A：这个问题可以参考高老亚军师公众号（FPGA技术驿站）中的一篇文章。在文中提到： 对于发送时钟和接收时钟是同一时钟的单周期路径，时钟抖动对建立时间有负面影响，但对保持时间没有影响。这一点，在Vivado的时序报告中也可以看到。如下图所示，图中 ...

在开关电源的计算中，往往涉及到三角波电流（如图1）的计算，本内容详细的介绍其平均电流Iavg、均方根RMS以及交流分量的计算。充分地理解公式远不止于记住它的形式和计算结果。真正的要义在于融会贯通，在于从掌握走向自如运用。1、平均电流Iavg的计算 ...

Sunnyvale, California - November 5, 2008- Real Intent, Inc., the leading supplier of verification software for electronic design, announced its first release of Meridian FPGAâ„¢ verification software.

高端FPGA是片上系统（SoC）器件，内置处理内核，例如ARM Cortex内核，它们具有自己的一套参考时钟，或者，它们具有嵌入式串并转换器（SERDES），为了满足最终应用的误码率（BER）规范，而对抖动具有严格要求。 现场可编程门阵列（FPGA）在众多高性能应用中 ...

It used to be that designing hardware required schematics and designing software required code. Sure, a lot of people could jump back and forth, but it was clearly a different discipline. Today, a lot ...

[John] wanted a project to help him learn more about FPGAs. So he started with his wooden clock — made with an Arduino — and ported it over to a Lattice FPGA using Icestorm. What’s nice is that he ...

No discussion on FPGA design is complete without addressing the issues associated with transferring signals that are not synchronized to the clock into clocked logic. While this should be a digital ...

Californian start-up Achronix has revealed details of its 1.5GHz asynchronous FPGA, which includes 10.3Gbit/s serialiser/deserialisers (serdes). “We get our speed from the underlying silicon ...

随着5G、AI和云计算平台的兴起，高性能FPGA在这些新兴市场又找到了新的机遇。然而，全球两家最大的FPGA公司却无法独立存在，这是否意味着FPGA无法成为独立的市场呢？国产FPGA厂商在高端市场难以跟英特尔和赛灵思竞争，而在中低端市场又有什么机会呢？

Clock domain crossings are significant sources of field system failures. Despite this fact, designs continue to be released without fully verified CDCs. A false sense of security resulting from ...

A few years ago the market was rife with deep learning chip startups aiming at AI training. This, however, is the year of the inference ASIC. But with millions invested in taping out a new chip in an ...
