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 ...

Pulsonix-TRM interface bridges gap between PCB layout and thermal analysis, enabling engineers to identify and address ...

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 ...

From the circuit diagram developed, it is possible to perform simulations and design the PCB by exporting Gerber/drill files. No matter what the design, engineers need to know precisely how the ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced the Cadence ® Allegro ® X AI technology, a next-generation system design technology that offers ...

There are certain design guidelines for PCBs that don’t make a lot of sense, and practices that seem excessive and unnecessary. Often these are motivated by the black magic that is RF transmission.

Thermal analysis is the process of measuring how a material/device behaves at different temperatures. For many applications, especially single materials, a thermal analysis is a physical analytical ...

Siemens Mentor group now offers a free version of its HyperLynx design-rule-checking software for checking printed circuit boards using the latest high-speed serial interfaces. Mentor, a Siemens ...

Every switch-mode power supply presents a wide-band noise source. Integrating a DC/DC converter from the car board net into an automotive control unit and still fulfilling the EMC requirements of ...

Protel Autotrax is a PCB design tool first released for DOS in the mid-80s. Consider this a look at the history of PCB design software. I’m not recommending anyone actually use Protel Autotrax — ...
