Create Once and Test Everywhere: The Promise of Portable Stimulus
The problem was straightforward: Different test platforms were used by different engineering professionals throughout the verification phases of simulation, emulation, prototyping and other types of testing. In the semiconductor chip world, verification refers to the process in which a design is tested (or verified) against a given design specification before tape-out, i.e., before the design is made into a silicon chip.
Two Myths About Silicon Photonic Chips
The coming of silicon photonic technology in the datacom and telecom industries has been foretold for the last several decades. Indeed, replacing copper wires with fiber optics and silicon photonic interfaces has been occurring in these markets, just at a slower pace than predicted. Chris Cole, VP of Advanced Development at II-VI, challenges the expectation of a wide-spread replacement of copper wires with silicon photonic interfaces.
Fundamentals of Signal Integrity
As the name suggests, signal integrity deals with the integrity of an electrical signal. It all stems from the fact that digital signals are not really binary values of “1” or “0” but are analog voltage (or current) waveforms. As such, these waveforms are subject to the real-world, physical effects of noise, distortion, and loss. If the distances are short and at low bit rates, then a simple conductor will transmit a waveform with acceptable fidelity.
Top 10 2019 engineering, science, and technology awards
“The Royal Swedish Academy of Science Nobel Prize in Physics recognizes both theoretical and experimental contributions to understanding the universe. This year, the prize is awarded to APS Fellow James Peebles (Princeton University), Michel Mayor (University of Geneva), and Didier Queloz (University of Geneva; University of Cambridge).
Save Your Crash Test Dummy
The finite element (FE) method, the Internet of Things (IoT), machine learning, digital twins. A lot of fancy technical buzzwords that, when applied to the manufacturing process, all seek to capture the same ancient idea: Measure twice, cut once. Simulation and testing processes of one form or another have long been critical to manufacturing.
5 Tips for Versioning Embedded Systems
One topic that can be tricky for embedded systems engineers is how to version their embedded system. Every embedded system has two primary systems that need to be versioned, the hardware and the software. While versioning the system sounds simple, it can be confusing on the best way to version the system. In this post, we will examine five tips for versioning your embedded system. While versioning the system sounds simple, it can be confusing finding the best way to version the system.
Simulation in Autonomous Driving - Why Societal Change Is as Necessary as Technical Innovation
NOTE: THIS ARTICLE IS AWAITING A SIGNED CONTRIBUTOR AGREEMENT A decade ago, the concept of a fully driverless vehicle remained largely the preserve of academic research institutes. Now, commercial activities, such as Waymo’s operations in Phoenix, have shown that not only are driverless vehicles commercially possible, they have the potential to completely alter our socio-economic perception of personal transportation.
How to Become a Bug Squashing Connoisseur
I’ve said it before and I’ll say it a million more times, I hate debugging. It’s not that I don’t enjoy a good problem-solving exercise. After all, I am an engineer. The problem that I have with debugging is that it’s the wrong problem to be solving! Instead of adding new features, differentiating the product, or doing other productive work, I’m stuck toiling away trying to discover what I overlooked.
Call for Proposals Open for ARM TechCon 2017
The Technical Program Committee for ARM TechCon 2017 is now accepting technical session proposals for the conference, which will take place October, 24-26, in Santa Clara, CA. Designers, engineers, and developers are encouraged to submit their proposals for technical presentations or panels for the three-day event.
How to Make Sense Of the IEEE Std 802.3bj-2014 Alphabet Soup
The industry appears to be transitioning from 10x10G to a more efficient 4X25G. The first standard for 25Gb/s signaling was the OIF-CEI with VSR, SR and LR standards. What I have been looking at recently are the Ethernet 802.3bm 100GBASE-KR4 backplane standard and the Ethernet interconnect standard 802.3bj. To achieve 100G there is CAUI10, which is 10 lanes of 10G = 100G, while CAUI4 is 4 lanes of 25G = 100G. 100GBASE-CR4 is 4 lanes of 25G using CAUI4 = 100G throughput.
DesignCon Cartoon Caption Contest
Looks like this energetic engineer has impressed his coworkers, Chiphead included, with his amazing manual dexterity. The only thing this cartoon is lacking is a cleverly crafted caption – and for that we’re turning to you. Complete this cartoon with the perfect caption to explain what’s happening in this lab today – and hopefully give us all a good laugh in the process. Submit your bit of witty wisdom in the comments field below.
