

First, when entering the interactive wiring process, all unconnected pin pairs are displayed by the all unconnected pin pair identification unit 1 and the total 2 net nest display control unit 2 as shown in FIG. 1(a).

Next, the operator selects an unconnected pin pair for which connection is desired, and in this example, it is assumed that point A of unconnected pin pair 11 is designated.

As a result, the designated coordinate recognition section 3 recognizes the coordinate position of point A, and based on the coordinate position, the designated unconnected pin pair tiitm section 4 recognizes which unconnected pin pair has been designated.

Further, based on this recognition result, the instruction rat nest display control section 5 displays only the corresponding unconnected pin pair A-B on the CRT screen (as shown in bl).

Thereafter, in the display state of (b), when the unconnected pin pair 110 of interest is successfully wired in the interactive wiring process, the wire connection recognition unit 6 recognizes the state.

Then, the designated rat nest hiding control section 7 erases the rat nest display of the corresponding unconnected pin pair 11, and returns to the overall display shown in FIG. 1(a) for the remaining unconnected pin pairs.

This work is completed by repeating the above work for all unconnected pin pairs.

(Effects of the Invention) As explained above, the method of the present invention does not always display the entire rat nest display of unconnected pin pairs during interactive wiring processing, but when an unconnected pin pair is selected,
Since it is configured to display only the rat nest display of the unconnected pin pairs of this amount, there is an effect that the efficiency of the interactive wiring processing can be greatly improved.
