我想知道我项目中的时钟结构,但是当我打开时钟摘要时,我的源代码中找不到一些时钟信号。 怎么解释这个现象? 是否有任何文件描述时钟摘要详述? BR 蓝翔 以上来自于谷歌翻译 以下为原文 Hi All I want to know the clock structure in my project,But when I open the Clock Summary,there are some clock signal I can't find in my source code. How to explain the phenomenon? Are there any document describes the clock summary detailed? BR lanxiang |

嗨,
您在此处看到的名称是由create_clock或create_generated_clock约束创建的时钟。 如果使用这些约束的-name选项,则将在此处报告使用-name指定的名称。 这就是你在RTL中找不到这个的原因。 打开实现的设计后,您可以在TCL控制台中运行report_clocks命令。 这列出了设计中的所有时钟及其来源。 使用这些源可以将它们与RTL相关联。 谢谢, 迪皮卡。 谢谢,迪皮卡.---------------------------------------------- ---------------------------------------------- Google之前的问题 张贴。 如果某人的帖子回答了您的问题,请将帖子标记为“接受为解决方案”。 如果你看到一个特别好的和信息丰富的帖子,考虑给它Kudos(左边的明星) 在原帖中查看解决方案 以上来自于谷歌翻译 以下为原文 Hi, The names you see here are the clocks which are created by create_clock or create_generated_clock constraints.

你好,
这里有一些命令可以帮助您分析设计中的时钟。 report_clocks:此命令将在表中返回设计中的所有时钟。 report_clock_interaction:该命令报告时钟交互和跨时钟域的信号,以识别这种亚稳态的潜在问题。 report_clock_networks:返回设计中每个时钟网络的网络扇出。 要了解有关这些时钟摘要相关命令的更多详细信息,请查看以下UG, http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug835-vivado-tcl-commands.pdf 问候,阿希什----------------------------------------------- - - - - - - - - - - - - - - - - - - - - - - - -请注意- 如果提供的信息有用,请将答案标记为“接受为解决方案”。给予您认为有用且回复的帖子。感谢Kudos .-------------------- -------------------------------------------------- ------------------------ 以上来自于谷歌翻译 以下为原文 Hello, Here are few commands which can help you to analyze clocks in your design. report_clocks : This command will return all clocks in your design in a table. report_clock_interaction : This command reports clock interactions and signals that cross clock domains to identify potential problems such a metastability. report_clock_networks : Returns the network fanout of each clock net in the design.

嗨,
您可以在http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug903-vivado-using-constraints.pdf中找到这些详细信息。 使用传播,生成等关键字进行搜索 谢谢, 迪皮卡。 谢谢,迪皮卡.---------------------------------------------- ---------------------------------------------- Google之前的问题 张贴。 如果某人的帖子回答了您的问题,请将帖子标记为“接受为解决方案”。 如果你看到一个特别好的和信息丰富的帖子,考虑给它Kudos(左边的明星) 以上来自于谷歌翻译 以下为原文 Hi, You can find these details in http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug903-vivado-using-constraints.pdf Search with keywords propagated, generated etc. Thanks, Deepika.

你好,
传播时钟:这些是通过时钟树传播的时钟,它引入了网络延迟和不确定性。 默认情况下,Vivado始终将时钟视为传播时钟。 生成时钟:这些是使用从a生成的create_generated_clock命令定义的派生时钟 主物理时钟喜欢MMCM / PLL / BUFR。 虚拟时钟:虚拟时钟是一个时钟,它没有物理连接到设计中的任何网表元素。 更多细节可以在UG903的第58页找到 倒置时钟:时钟可以被路径上的任何单元反转,具体取决于定时弧的性质。 例如,反相器输入端的上升沿成为输出的下降沿。 更多细节可以在 http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug903-vivado-using-constraints.pdf http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug906-vivado-design-analysis.pdf 问候,阿希什----------------------------------------------- - - - - - - - - - - - - - - - - - - - - - - - -请注意- 如果提供的信息有用,请将答案标记为“接受为解决方案”。给予您认为有用且回复的帖子。感谢Kudos .-------------------- -------------------------------------------------- ------------------------ 以上来自于谷歌翻译 以下为原文 Hello, Propogated Clock : These are the clocks which are propogated through the clock tree which introduces network latency and uncertainty. By default Vivado always treats clocks as propogated clocks. Generated Clock : These are the derived clocks defined with the create_generated_clock command generated from a primary physical clock likes MMCM/PLL/BUFR. Virtual Clock : A virtual clock is a clock that is not physically attached to any netlist element in the design. Further details can be found at page no 58 of UG903 Inverted Clock : The clock can be inverted by any cell along the path, depending on the nature of the timing arc. For example, a rising edge at the input of an inverter becomes a falling edge on the output. Further details can be found at http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug903-vivado-using-constraints.pdf http://www.xilinx.com/support/documentation/sw_manuals/xilinx2014_2/ug906-vivado-design-analysis.pdf Regards, Ashish ---------------------------------------------------------------------------------------------- Kindly note- Please mark the Answer as "Accept as solution" if information provided is helpful.
