Whiteboard Wednesdays: Whiteboard Wednesdays - An Intuitive Introduction to Finite Element Analysis (FEA) for Electrical Engineers, Part 1

References4U

In this week's Whiteboard Wednesdays video, Tom Hackett begins a 2-part introduction to finite element analysis (FEA) by looking at a simple model of a bridge and showing why FEA techniques are required for analysis of real-world structures. For a detailed explanation of the mathematics behind Finite Element Analysis, see this excellent video by Grasp Engineering: Practical Introduction and Basics of Finite Element…

Breakfast Bytes: Running the Software for an Embedded System

Paul McLellan

A big challenge with developing a modern SoC is developing the software. Not so much the development itself, which is not very different from any other software development, but running and debugging the software. Waiting for the silicon to...

System, PCB, & Package Design : IC Packagers: Finding Design Issues in SiP - Three Options for DRC Management During Sign Off

Tyler

Your design is complete. Yet, you have 20 DRC violations that need to be addressed (whether that means correcting the constraint required value, modifying objects, or waiving the DRC to sign off on it as okay). What’s the best way to go about r...

Analog/Custom Design: Virtuosity: Automated Device Placement and Routing—Base Layer Fill Insertion

Sravasti

Welcome back to my next post in the Virtuoso Automated Device Placement and Routing blog series. At advanced node, after running the placer, there are a few additional requirements for base layers to be taken care of before the layout is routed and taken to completion. In this blog post, I’ll talk about how adding device fills helps meet these requirements. Read the post to know more.

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，...

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…
