Allegro如何隐藏GND网络飞线

在进行PCB设计的时候，通常会隐藏掉GND网络的飞线，让PCB界面不会显得那么乱，有利于快速的走线。

（1）首先给GND网络分配一个颜色。

选择快捷菜单栏上的assign color（分配颜色）图标

然后在Options选项卡下选择一个暗一点的颜色

随便点击一个GND的网络

（2）然后选择Generaledit（一般编辑模式），选择网络

然后点击Edit菜单选择→Properties（属性），点击GND网络

跳出下面的对话框。找到No_Rat（无飞线）点击，选项就会跳到到右侧，然后点击应用，点击确认。即可。

回到PCB界面可以看到GND网络飞线已经隐藏

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.
