之前高速先生谈的浅显易懂，事实理论较多，今天个人来点Allegro Pcb Design软件小技巧，出点奇招，正如孙子兵法所云：凡战者，以正合，以奇胜，让您在设计中将原本认为比较繁琐的操作变为简单一些，本操作是基于Candence Allegro平台，希望对正在使用或是准备 ...

上一章节谈的是placement功能的巧用，今天来谈另外2个，废话不多说，直接进入主题。 二 关于相对位移ix的使用 ix是allegro的相对位移指令，我们在进行平移或者相对位置移动时经常使用到，比如我们会在allegro的命令栏里按照下面格式输入： 关于这个格式，我 ...

在高速PCB设计中，BGA、QFN等高密度封装器件的breakout布线（又称neck-down区域）往往是信号完整性的薄弱环节。当走线从焊盘引出时，线宽骤变、参考平面不连续、空间受限等问题会引发显著的阻抗突变，导致信号反射、边沿畸变甚至误码率上升。如何在这一关键 ...

I’ve experienced a lot of pain with a recent project and wanted to share some thoughts: I was doing the PCB layout on a time-critical project and needed component footprints and 3D step models. Many ...
