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 ...

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 ...

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 ...

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.

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 ...

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 ...

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 — ...
