PCB、IC封装：设计与仿真分析: 如何在PCB设计中进行DDR布线？

TeamAllegro

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...

Verification: How AMBA CHI Specification Has Evolved - CHI-E (r)evolutionary?

MinL

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 sub releases (E.a and E.b).

2020 (CHI-E.a) Issue E.a – update

Issue E.a added new transaction types such as Write*Zero…

Verification: System Verification Scoreboard: Its Role and Partnership with Verification IPs

DimitryP

As discussed in the last installment of the blog, a robust system level scoreboard is essential for functional verification and performance validation of modern SoCs.

A properly architected system scoreboard should work in conjunction with interface Verification IPs (VIPs) and share verification responsibilities. It should monitor all ports on an SoC’s interconnect, deploying clever algorithms to track transactions as…
