Description
Technical field
The present invention relates to the Printed Circuit Board Design technology, relates in particular to based on network printed circuit board concurrent design system and method thereof.
Background technology
Printed circuit board (Printed Circuit Board, PCB; Also claim printed circuit board (PCB)) be a kind of on insulating substrate, form the printed board of the conductive pattern of printing device or printed wiring and both combinations by predetermined design.It is a kind of physics realization form of circuit design in the hardware designs.Present hardware design technique, (Electronic Design Automatic, EDA) software carries out computer-aided design to most employing electric design automations.Typical hardware design technique is used the principle diagram design instrument earlier usually, designs schematic diagram, by the PCB design tool, designs corresponding printed board line map again, and promptly the PCB file is processed, and obtains circuit board.
In the Printed Circuit Board Design field, more and more general to the application that high plate thickness, the high number of plies, high connection network are counted PCB.The design efficiency of printed circuit board is very high now, and smaller the space that efficient improves once more, this just exists the problem that how to reduce the design time bottleneck.
For a long time, Printed Circuit Board Design all is to adopt the method for special messenger's design, and promptly a people begins to finish alone the placement of device, the connection of network etc. from receiving task.This method for designing has its advantage: under the situation of low connection network number, the designer is very familiar to veneer, and is responsible fully to the design of veneer.But shortcoming is arranged also: in the high linking number network printed circuit board of design, veneer that surpasses 20,000 network linking numbers for example, the time that designer finishes designing institute to be needed is surprising.
Therefore we as can be seen, the PCB design be hardware designs must be a very important ring in the product development through the path.And since on to meet the needs of production and processing down in the face of the demand of principle design, also be a very complicated ring therefore, need in product development, spend the more time.For example the new design pcb board of the pin about 1 6000 may need 20-30 working day for a skilled PCB Designer.If PCB is more complicated, then required time is just more.Therefore,, accelerate the launch schedule, carry out a PCB design (Parallel PC B design just) simultaneously, just become inevitable choice by two people or more people in order to reduce the PCB design time.
But because the particularity of PCB design, it must all be included in the encapsulation of circuit board, layout, wiring etc. in same the PCB figure, that is to say that the drawing number of design is unique.All designers must design at same PCB figure.This has brought difficulty just for Parallel PC B design.Existing EDA design software almost is difficult to perfectly carry out Parallel PC B design.
At a circuit board, at present the common design mode of industry all is to be designed separately by a designer, comprise from schematic diagram net table call in the printed circuit board layout and network connects, all follow the prescribed order serial design step by step.
In this serial design, designer's layout still connects up and all needs to carry out with following the prescribed order.In layout, need or connect a zone according to the zone and carry out layout (perhaps a module connects a module) according to zone of functional module, the time used aspect layout is longer.In wiring, also be like this equally.For example, when adjusting cabling, designer must one deck connects one deck or a zone and connects one and adjust optimization regionally, and it is very long to expend time in.
Also have a kind of method for designing to be, method is by turns adopted in two above designer's serials designs, avoids that designer is overworked to cause error, and can design incessantly, reduces design time.
The shortcoming of this method for designing is, all designers that participate in design must understand circuit theory diagrams or schematic diagram very much, when carrying out work handover, must be with the key work of oneself and the design done people's explain oneself to handing-over, otherwise be easy to make mistakes.Aspect this, wasted the plenty of time.
The main feature of existing P CB concurrent designing technology is that the designer passes through the division of labor, independently carries out part design respectively.The design of the two is relatively independent, that is to say that the designer designs on computer independent of each other usually, carries out file then interimly and merges.In existing concurrent designing technology, when layout, strictness is divided into several sections, carries out layout designs then separately, and in this division of labor design process, designer A can't see another designer B what is being done, and just can see after can only merging.Can only be after designer A design is finished, generate a special interface document, on the file of designer B, call in this interface document then, if also there is a designer C, just must merge the merging interface document that designer A and B generate earlier, then, on the file of designer C, call in this and merge interface document, by that analogy, the designer is many more, and it is just complicated more to operate, except complicated operation, therefore the problem that also exists a lot of data to merge with interface document can produce the duplication of labour.
The shortcoming of this technology is:
1, must be divided into two or more relatively independent circuit units to a PCB figure, each designer is responsible for a part, merges then.But, be divided into a plurality of independent parts and be not easy in fact owing to be same circuit board; Particularly wiring must separate, otherwise can't merge, but in fact be exactly that wires design almost can't be divided into fully independently unit;
Even 2 branches have been got well independently unit, but each independently has holding wire to connect usually between the circuit of unit, and these holding wires all can only be to be combined after, finish (can not walk abreast this time) separately by certain designer, therefore can not in whole PCB design process, carry out concurrent designing;
3, in the PCB design software interface of a designer, can't see another designer's action immediately at oneself.Therefore just inevitably may produce misunderstanding and the design conflicts that causes owing to instant confusing communication between two designers, thereby cause doing over again;
4, existing this method need be extracted the information of topology file, cloth line file, silk-screen, shop copper etc. respectively from design document, import another designer's design document then respectively, finishes merging.But in fact there are a lot of information can not support the method for extracting, importing fully in the PCB design document.For example power supply, The Split Ground Plane and shop copper just can't be derived fully, be imported.After shop copper is derived, all can lose network attribute; And
5, simultaneously, the information of extracting layout, wiring, silk-screen, shop copper respectively imports again, is the work of the extra generation of existing concurrent designing technology institute, need spend more the regular hour.Adopting the concurrent designing absolute time is to have reduced, but owing to produced extra work, what spent is total manually than design is in fact also more separately.
Therefore, exist the system of the concurrent designing that realizes printed circuit board and the demand of method thereof.
