Description
Technical Field
The present invention relates to the field of EDA, and in particular, to a method for recovering a design drawing, an electronic device, and a storage medium.
Background
In the production of PCBs, there are currently two processes, one is a positive process and one is a negative process. Wherein in the positive design, the pattern of the copper layer is the same as the final desired circuit board pattern. That is, the copper layer pattern in the feature is the actual circuit on the circuit board. The negative is diametrically opposed to the positive, and in the negative design, the pattern of the copper layer is opposite to the final desired circuit board pattern. That is, the copper layer pattern in the negative design is a blank area on the circuit board, not the circuit.
When a circuit pattern on a layer of a PCB is desired to be produced in a negative process, the EDA tool outputs the "what you see is what you get" circuit design in a "negated" manner, i.e., outputs negative data as production data. After the production data is obtained, verification is required at the manufacturing stage, and the production data may be trimmed during verification. In order to quickly obtain what adjustments the user made, the modified production data is currently imported into the restoration design drawing by the EDA tool, and then the modified design drawing is compared with the original design drawing to obtain a modified part. The specific process of the EDA tool for importing the modified production data into the restoration design drawing comprises the following steps: and directly importing the modified production data into a restoration design drawing after taking the complementary data, namely taking the complementary data of the die copper sheet and the die hole in the production data by an EDA tool. In the process of taking the complementary data, an error may occur to cause a wrong design diagram to be recovered, for example, an outer frame in the production data may be taken as a hole to take the complementary data by mistake, and further, the data of other mold copper sheets and mold holes may be disordered to generate the wrong design diagram. The erroneous design is compared with the original design, and the obtained comparison result is also erroneous. There is therefore a need for a method that enables the correct importing of production data into an EDA tool to generate a correct design drawing.

Fig. 1 is a flowchart of a method for recovering a design chart according to an embodiment of the present invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Referring to fig. 1, a flowchart of a method for recovering a design drawing, the method includes the following steps:
s100, acquiring production data, wherein the production data comprise a plurality of die copper sheets and die holes, and each die copper sheet and each die hole are configured with area coordinates.
After the original design is designed, the design desired to be produced by the negative process is derived and generated as a negative design, and production data is obtained. In the production and manufacturing process, production is required according to production data in the negative film design drawing, and the production data can be finely adjusted according to actual conditions before production so as to meet corresponding conditions. When it is necessary to know what content has been adjusted in the production stage, the adjusted production data needs to be reintroduced into the EDA tool, and then compared with the original design drawing to obtain a difference portion, which is the adjusted content.
The production data and the design data are in complementary relation, the design copper sheet in the design data is a die hole in the production data, and the design hole in the design data is the die copper sheet in the production data. The production data is generated by the EDA tool after the EDA tool takes the reverse from the design data.
Wherein the pattern of copper sheets or holes is generally a regular pattern, e.g. polygonal or circular, etc.
When the copper sheet or the hole is polygonal, the area coordinates of the copper sheet or the hole are the coordinates of each vertex of the polygonal outer frame. When the copper sheet or the hole is circular, the area coordinates of the copper sheet or the hole are the center point coordinates and the radius length of the circle.
Optionally, the production data is stored in a file in xml format.
It should be noted that, in the embodiment of the present invention, the production data and the design data originate from the source program.
And S200, analyzing the production data to obtain all the die copper sheets and all the die holes, and the area coordinates of each die copper sheet and each die hole.
When analyzing the die data, generating a grammar tree, wherein each die copper sheet and each die hole are respectively a node in the grammar tree, and the attribute of each node comprises a node type and a coordinate attribute, wherein the node type can be a type label of the die copper sheet or a type label of the die hole, and the coordinate attribute is the area coordinate of the current die copper sheet or the current die hole. And searching the node types of the grammar tree according to the node types of the mould copper sheets to obtain the nodes of all the mould copper sheets. Similarly, when the data block is analyzed, node types of all the die holes in the grammar tree are the same, and node types of the grammar tree are searched according to the node types of the die holes to obtain nodes of all the die holes.
S300, resetting all the die copper sheets to design holes respectively, and resetting all the dies Kong Chongzhi to design copper sheets.
Wherein the types of the copper sheet and the hole are reset in this step, in order to convert the production data into the design data by using the complementary relationship between the production data and the design data.
When the type of the die copper sheet of the node is reset to the type of the design hole, the coordinate attribute of the node is unchanged. For example, the type of the current node before the reset is the mold copper sheet and the area coordinate is a, and the type of the current node after the reset is the design hole and the area coordinate is a.
In the original design data, the corresponding region coordinates are already allocated to each copper sheet and each hole, respectively. Therefore, the patterns visually overlapped in the design drawing of the design data are actually independent region coordinates in the production data and the design data, and do not interfere with each other.
As a preferred embodiment, the outermost mold copper sheet is extracted and the outermost mold copper sheet is replaced as the design frame. Optionally, the step of extracting the outermost mold copper sheet includes: and extracting the maximum area coordinates of all the die copper sheets, wherein the die copper sheet corresponding to the maximum area coordinates is the die copper sheet of the outermost layer.
S400, obtaining the design copper sheet containing each design hole according to the containing relation among the region coordinates, binding the design holes with the containing relation and the design copper sheet into a whole element, and obtaining design data of a plurality of design copper sheets with the design holes.
Wherein, a whole element binds a design copper sheet and K design holes, wherein K is more than or equal to 0. The relationship between the various types of design copper sheet and design holes is included in the design data, for example, one design copper sheet includes one design hole, or may include a plurality of design holes.
The algorithm for obtaining the design copper sheet containing each design hole according to the containing relation among the region coordinates is graphic operation.
Optionally, the algorithm for obtaining the design copper sheet containing each design hole according to the inclusion relation between the region coordinates comprises the following steps:
s420, judging whether the outer frames of the design copper sheet and the design hole are intersected according to the region coordinates, and judging that the outer frames have no inclusion relationship if the outer frames intersect; otherwise, S440 is performed.
It should be noted that when there is an intersecting relationship between two polygons, one of the polygons has two vertices, one inside the other polygon and one outside the other polygon. Therefore, whether an intersection relationship exists between two polygons or not can be judged through the magnitude relationship between the abscissa and the ordinate of the region coordinates.
S440, judging whether the region coordinates in the design holes are in the outer frame of the design copper sheet, if so, the design copper sheet comprises the design holes; otherwise, the two have no inclusion relationship.
Other algorithms in the prior art for determining the inclusion relationship between two different region coordinates fall within the scope of the present invention.
Wherein, an integral element includes a design copper sheet and a design hole, and the region of design copper sheet is greater than the region of design hole, and the pattern that actually forms is the difference of design copper sheet and design hole, namely removes the copper sheet region after the design hole in the region of design copper sheet and be the circuit area of hopefully.
As a preferred embodiment, the S400 further includes: when the region coordinates of the ith design hole are contained by the region coordinates of the candidate plurality of design copper sheets, a minimum bounding box of the region coordinates of the candidate plurality of design copper sheets is obtained, and the design copper sheet corresponding to the minimum bounding box and the ith design hole are bound into a whole element.
S500, visually displaying all the design data, and recovering the design drawing.

In summary, the embodiment of the present invention provides a method for recovering a design drawing, which includes analyzing and obtaining a mold copper sheet and a mold hole in production data, resetting the mold copper sheet to be a design hole, resetting the mold Kong Chongzhi to be a design copper sheet, obtaining a design copper sheet including each design hole by calculating a inclusion relation between coordinate areas, binding each pair of design holes and the design copper sheet to be an integral element, obtaining design data, and visualizing all the design data to recover the design drawing. After the copper sheet and the hole are reset, the relationship between the copper sheet and the hole is bound through the inclusion relationship between the region coordinates, so that the situation of incorrect recognition of the copper sheet and the hole is avoided, and the correct design diagram is recovered.
