PCB、IC封装：设计与仿真分析: Ken的博客系列之七 | 千兆位串行链路接口的SI方法

Sigrity

作者：Ken Willis 上一篇：使用IBIS-AMI模型进行仿真反向信道训练均衡器自适应的另一项能力是反馈训练。许多高速串行协议规定SerDes接收器可以评估发射器送出的training patterns的信号质量，以此来决定发射器均衡的大小，然后将这个要求反馈给发射器，然后评估下一个training pattern。这个过程会重复多次，直到接收器对发射器的设置满意，那么这个满意的设置就会被实际传输出去。图1：反向信道训练（点击查看大图）尽管目前的IBIS标准还不支持反馈训练功能，...

Breakfast Bytes: Programming Languages for Embedded Systems

Paul McLellan

How do you program an embedded system? Say, the code that runs on the control processor on a big SoC? What programming language should you use? I have never really programmed an embedded system, unless you count writing a couple of experimental progr...

System, PCB, & Package Design : BoardSurfers: PCB Electronics - Defining and Applying Physical and Spacing Constraints

mrigashira

If you get frequent calls from your fab houses or your customers regarding your product, or if your schematic, layout, and packaging engineers spend a lot of time exchanging notes about their requirements not being met, resulting in back and forth of designs, or if you believe, like most of us do, that a product should do what it was designed to do, constraints are your friends.

Digital Design: Upcoming Webinar: AI Accelerator Design with Stratus HLS

dpursley

There is no doubt that 2019 has seen an explosion of artificial intelligence/machine learning usage for Stratus HLS. In fact, this momentum started in 2017.

Noting the increase in machine learning applications in our user base, we researched how to efficiently move from a TensorFlow model to hardware via Stratus HLS. By July 2018, AI startup Syntiant was talking at DAC about how they went from spec to tapeout in six …

System, PCB, & Package Design : IC Packagers: Capture Your Design for Review

Tyler

How do you quickly show another developer an issue that concerns you? Do you need to send them the entire design, start a screen sharing session, or bring up the Symphony server and allow them to connect? All of these are GREAT review mechanisms; however, they aren’t always viable or convenient.

System, PCB, & Package Design : DATA Pulse: Track Your Components—Efficient Library and Design Data Management

Auromala

Ever noticed how some objects always mysteriously disappear? It's like they have their own legs. Or maybe, secretly, they thirst for adventure and go wandering off. Socks for example. Why does one twin always disappear after a round in the washing machine? After a few months, you just have a sad pile of lonely, orphaned socks in a variety of colors. Pens are equally guilty. They're always disappearing. Pen caps are even…

PCB、IC封装：设计与仿真分析: Ken的博客系列之六 | 千兆位串行链路接口的SI方法

作者：Ken Willis 上一篇：高效的互连提取使用IBIS-AMI模型进行仿真此时，SerDes元器件供应商应该已经提供了所需的IBIS-AMI模型，如果这些模型可用，那么替换仿真测试平台中的对应模型。现在，我们重点关注后仿真的验证工作。在仿真测试平台中替换为你自己的模型，尽管这时看起来你好像就马上可以进行仿真工作了，但是对于IBIS-AMI模型仍然有许多工作需要做。如前所述，算法部分或者IBIS-AMI模型的“AMI”部分为SerDes的均衡功能。在双沿数据速...

System, PCB, & Package Design : BoardSurfers: PCB Electronics - Electrical Constraints

mrigashira

Whether it's NASA's space missions or a school camping trip; building a cutting-edge, reusable rocket system or baking a simple lemon tart - planning is a must to avoid disasters, or at least to get a predictable output. So is the case with PCBs. You want to plan ahead to avoid design mistakes that can cost you money and time. And that's where constraints come handy.
