Embodiment
Basic thought of the present invention is: utilize device in the component inventory and the circuit in the modular design printed circuit board (pcb) in the module library, after circuit design is finished, extract the sub-design circuit in the designed circuit, the generation module circuit file, and deposit the modular circuit file that is generated in module library as module.
Fig. 1 is the schematic flow sheet that the present invention realizes the method for portable multiplexing of printed circuit board, and as shown in Figure 1, this method may further comprise the steps:
Step 101 is associated with component inventory and module library with eda software, and derives the net table from schematic diagram;
Concrete, described eda software can be the PCB design software Allegro of Cadence company, the software that the principle diagram design software Concept HDL of Cadence company, the PCB design software Expedition of mentor company etc. are commonly used, in the present embodiment, use is Concept HDL and allegro software;
Usually, each eda software all can have corresponding devices storehouse and module library, that is to say, each eda software can be associated with component inventory and module library, described eda software is associated with component inventory and module library, related method is: the address path of component inventory and module library is filled in the relevant option of eda software; In allegro software, described relevant option is " design path ", finish association after, eda software just can call device and module from component inventory and module library;
The described net table of deriving from schematic diagram is: derive the net table from the schematic diagram of the printed circuit board (PCB) that will design, specifically how to derive the net table and belong to prior art.Such as, at the derivation process of Concept HDL software specifically: click " export physical " button in the Concept HDL software, the Chinese meaning of export physical is to derive the net table, in the window that ejects, choose suitable option, click " OK " button, can realize the derivation of net table; Here, so-called net table is used for transmission information between schematic diagram and PCB, and the content that the net table comprises mainly contains the information of annexation between device and device.
Step 102 is called device from component inventory, calling module from the module library;
Concrete, when needs carry out new PCB design,, call designed PCB circuit required device and module according to the current PCB that will design, specifically how from component inventory, to call device, calling module belongs to prior art from the module library.Such as, at the invoked procedure of allegro software specifically: click " place " option in the allegro software, choosing derives device and the module of listing behind the net table, component inventory is used for depositing the device that needs in the PCB design, the module library is used for depositing the modular circuit file of generation, device and module all are codes in fact, and the form of code can just can be called device and module by the code that calls device and module by used eda software identification.
Step 103, device that utilization is called and the circuit among the modular design PCB;
Concrete, utilize the device that calls in the step 102 and the circuit among the modular design PCB, determine contour structures and the size of PCB; According to different purposes of design, the relation between the different circuit among the PCB is also different, so the interface relationship difference between each circuit, so determine interface device and the position of interface device on PCB of PCB according to this interface relationship; The electrical relation of the functional circuit that will realize according to PCB considers that definite PCB such as productibility, testability, reliability, radiating requirements go up the layout of device; Determine to realize the interconnected number of plies according to the complexity of electric connecting relation between the density calculation device of the contained device of PCB, finally realize the electrical interconnection of PCB;
Before the circuit in design PCB, for the standard design project, enhance productivity and improve the quality of product, adopt the prerequisite of standardized mentality of designing among the present invention as design PCB, has only the standardized mentality of designing of employing, could make and extract sub-design circuit, be the multiplexing accumulation that data are provided of later transplanting, finally play and constantly transplanted multiplexing effect as public module.
Step 104 after circuit design is finished, extracts the sub-design circuit in the designed circuit, the generation module circuit file;

The method of extracting sub-design circuit is: prepare an empty file earlier, derive the net table of the sub-design circuit that promptly will extract again from schematic diagram, the net table of the sub-design circuit that will extract is put in the empty file then; Handle the data of the source file that design circuit forms among the PCB, select in the source file and the corresponding data of sub-design circuit that promptly will extract, the data of being extracted are put into the empty file that carries the net table; After because the data extract of sub-design circuit come out, wherein most data meet multiplexing requirement, only exist low volume data not satisfy multiplexing requirement, device item etc. for example, so in order to make the data of extracting satisfy the multiplexing requirement of modular circuit file, also need data are carried out suitable modification, revise back generation module circuit file, the form of modular circuit file is can be by the form of use eda software identification.
Step 105 deposits the modular circuit file in module library as module, and wait is called;
Concrete, each modular circuit file can be regarded a module as, and waits in the module library as module stores and to call; In fact, the module library is the storage medium that can visit on a server that is used to deposit the generation module circuit file or the computing machine, for example C coils, D coils etc., as long as can have access to, storage can be finished down or under the catalogue of storage medium in the address that the modular circuit file is sent to server.
Further, based on technique scheme, when carrying out new PCB design, can utilize in the EDA design software function of module among the recognition principle figure automatically earlier, judge whether the module that new PCB design contains exists in the module library, if exist, just directly the module in the calling module storehouse generates circuit among the required PCB, if there is no, with regard to the processing procedure of execution in step 101～105.
For realizing said method, the present invention also provides a kind of system that realizes portable multiplexing of printed circuit board, Fig. 2 is the structural representation that the present invention realizes the system of portable multiplexing of printed circuit board, as shown in Figure 2, this system comprises: design module 21, extraction module 22, generation module 23, module library 24; Wherein,
