Embodiment 1
Present embodiment provides a kind of PCB processing method of data, and as shown in Figure 1, this method mainly comprises:
Wherein, this PCB element is meant elements such as device, network, pin, encapsulation, pad, hole, layer; The geometric data of PCB element is meant the geometric substantially data of the PCB element that defines in the PCB raw data file.
Wherein, concordance list is by related each the PCB element of index.
Among present embodiment and the following embodiment, the PCB raw data file is meant the PCB data file that usefulness PCB design software such as research staff is designed, and the PCB data file that obtains after by the method for present embodiment the PCB raw data file being handled is a PCB new data file.
In the method that present embodiment provides, store classifiedly by geometric data and associated data the PCB element, and by related each the PCB element of concordance list, can remove the redundancy in the PCB raw data, and can reduce the time of reading to separate PCB new data file, improve technique effect to the treatment effeciency of PCB data file.
Embodiment 2
Present embodiment specifically provides a kind of PCB processing method of data in conjunction with synoptic diagram shown in Figure 2.
In the method that present embodiment provides, can pass through PCB file conversion instrument, convert the PCB raw data file to PCB new data file, in PCB new data file, the geometric data of each PCB element category is divided, and the PCB element after category is divided is convenient to drawn and control.As shown in Figure 3, this method comprises:
For example: the Extracta in the Allegro software (extraction) function can be from the PCB raw data file of expanding brd by name the geometric data of the PCB elements such as data of extraction device, network, pin, encapsulation, pad, hole, layer in (hereinafter to be referred as the brd file).Can call Allegro software by PCB file conversion instrument, from the brd file, extract the geometric data of PCB circle bundle.
In the present embodiment, can from the brd file, extract the associated data that concerns between the geometric data of PCB element and each the PCB element, thereby produce an output file (being called the val file).The val file is direct readable text, has comprised the associated data that concerns between the geometric data of the PCB element that extracts and each the PCB element.The PCB raw data file that other PCB design softwares produce can change into the brd file of Allegro software earlier by instrument, re-use the method and obtain the val file.
Because the val file is made up of text, and the relation between each PCB element can carry out association by title, so comprise a large amount of repeating datas, causes the val file bigger, resolves also more consuming time when reading.In order to compress the size of val file, improve the PCB data reading speed, need carry out data recombination to the val file.
The method of reorganization is that the geometric data in the val file is classified, classification according to the PCB element, the geometric data of identical element classification is extracted store together to form an element data section, that is: the geometric data of different element classifications will not leave the identity element data segment in.
For example, data segment specifically can be divided into: device data section, pin data section, network data section, layer data section, Line Chart data segment, histogram data segment, circular diagram data segment, arc diagram data section, character and graphic data segment, string data section etc., the concordance list that relation between the different elements is made by the associated data of extracting carries out association, and then realization just can related each PCB element by the index in this concordance list.Concordance list also forms a data segment.These data segments are saved in the file in binary mode and (are called the T3LG file), form PCB new data file.Concrete structure can be with reference to Fig. 4.
For example, device is made up of pin, and pin is made up of basic geometric figure (line, arc, circle, rectangle etc.).The device essential information is kept in the device section, the pin essential information is kept in the pin section, and the associated data that the geometric data of pin is kept at associated data, pin and the figure of Line Chart data segment, histogram data segment, circular diagram data segment, arc diagram data section, device and pin is kept in the concordance list.Device architecture only need write down the index offset address and the pin number of pin, and pin configuration only need write down the index offset address and the figure quantity of the fundamental figure that comprises.When drawing a device, can navigate to pin fast according to the pin index offset of record, navigate to fundamental figure fast according to the fundamental figure index offset that pin configuration write down again, just can draw then.PIN_OFFSET=200 as a device among Fig. 4, PIN_COUNT=2, then can from concordance list, obtain the index 1345,1589 of two pins that comprised fast, get access to pin data according to the pin index, according to the LINE_OFFSET and the LINE COUNT of pin data, can find the rectilinear figure data that comprised fast again then.In fact this associative search process is the value of array or pointer, and speed is very fast.Pass through such processing simultaneously,, can represent with isometric structure although different with the data bulk that geometric data comprised of element classification.
Character string is also unified preserves with string segments, and the structure that comprises character string only writes down the index of this character string.For example certain device name is " U170 ", index in string segments is 1200, then this device only needs recording indexes 1200, other all comprise that the structure of character string " U170 " all only needs recording indexes 1200, can directly obtain the address of character string when reading according to index and skew.The character string that repeats is so only preserved once, can reduce file size.
Because the PCB new data file of val form is a binary file, and passed through the classification segmentation, set up incidence relation between each section by index segment, in can reading into memory the PCB data file of this T3LG form fast when therefore drawing the PCB figure, need not to resolve again, significantly improved the rate of loading of PCB data.
In the present embodiment, establish the expansion T3L (hereinafter referred to as the T3L file) by name of the PCB new data file of this process encryption.
