Description
Technical Field
The invention relates to the technical field of PCBs, in particular to a method, a system, a storage medium and equipment for detecting silk-screen text overlapping.
Background
When designing a PCB (Printed Circuit Board) using Allegro software, a kind of PCB design software, it is required that there is no overlap between silk-screen texts for readability of the PCB design. At present, the silk-screen text overlap is mainly detected through manual measurement, or the measurement is carried out by calling a measurement function carried by software. Manual inspection of silk-screen text overlap is time-consuming and labor-consuming, and may be omitted; the function measurement carried by calling software has a certain problem because each silk-screen text has an outer frame (the outer frame cannot be displayed on the silk-screen layer but actually exists), and the function judges whether the silk-screen texts are overlapped by measuring the distance between the outer frames of the silk-screen texts. Fig. 1 shows a schematic diagram of the overlap between outline frames of silk-screened text in the prior art. As shown in fig. 1, two silk-screen texts "R345" and "C567" are not overlapped, but the outer frames of "R345" and "C567" are overlapped, so in the prior art, a function measurement carried by software itself will obtain the result of overlapping the two silk-screen texts.
In the PCB design, a silk-screen text can be attached to the position near each component, and if the PCB area is required to be small and the arrangement among the components is compact, the inspection mode of overlapping the silk-screen texts in the prior art can enable the silk-screen to occupy larger PCB area.

and converting each text element of each silk-screen text into a plurality of line segments through an axlText2Lines function respectively and attributing the line segments to respective number series.
6. The method of claim 1, wherein combining all line segments in each series into a shape of a corresponding text element to obtain a single text shape comprises:
all line segments in each array are combined into the shape of the corresponding text element by the axlPolyFromDB function to get a single text shape.
7. The method of claim 1, wherein combining the single text shapes corresponding to each text element in each silkscreen text into silkscreen text shapes comprises:
and combining the single text shapes corresponding to the text elements in each silk-screen text into silk-screen text shapes through an axlPolyoperation function.
8. A system for inspecting silk-screened text overlay, comprising:
the line segment conversion module is configured to acquire all silk-screen texts on a preset silk-screen layer in a circuit board design drawing, convert each text element of each silk-screen text into a plurality of line segments respectively and attribute the line segments to respective number columns so as to obtain a plurality of number columns corresponding to each silk-screen text;
the combination module is configured to combine all line segments in each array into shapes corresponding to the text elements to obtain single text shapes, and combine the single text shapes corresponding to the text elements in each silk-screen text into silk-screen text shapes to obtain the silk-screen text shapes corresponding to all the silk-screen texts;
