In my previous article ( From AMBA ACE to CHI, Why Move for Coherency? ) I talked about how coherency needs have evolved from AMBA ACE to the highly successful and widely adopted CHI architecture. Since the introduction of CHI, Arm has continually refined the specifications with clarifications, improvements...

Here are a few teasers for what you'll find in this week's round-up of CFD news and notes. How AI can be trained to identify more objects than are in its learning dataset. Will GPUs really take over and disrupt CFD simulation? A beginner&#39...

We are very excited to be part of a team selected for a Dept. of Energy INCITE Award. The Innovative and Novel Computational Impact on Theory and Experiment program is how the DoE's Office of Science provides the scientific community access ...

The big news about PCIe 6.0 is that the specification has been released by the PCI-SIG. I covered some of PCIe 6.0 in my post The History of PCIe: Getting to Version 6 , although a lot of that post was about earlier versions of the standard. More rece...

2021 was famous for some of the worst security issues (accompanied by obligatory picture of bad guy in a black hoodie): The very first blog post of the year covered SolarWinds. See my post The Biggest Security Breach Ever . The middle of the year saw...

Pipistrel used the propeller as an airborne wind turbine, by transforming the energy created by the descent of an aircraft into electric energy and storing it in a battery. As a result the aircraft consumes 6% less energy during climb. and net energy consumption during ascent/descent manoeuvres decreased...

There are a lot of commonalities between computational fluid dynamics (CFD), software, and chip design. All of them create a specification of the object of interest, and eventually use that representation as part of the manufacturing process. In betw...

Today’s interview features Dajana Danilovic, an application engineer based near Munich, Germany. In this video, Dajana shares about her pathway to becoming an engineer, as well as the importance of great teamwork and good communication. She has...

FINE/Marine の最新バージョンでは、耐航性計算の高速化、抵抗計算の粗メッシュ初期化、Rhinoプラグインによるジオメトリ準備の高速化、解適合格子の改善などが行われています。 C-Wizardに2つの画期的な機能が追加されました。 耐航性計算の高速化：クラスター環境などがないユーザー様でも、現実的な計算時間で耐航性計算ができるようになりました。非定常シミュレーションは、実質的に精度を落とすことなく、半日で終了します。ぜひお試しください。 抵抗計算のための粗いメッシュの初期化：ワンク...

Welcome, CFDers, to a new year of CFD news, applications, software, events, and general fluid dynamics fun. To pay the bills before jumping into this week's topics, there are two Cadence CFD events coming up that you really should register for. ...

Monday is Martin Luther King Jr. Day. Breakfast Bytes will not appear and so today, the last post before the holiday, I go offtopic. Not too far off-topic, since this affects blogging as well as being amusing. Headlines and Titles One problem with he...

エレクトロニクス設計のプログラムマネージャーやチームマネージャーであれば、Allegro® System Captureなどの設計ツールを直接使って仕事をすることはまずないでしょう。それでも、ECADデータに素早くアクセスしたいケースもあります。具体的には、プロジェクトリスト、Live BOMデータ、Unified Search、パーツリクエスト、特定のデザインなどに。例えばデザインレビューや進捗状況把握、リスク評価などのため、これらのデータにアクセスする必要があります。 問題ありません...

The annual Jasper User Group was held in November. I've already written several posts about the event: Jasper User Group Preview Announcing Jasper C2RTL App: Formal for Algorithmic Designs Datapath Formal Verification 101: Technology and Techniq...

Allegro® Package Designer Plusの17.4-2019 HotFix 019より前のバージョンでは、デザイン上でClassがICタイプの部品はすべてDie-stack Editorに表示されます。もしその部品が既製の調達部品であるならば、Die-stack Editorに表示されるのは好ましいことではありません。既製部品がDie-stack Editorに表示されることを抑止するための対策として、部品のClassをdiscreteにする方法もあります。しかしなが...

Fast Fourier transform (FFT) is a very useful block in Automotive ADAS radar, communications, robotics, and image processing. The standard FFT architectures require data re-order (Radix-2 approach) or in-between data shuffling (Stockham approach) which provides limited performance. This work represents...

Cadence is thrilled to launch the first installment in our four-part blog series, spotlighting the outstanding recipients of our 2021 Diversity in Technology Scholarship program. This marks the fourth year for our Women in Technology Scholarship prog...

This is part 2 of my post on DAC and RISC-V from December. The first post is here . This post will cover Krste's presentation and then Calista back at the end to wrap up the conference and talk about the future. Krste Krste started on a similar ...

System Analysis Knowledge Bytesブログシリーズでは、Cadence®が提供するシステム解析ツールの機能と可能性について説明しています。 このシリーズは、この分野での役立つ機能等に関する学識を提供することに加えて、システム解析に関連する知識と経験を共有するブロガーと専門家の意見を広くお伝えすることを目的としています。 1965年、ゴードンムーアは、半導体産業の将来を予測しながら、高密度集積回路 (IC) 内のトランジスタ数が2年ごとに2倍になるとい...

Hello, everyone, and a happy new year! Last year was incredibly exciting for IC Packaging, with all the emerging options coming with silicon interposers, 3DIC innovations, and so much more. The options we are seeing continue to expand at lightning sp...

Any circuit you design uses parts that will vary depending on many factors that are not under your control. All components, such as resistors or capacitors, that you use have a tolerance. A 50Ω resistor with a precision of ± 1%, can vary between 4...

Due to the pandemic, events that normally occur earlier in the year all piled up in December. The Design Automation Conference, SEMICON West, and the RISC-V Summit all took place in the second week of December, with the International Electron Devices...

CES was and is officially hybrid, with some events on-site in Las Vegas and some online. But many of the large exhibitors pulled out of attending in person (including Cadence, although we might be a big exhibitor at DAC but at CES we are tiny). A lot...

The Cadence Scholarship Program is the flagship CSR program of Cadence India, introduced five years ago. Many meritorious students from under-served sections of society drop out of the education system after school because of the lack of finances. Th...

At the recent 2021 TSMC OIP Ecosystem Forum, there were two special presentations by TSMC "before" the usual partner presentations. I put "before" in quotes since the event was virtual, so in practice, you could watch stuff in any...
