Breakfast Bytes: Dead Ends

Paul McLellan

Sometimes something comes along that looks like it is a portent of things to come, but then turns out to be a technological dead end. For example, in the 1990s, it seemed that you couldn't go to the mailbox or rent a video without getting an AOL...

Breakfast Bytes: Implementing Automotive Radar on Tensilica Processors

Paul McLellan

The big controversy about sensors in autonomous driving is whether lidar is essential. Radar has improved significantly in resolution and so I like to phrase the question as to whether radar is getting better faster than lidar is getting cheaper. Tod...

System, PCB, & Package Design : BoardSurfers: Going Beyond Just Correct - Improving and Optimizing Design and Routing

mrigashira

PCB layout editors provide many checks in the form of constraints and rules to ensure your design is correct. You even have the DFM rules to prevent fabrication or manufacturing issues. Then you have automatic routing to ensure an errorless board with the right connections and traces. But are you satisfied only with 'just a correct' board? Or, do you want to optimize it further? And what about 'quality'?

PCB、IC封装：设计与仿真分析: 专家访谈：多板PCB系统设计新思路

Sigrity

本文转载自Semiwiki.com。许多电子产品的创意都是从草图开始，然后在Visio或PowerPoint中绘制图表，最后再进入特定的EDA工具中进行设计。但是，这种方法使得纯图形工具绘制的图与EDA工具的设计之间存在很大的脱节，由于没有发生数据链接，所以在规范进行了更改后无法实现一致性和自动化。需求是前进的动力，Cadence® Allegro® System Capture工具可将对PCB系统级设计的需求转化为现实功能，不妨请 Cadence的Gary Hinde来为大家...
