1. After Allegro automatic wiring, adjust the right angle to 45 degrees: route gloss parameters convert corner to arc.

2. The menu font of Allegro system is too small. Modify: in the setup user preferences editor UI fonts font, change the value a little larger, and the default value 12 is changed to 14.

3. Hide copper cladding: setup user preferences editor display shape_ fill-no_ shape_ Fill.

Dynamic filling mode: smooth, rough and disable, smooth fully displays the avoidance effect, rough: the avoidance effect of copper is not completely displayed, disabled: the avoidance effect of copper is not displayed. The latter two methods can be used first when copper coating, which can speed up the speed of wiring and DRC inspection, but when it comes to artwork, it can be converted by update to smooth. Clearance thru pin oversize value of dynamic copper sheet plus other defaults.

Summary of using skills of cadence Allegro 16.5

Merge the two copper sheets: shape merge shapes, and then click the two copper sheets separately.

4. Add test points: set by manufacturing testprep automatic.

5. After the completion of Allegro wiring, there are three modes to modify and adjust route slide.

6. Undo the component that has been placed, and right-click unplace component.

7. When placing components, it is necessary to turn off the fly line for convenience: display – blank rates – all.

8. Find a component, find dialog box – find by name symbol (or pin) – name, enter component name, enter

9. Constraint rule setting: set up constraints constraint manager.

10. Change the right angle of the border to a rounded corner (the graphic box drawn by line): Manufacture drafting filler. Enter the appropriate radius value in options radius, and click two straight lines to convert them into fillets.

11. Display the real-time routing length: setup user preferences route connect allegro_ etch_ length_ on。

12. Allegro set the number of PCB layers: setup — cross section. Add the layers you need.

13. Setup cross section negative artwork.

14. Switch shortcut key of Allegro layer: switch between -, + on keyboard.

15. Modify pad number: first set display: display color / visibility package geometry pin_ Number, then edit text, click the corresponding pin (turn red) to input, and click in the blank space.

16. Lock / unlock components in Allegro: click components or select multiple components in the box, right-click fix and unfix.

17. Modify the existing border line: Method 1: edit delete, then select the line to edit, right-click cut, edit edit vertex, and move the line endpoint to fit. Method 2: edit delete, select lines in find panel, double-click to delete, and draw border line again according to requirements.

18. To protect manual wiring from being covered by automatic wiring, in addition to fix components, there is another method: Route – “automatic router sections all but selected. In object type nets, select the network to be protected to the selected object.

19. Allegro automatic routing is generally right angle, with 45 degree routing setting: route route automatic router setup enable diagonal routing, the values of wire grid and via grid can be modified.

20. Generate drilling file: first set the parameter manufacturing NC NC parameters, and then manufacture NC drill to produce circular drilling. If there are holes with other shapes such as square, you need to run NC route separately, and then dill legend is placed on the drawing.

21. Component library in installation path_ The encapsulation library is in the installation path of SPB_ 16.5\share\pcb\pcb_ Libsymbols.

22. After the screen printing is generated, the font size of the screen printing with two layers of screen printing display needs to be adjusted. Select text in the edit text and find panel to adjust the font size as a whole. Select manufacturing in the option panel class. In particular, if you do not select subclass, fill in the line width and select the size in the text block. On the other hand, adjust the two layers of silk screen separately. First adjust the top layer of silk screen, you must turn off color manufacturing autosilk_ Bottom, right click done on the box selection board, and adjust the bottom layer. The same is true for silk screen printing.

23. The light drawing files of plate making include: all layer files. Art files, drilling files. DRL, square and other shape drilling files (if any). Rou, light drawing parameter files. Art_ Param.txt, drilling parameter file NC_ param.txt 。 In particular, for the convenience of next light drawing, the configuration file of light drawing layer can be generated, which can be called directly next time, and the parameters will be set automatically.

Manufacture artwork film control select all, then right-click the folder icon of one of the photo files, and select save all checked to generate the configuration file film in the current path_ Setup.txt file. Just call replace next time.
