Embodiment
Fig. 1 has shown that is used for implementing a computer of the present invention.Computer has a processor, and it is connected with memory by bus, also connects input/output interface by bus simultaneously.Memory storage circuit printing plate design program.Input/output interface connects keyboard, external memory storage and display, and circuit printing plate figure shows by display, perhaps output equipments such as the printer output by being connected with computer.
Owing to need satisfied requirement simultaneously from aspects such as technology, production, debugging, standards by the device identification among the circuit printing plate figure of computer installation generation, through abstract processing, after being transformed into these requirements in printed circuit board (the being called for short PCB) design, the putting position of requirement device identification can be in the custom position of common manual setting, and the concrete requirement of putting device identification is:
(1) device identification is not far apart from related device, because apart from the fork meaning that causes that easily identification is affiliated too far away;
(2) the not pad, device body, on-line testing of covering device (in-circiuttest, test point ICT), other literal (must satisfy) as far as possible can not cover on the via hole (nonessential satisfy) of device identification;
(3) angle, direction are conformed to the standard and are accustomed to;
(4) consideration that is designed beautifully makes the font of all device identification into unified specification.
The PCB design is a kind of planar design, especially puts the work of device identification.All objects all have (comprising device, via hole, literal etc.) drop shadow spread of a maximum in the PCB design, are referred to as object bounds, and in the PCB design of having finished, except device identification, the position of other object is all fixed.So satisfying under the prerequisite of above-mentioned some requirement, in fact the problem of putting device identification can be converted into such processing requirements:
(1) object bounds of device identification is controlled apart from the distance of the object bounds of related device;
(2) object bounds of device identification does not overlap with the object bounds of other objects;
(3) object bounds angle, the direction of device identification are suitable;
(4) the object bounds height unanimity of device identification, but different because the length of character string is different.
String attribute by device identification, its object bounds must be a rectangle, and may there be shapes such as circle, ellipse, triangle in other objects on the pcb board, and for shortcut calculation is converted into rectangle with all non-rectangle borders, the problem description of so final formation is as follows:
On plane with known dimensions, there is the rectangle of some fixed positions, other rectangle to be positioned is arranged, need in this plane, seek foothold, requirement is satisfied not with the rectangle that has existed and is found the rectangle generation to be positioned border of foothold to overlap recently.Simultaneously, having existed in each rectangle to be positioned and the plane has man-to-man dependency relation between the rectangle, exists the distance between the rectangle of dependency relation can not be far away excessively, and the standard of judgement is to conform to the standard and be accustomed to.
Consult shown in Figure 2, method of the present invention is, read the character string information that is used for device identification earlier, and the attribute of character string handled to satisfy the sign direction and the font of regulation, around device, determine an identified areas series that constitutes by a plurality of candidate identification subregions then, last therefrom definite suitable candidate identification subregion of putting device identification, and in this sign subregion generation device identification.
Be elaborated below in conjunction with the realization of accompanying drawing to said method:
Handle direction and font: the design document of PCB design software Allegro has adopted a kind of structure of object tree to come stored information, and each object all has the attribute of oneself.The device label is exactly in this object tree, can revise the direction and the font of device label easily by the attribute of revising the device label.The Skill language provides visit and has revised the interface of all objects in the object tree, and the programming by the Skill language is the direction and the font of processing apparatus label easily.
Seek the correct position of device identification and consult flow process shown in Figure 6:
When determining the correct position of device identification, dodge priority and device identification to the distance of device as necessary input parameter, can also can provide default value by the input equipment input of computer installation by computer installation.
Dodge priority: in the PCB of reality design, in order to make device identification can be relatively easy to identification, the actual conditions of putting according to the device label, need device identification that these objects are dodged (not covering), comprise: device body, pad, ICT test point, other literal, via hole, here the priority of having dodged has as required been arranged from high to low, sees the following form.
| Priority | Device body | Device bonding pad | The ICT test point | Other literal | Via hole |
| ????0 | ????Y | ||||
| ????1 | ????Y | ????Y | |||
| ????2 | ????Y | ????Y | ????Y | ||
| ????3 | ????Y | ????Y | ????Y | ????Y |
| ????4 | ????Y | ????Y | ????Y | ????Y | ????Y |
The explanation device identification needs the priority of the object of dodging out in the table in PCB design.For example, when priority parameters is 4, objects all in the his-and-hers watches being dodged, is 3 o'clock, will ignore the existence of via hole, and the rest may be inferred.The strategy of selection priority can be very flexible in the reality.
Device identification is to the distance of device: refer to the minimum distance of device identification projection rectangle to the device projection rectangle, be illustrated in fig. 3 shown below, wherein the distance of device identification D6 and device is d.
Seek suitable position and solve " rectangle COINCIDENCE PROBLEMS on the plane " exactly.This function is made a module, dodge priority and device identification and arrive two input parameters of the distance of device as this module, the coordinate that is output as the rectangular area that can correctly put device identification is illustrated in fig. 4 shown below (coordinate of rectangular area is right: lower left corner coordinate and upper right corner coordinate).
In a PCB design of having finished, other such as via hole, device, literal except that device identification etc. all has fixing position, and corresponding device identification of each device, always wish that device identification can try one's best apart from its corresponding device more closely, so just produced the input parameter of a device identification apart from the device distance.Size (can from the PCB design document, directly read) according to this parameter and device identification character string itself, can around relevant device, calculate a rectangular area series, N different rectangle arranged in this rectangular area series in theory, whether in these rectangular areas have the suitable rectangle of putting device identification, find the back just device identification to be moved over and get final product if judging then.In order to simplify calculating, the faster procedure speed of service, and the actual conditions that combine PCB design, do not need to carry out so many judgement, only need to judge just the going up of rectangular area, device position, a positive left side, just down, four rectangular areas, the right side suitable getting final product whether just.
Fig. 5 has illustrated the schematic diagram of candidate's device identification rectangle series: wherein d is the distance of input parameter device identification apart from device, the rectangular area of four solid lines in upper and lower, left and right is zones that program is made judgement in the reality, and the rectangular area of dotted line is all rectangular areas that can calculate the position.
Obtaining afterwards through the candidate rectangle of simplifying regional serial (only comprising four rectangles in upper and lower, left and right), then according to dodging the priority parameters input, judge in above-mentioned four rectangular areas whether have the rectangle that is fit to put device identification, device identification is moved over get final product then.(also have a kind of situation to be: through judging that above-mentioned four candidate rectangle zones all are not suitable for putting device identification, the processing of this situation will provide processing method in the related description below.) workflow such as figure below that this module is concrete:
Because PCB design is ever-changing, so realize on the pcb board that it itself is a very complicated problems that the Automatic Program of device identification is put.The present invention has well solved the problem that device identification is put automatically in the PCB design, but running into the very high or pcb board local density of device density when very high, can go out the situation that four candidate rectangles all are not suitable for putting device identification, solution is by program device identification to be moved to the center of its related device and this device of highlighted demonstration, then by the manual setting position.Because this situation has negligible amounts, adopting this solution also is very economical.
Can repeatedly carry out method of the present invention to same printed circuit board figure by computer installation, each by importing the different numerical value of dodging priority and device identification and device distance parameter, arrive different control effects, common PCB design, after carrying out 2～3 times, basically do not need to adjust by hand again, satisfy the requirement of standard and custom fully.
