This application note provides a method to dynamically change the clock output frequency, phase shift, and duty cycle of the mixed-mode clock manager (MMCM) for the Xilinx® 7 series, UltraScale™, and UltraScale+™FPGAs. The V6 only had MMCMs. The PLL/MMCMs are usually part of the static region. In simulation I get a warning saying that I should reset the MMCM. The MMCM can easily and normally generate output clocks with frequencies that are higher (or lower) than the input clock frequency. I found a tap 'Phase Shift Mode' as the figure below. I suppose it boils down to how well one can speed-read though a lot of documents that are hard to find and notice the right reference. In Table3-4 , added a row of UltraScale+ device MMCM attributes for CLKFBOUT_MULT_F(1), page53, changed xilinx 7 シリーズには、mmcmといって、従来のpllやdcmをさらに進化させたクロック生成器が入っています。mmcmの最大の特徴はなんといっても、分数の分周比や逓倍比が設定できることです。 Datasheets for UltraScale devices typically show that the minimum output frequency of the MMCM is 4.

Chapters that need to use reference files will point to the specific ref_files subdirectory. This is the expected time. com 2 Divider Group Every clock output has a divider group associated with it. (VHDL Example). 0 ev aluation board and the tool versions in the Xilinx FPGA除了提供丰富的时钟网络之外，还提供了强大的时钟管理模块，并不断改进，从Virtex-4的纯数字管理单元DCM，发展到Virtex-5的CMT，再到Virtex-6基于PLL的混合时钟管理器（MMCM），实现了最低的抖动滤波，为高性能的FPGA设计提供了强大的时钟管 I'm using a Zync part (Xilinx Series-7) and trying to use the dynamic reconfiguration of the MMCM clock module whilst keeping the fine phase shift control enabled as I need both features. Description. mmcm/pll ip核简介。锁相环作为一种反馈控制电路，其特点是利用外部输入的参考信号控制环路内部震荡信号的频率和相位。因为锁相环可以实现输出信号频率对输入信号频率的自动跟踪，所以锁相环通常用于闭环跟踪电 混合模式时钟管理器（MMCM）除了丰富的时钟网络以外，Xilinx还提供了强大的时钟管理功能，提供更多更灵活的时钟。Xilinx在时钟管理上不断改进，从Virtex-4的纯数字管理单元DCM，发展到Virtex-5CMT（包含PLL），再到Virtex-6基于PLL的新型混合模式时钟管理器MMCM（Mixed-Mode Clock Manager），实现了最低的抖动和 I using Xilinx FPGA and need to use its PLL (MMCM or Clk Wizard) I have on my board LVDS 200MHz clock with 50 ppm frequency jitter, I took this and go to some converted I can find on the internet a Hello, Does this structure is allowed in the UltraScale architecture? What restrictions this structure has? Xilinx ® documentation is organized around a set of standard design processes to help you find relevant content for your current development task. Topics covered in this course: Creating a clock divider using an MMCM; Writing a custom clock divider in VHDL （6）将MMCM上的DEN和DWE信号拉高一个时钟周期 （7）等待MMCM的DRDY信号被拉起，循环上述操作，写入所有寄存器； （8）若所有的寄存器全部修改完成，释放MMCM的复位信号，等待MMCM的输出时钟锁存. At the end of the day, I really don't see any issues at 100 and 50 MHz either Interpolated Fine Phase Shift in Fixed or Dynamic Mode in the MMCM. The Kintex-7 and many other FPGAs from Xilinx have the MMCM clock module. com 2 through the DRP port. Thus the MMCM can do everything the PLL can do plus the phase shifting from the DCM. Example: Converting Xilinx* MMCM into an Intel® PLL. Date 3/20/2018. Information about this and other Xilinx LogiCORE IP modules is available at the Xilinx Intellectual Property page. But the simple answer is no again, see the user guide but "The MMCM automatically locks after power on. Download. UG911. So do I need to do this when using it in the hardware? VIVADO Clocking_Wizard IP配置 打开block design，点击“+”，输入clk即可选择Clocking_Wizard 在clock options页面 Clock Monitor选项是时钟监控，一般情况下不勾选 Primitive中MMCM包含PLL（一般选MMCM） Clocking Features Frequency Synthesis选项是允许输出时钟具有不同频率，就是输入和输出的频率可以不同； Phase Alignment是相位 Hi, I have a question regarding reset timing in MMCM (I'm using XCKU040 in simulation). Se n d Fe e d b a c k. Design Suite under the terms of the Xilinx End User License. 8) August 20, 2019 www. For most FPGA designs, a reference input clock is used to generate other required clocks in the design using PLL/MMCMs. Customers should click here to go to the newest version. This has the effect of improving the common node, and hence greater clock pessimism removal is seen. 16 前言 在我们的一个应用中，采用ADC采集数据，ADC的采样时钟信号由FPGA提供。 virtex-6的cmt包含2个mmcm，处于同一个cmt中的2个mmcm之间有专门布线资源。每个时钟片里的mmcm可以独立使用，也可以将mmcm之间的专门布线资源释放出来供其他设计单元使用。 mmcm之间的连接关系及输入源的框图如图5-12所示。 In Virtex-6 the MMCM - Mixed Mode Clock Manager - was introduced.

Date 4/01/2024. The question is, is it worth it to set the MMCM receiving this clock with the 'minimize output jitter' option, and use its (unchanged frequency-wise) output clock to drive another MMCM, in order to have Chapter 1: Using Constraints Tutorial This tutorial discusses different methods for defining and applying design constraints. The MMCM and PLL Configuration Bit Groups section presents the configuration bits as five bit groups, and provides an overview of their usage. ID 683562. A mixed-mode clock manager is si The MMCM is the primary block for frequency synthesis for a wide range of frequencies, and serves as a jitter filter for either external or internal clocks, and deskew clocks among a wide This application note provides a method to dynamically change the clock output frequency, phase shift, and duty cycle of the mixed-mode clock manager (MMCM) for the Xilinx® 7 series, The MMCM primitive in Virtex™ 6 parts is used to generate multiple clocks with defined phase and frequency relationships to a given input clock. 2 design, where I want to minimize the output clock jitter. 333 MHz になるため、MMCM の周波数 由于场景需求，需要动态调整输出时钟的相位，因此，本文主要讲述了如何使用MMCM进行动态调整输出时钟相位。 概述; MMCM的使用方法，最好先看一下文档：ug472_7Series_Clocking. Interpolated fine phase shift (IFPS) mode in the MMCM has linear shift behavior independent of the CLKOUT_DIVIDE value and the phase shift resolution only depends on the VCO frequency. However, UG572 suggest that sometimes the reset time might be longer. I do have several MMCMs in my design. I didn't found any simulation model for the clock managers. <p></p><p></p> Learn about the two types of generated clocks in Vivado: clocks automatically derived by the tools and user-defined generated clocks. 2 Reconfiguration Module Ports.
