Abstract

A computer aided design system comprises a dividing module, a storage, an interface creating module, a selecting module, and a display module. The dividing module divides the names into groups according to a predetermined rule. The group comprises a plurality of the targets set on the different layers. The storage records the relationship between the groups and the targets. The interface creating module creates a user interface base on the groups and selects at least one group in the same user interface from the operation of the user. The selecting module selects targets according to the selected groups. The display module displays the selected targets.

Claims

1. A computer aided design system of a device used in the printed circuit board layout system for selecting targets on different layers of a PCB layout design, the device comprising at least one hardware processor and a storage;

and the computer aided design system comprising one or more programs, the one or more programs stored in the storage, executable by the at least one processor, the one or more programs comprising;

a dividing module adapted to divide the targets into groups according to a predetermined rule, each group comprises a plurality of targets set on the different layers;

an interface creating module adapted to create a user interface based on the groups and select at least one group according to a user'"'"'s operation on the same user interface;

a selecting module adapted to select the targets corresponding to the selected at least one group; and

a display module adapted to display the selected targets simultaneously.

2. The computer aided design system of claim 1, wherein the computer aided design system further comprises an obtaining module adapted to obtain some feature of the targets.

3. The computer aided design system of claim 2, wherein the dividing module further comprises a first dividing unit and a second dividing unit, the first dividing unit is used for dividing the targets into different first level groups according to a first predetermined rule, and the second dividing unit is used for dividing each first level group into different second level groups according to a second predetermined rule.

4. The computer aided design system of claim 3, wherein the first predetermined rule is having the targets with one common feature divided into a first level group.

6. The computer aided design system of claim 1, wherein the selected targets are highlighted displayed on a screen of the device.

7. The computer aided design system of claim 1, wherein the computer aided system further comprises an extracting module for extracting the selected targets from the storage according to the selected groups and sending the selected targets to the display module.

8. The computer aided design system of claim 1, wherein the user interface comprises an all on button, an all off button, a reset button, and a selecting area.

9. The computer aided design system of claim 8, wherein the selecting area comprises the group labels, the group'"'"'s labels are arranged in column in the selecting area.

10. The computer aided design system of claim 8, wherein the selecting area further comprises group'"'"'s names and checkboxes, the group'"'"'s name are arranged in rows in the corresponding group label column and a checkboxes is set in front of each group'"'"'s name.

5. The computer aided design system of claim 5, wherein the second predetermined rule is having the targets in each first level group divided into different second level groups with one common feature of or combination of more than one common features of the targets except the common feature adopted by the first predetermined rule.

11. A selecting method for selecting targets on different layers of a PCB layout design in a computer aided design system, the method comprising:

dividing the targets into groups according to a predetermined rule, each group comprises a plurality of targets set on the different layers;

creating a user interface based on the groups and selecting at least one group in the same user interface;

selecting the targets corresponding to the selected at least one group; and

displaying the selected targets simultaneously.

12. The method according to claim 11, wherein before the step of dividing the targets into groups according to a predetermined rule further comprising:

obtaining some features of targets on a PCB layout design.

13. The method according to claim 12, wherein the step of dividing the targets into groups according to a predetermined rule further comprising:

dividing the targets into different first level groups according to a first predetermined rule; and

dividing each first level group into different second level groups according to a second predetermined rule.

14. The method according to claim 13, wherein the first predetermined rule is having the targets with one common feature divided into a first level group.

15. The method according to claim 14, wherein the first predetermined rule is having the targets in each first level group divided into different second level groups with one common feature of or combination of more than one common features of the targets except the common feature adopted by the first predetermined rule.

16. The method according to claim 13, wherein if one first level group is selected, second level groups corresponding to the selected first level groups are also selected.

17. The method according to claim 11, wherein further comprising a step of extracting the selected targets from a storage.

18. The method according to claim 11, wherein the user interface comprises an all on button, an all off button, a reset button, and a selecting area.

19. The method according to claim 18, wherein the selecting area comprises the group labels, group'"'"'s names, and checkboxes;

the group'"'"'s labels are arranged in column in the selecting area, the group'"'"'s name are arranged in rows below the corresponding group label and a checkboxes is set in front of each group'"'"'s name.

20. The method according to claim 11, wherein the selected targets are highlighted displayed on a screen of the device.
