Abstract

PURPOSE:To shorten processing time and to easily select the optimum connection destination by finding out all the pins of the same network as a selected one pin, and performing the zooming of a window picture so as to display all the found out pins in one picture as many as possible. CONSTITUTION:This system is provided with a means to select an unconnected one pin, a means to find out all the pins of the same net as the selected one pin, and a means to perform the zooming of the window picture so as to display all the found out pins on one picture as many as possible. In other words, when a user selects a pin 23 as the unconnected one pin, the screen zooming of a main window 21 can be performed so as to display all the pins 24-26 of the same net as the pin 23 on one picture as large as possible. Thereby, it is possible to recognize the status of the pins 24-26 of the same net as the net desired to connect and wiring 27-28 at a glance, and to easily select the optimum connection destination also with the elimination of manual working man-hours.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to wiring design for printed circuit boards and integrated circuits,
In particular, it relates to interactive wiring processing on multi-window systems.

[Conventional technology]

Conventionally, in this type of connection support window system, the user instructs the display position and magnification rate to zoom the screen.

[Problem to be solved by the invention]

In the conventional connection support window method described above, the user instructs the display position and magnification rate and zooms the screen, which requires a lot of manual work on the part of the user and takes time to process. Light selection is difficult.

[Means to solve the problem]

The connection support window method according to the present invention has a means for selecting an unconnected pin from information on all nets, a means for identifying all pins of the same net as the selected pin, and a means for displaying all identified pins on one screen. and means for zooming the window screen so that it is displayed as much as possible. Furthermore, there is a means for selecting one point from all the identified pins and points on the existing wiring of the same net, and a means for selecting one point from among all the identified pins and points on the existing wiring of the same net, and a method for displaying the selected one pin and the one point as thickly as possible on one screen. It may also include means for zooming the window screen.Furthermore, it may include means for zooming the window screen with the 1 pin as the center of the screen and at a magnification ratio that facilitates wiring.

[Embodiment] Next, the present invention will be explained with reference to the drawings. Fig. 1 is a flowchart showing a connection support window method according to an embodiment of the present invention. First, in processing box 1, the user's input information is retrieved and one pin from the unconnected pins is selected. Next, in processing box 2, all pins in the same net as the pin selected in processing box 1 are identified. In the processing box 3, the screen of the main window is zoomed so that all the pins identified in the processing box 1 are displayed as large as possible on one screen. Next, processing box 4 takes in the user's input information, and processing box 1 selects a point from among all the pins identified in processing box 2 and points on the existing wiring of the same net as the pin selected in processing box 1. Select one point to connect to pin 1. Next, in processing box 5, the screen of the subwindow is zoomed so that one pin and one point selected in processing box 1.4 are displayed as large as possible on one screen. Further, in the processing box 6, the window screen is zoomed and displayed at a magnification that makes it easy to wire the pin so that the pin selected in the processing box 1 is located at the center of the screen. FIG. 2 is a window diagram immediately after the processing in processing box 3 in FIG. 1 is performed. When the user selects 23 as unconnected pin 1, all pins 2 of the same net as pin 23
The screen of the main window 21 is zoomed so that 4, 25, and 26 are displayed as large as possible on one screen. FIG. 3 is a window diagram showing the result of performing all of the processing in FIG. 1. When the user selects the second fish 29, the screen of the sub-window 22 is zoomed so that the two points (pin 23 and point 29) selected by the user are displayed as large as possible on one screen. Furthermore, the screen of the main window 21 is zoomed at a magnification that makes wiring easier with the 1st pin 23 selected by the user as the center of the screen. A frame 30 indicating the display portion of the main window 21 is displayed in the subwindow 22. Note that in both FIGS. 2 and 3, pins of different nets and existing wiring are omitted. [Effects of the Invention] As described above, according to the present invention, the pins and existing wiring status of the same net as the net to be connected can be seen at a glance, and the connection light can be easily determined. In addition, you can easily know the pins of different nets and the status of existing wiring that exist around the two points you want to connect, which has the effect of eliminating manual labor and making it easier to select the optimal connection light. be.
