Verification: LPDDR5 Verification from PHY to System Level

Vinod Khera

LPDDR5 DRAM aims to serve a wide array of markets and plays a vital role in the system’s performance. These performance expectations make the whole system verification extremely challenging and become more complex as the project evolves from IP Level verification to Memory sub-system and System-level as you start integrating the memory pieces in the whole SoC. In this blog, I will be discussing how Cadence helps to overcome…

Breakfast Bytes: Intelligent System Analog Design

Paul McLellan

There are many perceptions about analog design that might have been true once. For example, all analog design is done by grey-haired designers with decades of experience wrestling the signals to the ground using just a polygon-based layout editor and...

PCB設計／ICパッケージ設計: BoardSurfers: Allegro PCB Editorでの寸法データ入力に関する概要

SPB Japan

プリント基板がより複雑かつ軽量になっていく中、費用対効果が高く信頼性の高い基板の設計・製造は、これまで以上に重要となっています。デザインの詳細情報が不正確／不完全では、アセンブリの工程で基板の製造に影響を与える可能性があります。PCBデザインに寸法データ(ディメンジョン)を追加することにより、そのPCBデータが製造用に出力されたときにすべてがぴったり合うようデザインに関する十分な詳細情報を提供できます。なぜ寸法データが必要なのか？ PCBに寸法データを付加する主な目的は、重要な穴の位置、PCB...

Computational Fluid Dynamics: Combining Structured and Unstructured Meshes: The Holy Grail for CFD Engineers

AnneMarie CFD

Flow solvers must be able to read the type of meshes behind them, and as most flow solvers only accept either structured or unstructured meshes, this is can be a no-win situation. However, within Cadence's Omnis™︎ environment, users can switch between meshing approaches in a single click.

CFD（数値流体力学): Illinois Blowerは流体シミュレーションによってファンの性能を44％改善

CFD Japan

石油化学およびその他の産業では、空気の換気や500°C以上の有害な塩化物ガスの処理のためにファンを使用しています。これらのファンの最大運転回転速度は業界標準によって管理され、しばしば制限されています。この制限により、ファンメーカーは所望の圧力出力を得るために、インペラの直径を調整することを余儀なくされます。エンジニアは、結果として得られる設計が特大サイズになったり、重くなったり、製造、試験、輸送にコストがかかったりすることを回避しなければなりません。イリノイ州ケーリーに拠点を置くIll...

Computational Fluid Dynamics: CFD Wind Studies for Ship Superstructures

AnneMarie CFD

Besides resistance, seakeeping and propulsion, wind loads play an important role in navigation, and wind studies form an essential part of marine engineers' and naval architects' work. Since model tests are expensive and wind tunnel availabilities don't always match project deadlines, CFD simulations become a powerful tool, allowing designers to understand the effects of design changes on their projects quickly and accurately…
