在进行PCB设计时，有时候会出现意外情况，如软件突然闪退或电脑死机等。导致一天设计的成果全部归零，这损失是巨大的。博主曾经受过深刻的教训。这时候设置软件的自动保存尤其重要。

点击Setup菜单→User Preferences...（用户参数设置）

在File_management下选择→Autosave

Autosave:是否开启自动保存，若需要开启，将其选中。这里选中。

autosave_dbcheck：自动保存前是否进行dbcheck，选中保存时间可能会长几秒。因为保存前要进行校验，可以不选。

autosave_name：设置自动保存的文件名，会在当前pcb目录下生成一个以该命名的文件。

autosave_time：设置自动保存的间隔时间，单位分钟。可设置10-300分钟。这里设置10分钟。

设置好各项参数后，点击确定即可。

Allegro provides a good and interactive working interface and powerful functions, and its front-end products Cadence, OrCAD, Capture, the combination of high-speed, high-density, multi-layer complex PCB design routing provides the most perfect solution.

Allegro has perfect Constraint Settings, users only need to set the wiring rules according to the requirements, and the design requirements of the wiring can be achieved without violating the DRC when routing, thus saving the tedious manual inspection time and improving the work efficiency!

It can also define parameters such as minimum wire-width or wire-length to meet the needs of today's high-speed circuit board wiring.

Constraint Manger provides a simple interface for users to set and view Constraint declarations.

Its combination with Capture allows E.E. electronics engineers to set up regular data when drawing a circuit diagram and bring it with them to the Allegro working environment, where it can be automatically processed and checked when placing parts and wiring. The empirical values of these regular data can be reused for the same nature of the circuit board design.

In addition to the above functions, Allegro's powerful automatic push and stick line and perfect automatic repair line function provide users with great convenience;

The powerful mapping function can provide multiple users to deal with a complex board at the same time, thus greatly improving the work efficiency.

Or use the optional graph cutting function to cut the circuit board into various blocks, so that each block has a full-time person at the same time to design, to achieve the purpose of the same graph design and can shorten the time course.

After renaming, online interchange and modifying logic during routing, users can easily return to Capture wiring diagram, and update the wiring diagram to Allegro after modification.

Users can also click and modify objects between Capture and Allegro.
