Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings
It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
Embodiment
As shown in Figure 1, the embodiment of the invention provides a kind of method of adjacent layer cabling angle in inspection PCB design, institute
The method stated includes:
Step 1: calling skill program, frame selects inspection area.
In the step, for calling skill program, used principle are as follows:
Firstly, loading skill program in Allegro software.The concrete operation method of the step are as follows: soft in Allegro
Skill load (" check_outline.il ") is inputted in the order line of part, wherein check_outline.il is skill journey
The source files of program of sequence.
Secondly, skill program is called in Allegro software, method particularly includes: check_ is inputted in order line
outline.Wherein, check_outline is program command, this operation calls program.
In step 1, frame selects inspection area method particularly includes: opens the design drawing where inspection area, selects work using complete
Tool or frame selection tool select inspection area as operation object.The full editor of selection tool or frame selection tool from Allegro software
Function also can use skill program and call directly.
Step 2: all cablings in inspection area are grabbed by being arranged；
All cablings in capture area method particularly includes: firstly, the type for allowing to choose in all object types is arranged；
Then, the type chosen is selected in type is line segment allowing to choose；Finally, object is selected to grab line segment entirely.
Step 3: the cabling intersected in crawl adjacent two layers；The specific implementation process of step 3 are as follows:
The line segment of all crawls: being generated different set according to layering by S31, title of each set comprising place layer with
And this layer line segment title for including and coordinate.
S32: being layered any two adjacent set, marks line segment using different colors, in identity set
Line segment is marked using same color.
S33: traversing all line segments, finds that all there are the nodes of two kinds of colors.In a practical situation, it is also possible to occur
Nodes more than two kinds of colors illustrates that three even more cablings intersect on the same point, at this point, according to the step of this programme
Suddenly, all colours of the node are actually split into the form of combination of two, however, it is desirable to it is noted that only be layered
Adjacent combination of two is only effectively.
S34: due to having been realized in the fractionation two-by-two in color in step S33, as long as crawl node corresponding two
Cabling.It should be noted that corresponding two cablings of each node are required to individually grab.
Entire step 3 is and to grab intersection line segment for judging whether line segment intersects, and angle angle can just be calculated by only intersecting
The too small situation of extended line angle can be quoted and, not meet our check gauge if not judging whether line segment intersects by degree
Then.
Step 4: using slope, successively calculate the angle between each group of two layers of intersecting trace, obtain all adjacent layer intersections
The included angle of cabling.
Step 5: the angle value calculated is judged, if angle value less than 30 degree, highlights the cabling.
As shown in Fig. 2, the embodiment of the invention also provides a kind of device of adjacent layer cabling angle in inspection PCB design,
The device includes selecting module, the first handling module, the second handling module, computing module and judgment module.
The selecting module selects inspection area for frame, is made using full selection tool or frame selection tool selection inspection area
For operation object.
First handling module is operation object by the line segment in setting inspection area, grabs in inspection area
All cablings.
Second handling module for judging whether line segment intersects, and grabs the cabling intersected in adjacent two layers, only intersects
Included angle can be just calculated, if not judging whether line segment intersects, the too small situation of extended line angle can be quoted and, do not met
Our inspection rule.
The computing module, receives the cabling that the second handling module grabs, and calculates two layers of intersecting trace using slope
Between angle.
The judgment module, the angle value for judging to calculate, highlights the cabling if angle value is less than 30 degree.
For embodiment, in practical applications, for entire step process by skill program, the process of execution is as follows:
1) software load and calling are carried out, firstly, inputting skillload in the order line of Allegro software
(" check.il "), wherein check.il is source files of program, this operation loading procedure；Secondly, being inputted in order line
Check, wherein check is program command, this operation calls program；
2) frame favored area is checked automatically；
3) problematic cabling is highlighted out, can check one by one.
Although specification and drawings and examples have been carried out detailed description to the invention, this field skill
Art personnel should be appreciated that and still can be modified or replaced equivalently to the invention；And all do not depart from wound of the present invention
The technical solution and its improvement for the spirit and scope made, are encompassed by the protection scope of the invention patent.
