Cadence Cloud started before there even was a cloud. We just didn't call it Cadence Cloud. Back in the early 2000s, when I was on my first tour of duty at Cadence, we created something that we called Virtual CAD, or VCAD for short. The idea was that ...

DFT (Design for Testability) provides the much-needed support to the manufacturers to catch up with the increasing demand and pressure for mass production. It helps produce chips with flawless design and perfect quality for challenging applications. ...

This month the In-Design Analysis (IDA) team kicked off its new blog program with an insightful look at "High-Tech Everything” from group director Sherry Hess and advice from our Celsius expert Melika Roshandell on "Finding and fixing thermal issues early in the PCB design flow."

本文作者：Yannick Baux, Cadence产品研发总监 space 汽车行业一直使用 CFD 工具来设计和优化车辆的各个方面，从外部空气动力学到降噪，再到热管理、内部燃烧等等。大多数情况下，在设计过程中，所有上述内容被结合在一起，称为虚拟原型，以便将车辆作为一个系统进行优化。然而，各种应用背后的物理原理往往大不相同，这就意味着需要为每个特定的应用采用专门的技术。因此，设计师、科学家或工程师经常使用大量不同的 CAE 代码和软件工具，这些工具都有不同的界面（GUI）、数据设置、...

The Cadence Education Kit initiative runs at full steam! After the release of the VLSI Fundamental: A Practical Approach Education Kit and the Tensilica Education Kit , there is a new kit knocking on the door of all microelectronics educators: the Fun...

At the recent D&R IP-SoC Day 2022, Amol Borkar presented Designing the Next Ultra-Low Power Always-On Solution. Amol is a product marketing director for the Cadence Tensilica product line. He started with some statistics about Tensilica. Tensilic...

DDR布线技术的重要性 在如今的印刷电路板设计中，双数据速率（DDR）存储器非常普遍。许多设计都会用到DDR存储器配置的不同版本，这需要在布局中使用特定的布线模式。DDR的名称来源于其能够在每个时钟周期内发送和接收两次信号，是原先的单数据速率（SDR）存储器速率的两倍。由于速率增加了一倍，必须在布设DDR存储器的走线时保持更严格的参数，以满足性能规范。 存储器电路设计的关键在于满足其时序规范。每个信号都有时间要求，以便于对应的时钟信号在上升沿和下降沿对其采样。由于数据速率在DDR存储器的每次新迭...

We covered CHI specification revisions A to D in my previous article , what about Issue E? Issue E was by far the biggest update yet with a slew of new transactions, optimization features to interface behavior and architecture, and spec clarifications and corrections. It spanned two years and two...

本文要点： 所有的物理系统在运行动态中都会表现出一些瞬态行为，电子产品也是如此 瞬态分析技术可以帮助了解不同电气状态之间的转换 当检查测量数据或软件仿真数据时，一些基本的瞬态分析技术可用于了解电气状态之间的转换 时域瞬态分析技术在时域中运用，全面展现了不同状态之间的信号转换过程 当打开或关闭 LED 时，随着光线变亮或变暗有一个缓慢的过渡。这种类型的瞬态行为非常简单，但这是一个电子系统改变状态时的基本反应。使用瞬态分析可以充分理解时域中的信号转换，以及它们与重要系统参数的关系。 初次接触软...

The Ministry of Electronics and Information Technology (MeitY) organized a unique conference this past weekend called SemiconIndia 2022. Inaugurated by Prime Minister Modi, other dignitaries from the government of India included Minister of Electroni...

Recently, it was D&R's IP-SoC Silicon Valley 2022. The opening keynote was given by Gabrièle Saucier, the CEO of D&R. It was also the 25th anniversary of D&R. But I met Gabrièle years before that. In December 1986, I rel...
