在 PHY 从 P2 状态退出时,PHY 需要尽可能快地置高 PhyStatus,并且保持置高状态,直至 PCLK 稳定。 PCLK as PHY Input: 该模式下,当 PHY 状态转移为 P2 时,PHY 需要置高 PhyStatus 一个输入时钟周期,表示其准备好关闭 PCLK。在 PHY 从 P2 状态退出时,PHY 需要尽可能快地置高 PhyStatus 一个输入时钟周期...
对于那些使用 CLKREQ# 来触发进一步电源管理措施的应用来说,PIPE 协议兼容 PHY 需要满足下述要求: CLKREQ# in L1 当MAC 将链路转移到 L1 状态,并且打算置低 CLKREQ# 以停止 REFCLK 时,在链路进入 L1 状态后,MAC 不是和通常一样将 PHY 转移为 P1 状态,而是直接将 PHY 转移为 P2 电源状态后,MAC 置低 CLKRE...
Introduction The memory controller logic and PHY interface represent the two primary design elements in DDR memory systems, which are used in virtually all electronic system designs, from cellphones and set-top boxes, to computers and network routers. These two components of the memory system requir...
DDR PHY Interface(DFI) provides an smart way to verify the DFI component of a SOC or a ASIC. The SmartDV's DDR PHY Interface(DFI) is fully compliant with standard DFI Specification and provides the following features. DFI Memory Model is supported natively inSystemVerilog, VMM, RVM, AVM, ...
现代电子系统设计中,经常将DDR内存接口分成内存控制逻辑(MC,Memory Controller)和物理层接口(PHY,Physical Interface)两个部分。这两个部分侧重点不同,往往需要不同的设计技巧和设计经验。随着IP(intellectual property)厂商的发展,越来越多的工程师选择在...
现代电子系统设计中,经常将DDR内存接口分成内存控制逻辑(MC,Memory Controller)和物理层接口(PHY,Physical Interface)两个部分。这两个部分侧重点不同,往往需要不同的设计技巧和设计经验。随着IP(intellectual property)厂商的发展,越来越多的工程师选择在设计中采用第三方的IP核,来加速项目进度。这就带了问题,由于MC和...
Overview 1.0 Overview The DDR PHY Interface (DFI) is an interface protocol that will allow efficient connectivity to a DDR memory controller. The interface was designed to maximize performance, provide a rich set of features, and minimize the cost of integration of a DDR memory controller to a...
