First embodiment
Fig. 2 is refer to, a kind of actual components it illustrates one embodiment of the invention offer are in schematic diagram component library
Schematic diagram element method for designing and PCB encapsulation storehouse in component encapsulation method for designing flow chart.The design side
Method, it may include following steps 201-205：
Step 201, according to its schematic diagram element in schematic diagram component library of actual components structure design, while setting up former
Manage opening direction, the Pin locations information of the interface of schematic diagram element of the interface of pel part, and the element that will be designed
Storage is in schematic diagram component library.
Can according to the structure of actual components design principle pel part.The Pin locations information of the interface of schematic diagram element
Numbering, pin the putting in order on the interface of schematic diagram element of each numbering of pin can be included.
Preferably, in actual applications, the attribute information of schematic diagram element, attribute can be set up in schematic diagram component library
Information is including the opening direction of the interface of schematic diagram element, the Pin locations information of the interface of schematic diagram element etc..May be used also
Think the pin design attributes of schematic diagram element interface, will each pin name be set to variable name, the category of variable name and pin
Property is corresponding.
The pin attribute of the interface of schematic diagram element can include numbering, the pin of pin on the interface of schematic diagram element
Put in order.So when principle diagram design is carried out, the pin attribute information of interface that can first according to actual components and
The opening direction of interface calls out the corresponding schematic diagram element of the actual components from schematic diagram component library, further according to institute
Pin function defined in the actual components to be designed, directly changes the pin attribute of the interface of the schematic diagram element for recalling, and
The attribute of the pin of the interface of the schematic diagram element stored originally in schematic diagram component library will not be changed, it is ensured that schematic diagram element
The pin attribute of the interface of the schematic diagram element stored originally in storehouse will not be changed, and so can further accelerate design
Efficiency.
Step 203, according to its component encapsulation in PCB encapsulation storehouse of actual components structure design, while setting up element envelope
The opening direction of the interface of dress, the Pin locations information of the interface of component encapsulation, and the component encapsulation storage that will be designed
In PCB encapsulation storehouse, the component encapsulation in PCB encapsulation storehouse is corresponding with the schematic diagram element in schematic diagram component library.
The component encapsulation in storehouse can be encapsulated according to the structure design PCB of actual components.The element set up in PCB encapsulation storehouse
The underlying attribute of encapsulation, including component encapsulation interface opening direction, the Pin locations information of the interface of component encapsulation
Deng.The Pin locations information of the interface of component encapsulation can include the numbering of pin, the pin of each numbering in component encapsulation
Putting in order on interface, during actual design, the pin number of the interface of the actual components of same model is often fixed
, therefore define only the position of the first pin, then putting in order for all pins just can determine that.
Because in the schematic diagram element being directed in the schematic diagram component library of same actual components design and PCB encapsulation storehouse
Component encapsulation, so schematic diagram element in all information and the schematic diagram component library of component encapsulation in PCB encapsulation storehouse
All information are corresponding.The opening direction of the interface of the schematic diagram element i.e. in schematic diagram component library is encapsulated in storehouse with PCB
Component encapsulation interface opening direction it is consistent, the pin of the interface of the schematic diagram element in schematic diagram component library
Sequentially, numbering and positional information etc. encapsulate order, numbering and the positional information of the pin of the interface of the component encapsulation in storehouse with PCB
Etc. consistent.Ought define the interface of schematic diagram element in schematic diagram component library opening direction and pin it is suitable
Sequence, then PCB encapsulation storehouse in component encapsulation interface opening direction and pin order also just secure.So from principle
The order in the direction and pin for the component encapsulation of PCB G- Designs just can be intuitively found out in figure.
Relative to existing PCB design method, the present invention in schematic diagram component library by increasing connecing for schematic diagram element
Mouthful the design of opening direction and pin order design etc., to determine checking in the PCB encapsulation storehouse interface of component encapsulation
Direction and pin order, it is to avoid because component encapsulation checks direction with principle pel part in schematic diagram component library in PCB encapsulation storehouse
Check that direction is different, cause the unascertainable problem of pin order.Schematic diagram element connects i.e. defined in schematic diagram component library
First pin of mouth corresponds to the position of the first pin of the interface of component encapsulation in PCB encapsulation storehouse, then coordinates schematic diagram element
Opening direction with the interface of component encapsulation is defined, you can to determine in PCB G- Designs element in PCB encapsulation storehouse completely
The pin order of encapsulation, PCB figures and the schematic diagram of so design are unique corresponding, because the interface of same actual components exists
Checking the position of its first pin has two kinds, so will design two groups of schematic diagram elements and unit for the actual components of same model
Part encapsulation is respectively stored in corresponding schematic diagram component library and PCB encapsulation storehouse, in the design so after, because PCB is sealed
Component encapsulation in dress storehouse is unique corresponding with the schematic diagram element in schematic diagram component library, therefore PCB figures will not be produced to set
The problem that meter is not inconsistent with principle diagram design.
It is illustrated by taking Fig. 3 and Fig. 4 as an example, Fig. 3 (A) show a kind of actual components such as interface element in the present invention
（The for example, interface element of liquid crystal display drive circuit plate）A kind of schematic diagram element in schematic diagram component library signal
Figure, Fig. 3 (B) is the component encapsulation in corresponding PCB encapsulation storehouse unique with the schematic diagram element shown in Fig. 3 (A), shown in Fig. 4 (A)
It is another schematic diagram element schematic in schematic diagram component library of the interface element in the present invention, principle shown in Fig. 4 (A)
The Pin locations and Fig. 3 of pel part（A）The Pin locations of shown schematic diagram element are different, and Fig. 4 (B) is and principle shown in Fig. 4 (A)
Component encapsulation in the unique corresponding PCB encapsulation storehouse of pel part.
As shown in Figure 3 and Figure 4, the schematic diagram element of one embodiment of the present invention is unique corresponding two groups with component encapsulation
Design, position different instructions are defined according to pin, and Fig. 3 (A) and Fig. 3 (B) is one group, and Fig. 4 (A) and Fig. 4 (B) is one group, principle
The interface opening direction of pel part is consistent with the opening direction of the interface of actual interface element, in schematic diagram component library
The Pin locations of the schematic diagram element correspond to the Pin locations of the component encapsulation in PCB encapsulation storehouse.Schematic diagram element in Fig. 4
And the pin of component encapsulation put in order it is opposite with putting in order for the schematic diagram element in Fig. 3 and the pin of component encapsulation.
Schematic diagram element in Fig. 3 has the schematic diagram element in pin arrangements order sign 213,215, Fig. 4 with component encapsulation respectively
With in component encapsulation respectively have pin arrangements order sign 223,225, designer by pin the mark 213 that puts in order,
215 or 223,225 can just uniquely determine in schematic diagram component library in the element and PCB encapsulation storehouse pin in the component encapsulation
Put in order.
For example, first group of design is as shown in figure 3, Fig. 3（A）The interface of the schematic diagram element set up in schematic diagram component library
Be open 210 directions and Fig. 3（B）The direction phase one of opening 212 of the interface of the component encapsulation set up in PCB encapsulation storehouse
Cause, the Pin locations information of the schematic diagram element set up in the schematic diagram component library equally also with set up in PCB encapsulation storehouse
The Pin locations information of component encapsulation is consistent, i.e. 10 pins of the schematic diagram element in schematic diagram component library（Respectively
One pin 1, second pin 2, the 3rd pin 3 ..., the tenth pin 10）Put in order with PCB encapsulation storehouse in component encapsulation 10
Individual pin（Respectively the first pin 1a, second pin 2a, the 3rd pin 3a ..., the tenth pin 10a）The phase one that puts in order
Cause, what the position of the first pin 1 of the schematic diagram element in schematic diagram component library encapsulated the component encapsulation in storehouse with PCB first draws
The position of pin 1a is corresponding, and the position of other pins also mutually corresponds to.So as to put in order mark 213 and 215 just by pin
The arrangement that the pin of component encapsulation in schematic diagram element in schematic diagram component library and PCB encapsulation storehouse can be uniquely determined is suitable
Sequence；
Second group of design is as shown in figure 4, Fig. 4（A）The direction of interface opening 220 of the element set up in schematic diagram component library
Direction and Fig. 3（B）The direction of interface opening 222 of the component encapsulation set up in PCB encapsulation storehouse is consistent, in principle pel
In part storehouse set up schematic diagram element Pin locations information equally also with PCB encapsulation storehouse in set up component encapsulation pin
Positional information is consistent, i.e. 10 pins of the schematic diagram element in schematic diagram component library（Respectively the first pin 1A, second are drawn
Pin 2A, the 3rd pin 3A ..., the tenth pin 10A）Put in order with PCB encapsulation storehouse in component encapsulation 10 pins（Respectively
It is the first pin 1b, second pin 2b, the 3rd pin 3b ..., the tenth pin 10b）Consistent, the i.e. principle pel that puts in order
The position of the first pin 1A of the element in part storehouse is relative with the position of the first pin 1b of the component encapsulation in PCB encapsulation storehouse
Should, the position of other pins also mutually corresponds to, so that, original can just be uniquely determined by the mark 223 and 225 that puts in order of pin
Schematic diagram element and PCB in reason figure component library encapsulate putting in order for the pin of the component encapsulation in storehouse.
However, the present invention is not limited to above-mentioned interface element, it is suitable for pin function and pin order are use
The customized actual components in family, for representing the figure of the opening direction of schematic diagram element or component encapsulation in the present invention
210th, 212,220 and 222, or other can represent schematic diagram element or component encapsulation confirmation direction significant figure
Shape；Be used to representing in the present invention each schematic diagram element or component encapsulation pin check order symbol 213,215,223 and
225, or the other shapes of pin for representing schematic diagram element or component encapsulation check the symbol of order；The present invention will be same
One actual components are designed to two groups of mutual corresponding schematic diagram elements and component encapsulation according to pin definition, it is also possible to according to possible
Pin order design multigroup mutually corresponding schematic diagram element and component encapsulation and be respectively stored in schematic diagram component library and PCB
In encapsulation storehouse.
Step 205, the corresponding relation storage of the schematic diagram element that will be designed and component encapsulation in schematic diagram component library and
For being called when Design PCB is designed in PCB encapsulation storehouse.
