  • PCB、IC封装:设计与仿真分析: PCB设计团队如何在布线之前发现并解决信号完整性问题

    Sigrity
    Sigrity
    PCB设计团队面临的一个主要挑战是如何确保设计的按时签发。由于信号完整性工程师通常只能在设计周期的后期发现问题并提出更改要求,设计师们于是不得不一遍又一遍地重复设计 - >布线 - >重新布线这一循环。当SI专家发现与基本反射相关的SI问题如不正确的布线拓扑结构、丢失的终止信号、过冲、回铃或延长的延迟建立时,设计师们的工作则必须重头再来。这一切都令人感到沮丧,特别是当SI专家知道这些基本问题其实可以更早地得到解决。 在设计后期发现问题,意味着设计团队之前投入的布线精力都白费了,他们...

  • Digital Design: 2018 Annual HLS Survey Results

    dpursley
    dpursley

    Earlier this year, we performed the annual high-level synthesis (HLS) industry survey to get an idea of the industry’s expectations of HLS. As in last year’s survey, approximately half of the responses were from current HLS users, and half were from non-users. This year’s anonymous survey focused on HLS usage and expectations.

    As usual, I’ll walk through the questions one by one below, but first let…

  • Digital Design: ECO with Stratus HLS and the Digital Implementation Flow

    dpursley
    dpursley

    For years chip designers have dealt with ECO’s when their source code was written in RTL. But the move to high-level synthesis (HLS) means that their source code is now one step further removed from the gate level netlist. This naturally leaves a question, “What if I need an ECO on my Stratus project?”

    First and foremost, it’s important to understand that ECO’s are less common in the HLS flow. I’ll explain…

  • PCB、IC封装:设计与仿真分析: 针对电气工程师的热管理基础——第四篇

    Sigrity
    Sigrity
    作者:Lawrence Der 在热管理基础知识的第一篇中,我们讨论了电域和热域之间的二元性。第二篇中,我们研究了三种不同的热传输机制,并将它们与等效热阻相关联。第三篇中,我们使用热电阻的概念建立了系统的热等效网络,并确定了其等效连结环境(JA)热阻。 通过这种方法,我们能够将热阻与系统的物理特性联系起来,并通过等效的热电阻方程直观地了解主要的热传输机制。现在,让我们来进入大家关心的究极问题:散热。 散热片 散热片是被动热传输器件。在将热量从IC封装传递到周围环境时,其热阻远小于由热对流和热辐...

    作者: Lawrence Der 在热管理入门基础知识——第二篇中,我们研究了三种不同的热传输机制,并将它们与等效热阻相关联。为了加深对热域的理解,此篇文章中我们将使用热阻的概念来建立一个系统的热等效网络,并确定与其等效的连结环境热阻。 作为电气工程师,我们必须保证的最基本的热要求之一,便是确保集成电路(IC)不超过其最高结温。根据热阻的概念,如果我们知道从IC结到周围环境的等效热阻、IC的最大结温和IC的最高环境温度,就可以估算出IC可具有的最大功耗,用下式表示: ...
