如果我的目标设备有10个MMCM。
这是否意味着我可以通过IP目录创建10个不同的MMCM模块,并在设计中实例化它们? 非常感谢。 以上来自于谷歌翻译 以下为原文 If my target device has 10 MMCMs. So does this mean that I can create 10 different MMCM modules through IP catalog, and instance them in the design? Thanks very much. |

绝对地,每个MMCM可以接受不同的时钟输入,生成不同的VCO频率并生成不同的分频输出频率。一个可能的冗余评论是每个MMCM支持多个分频输出。
因此,如果您需要来自同一源的多个相关时钟,则无需为每个输出使用不同的MMCM。 实际上,如果时钟输入没有不同,那么拥有多个MMCM的原因并不多。 - 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。 在原帖中查看解决方案 以上来自于谷歌翻译 以下为原文 Absolutely, each MMCM can accept a different clock input, generate a different VCO frequency and generate different divided output frequencies. One potentially redundant comment is that each MMCM support multiple divided frequency outputs. So if you need several related clocks from the same source, there is no need to use different MMCMs for each output. Actually if clock inputs are not different there are not many reasons to have more than a few MMCMs.- Please mark the Answer as "Accept as solution" if information provided is helpful.

您不必创建10个不同的MMCM IP块。
您只能创建一个并将其实例化10次。 MMCM非常易于配置,您无需为每个小配置选项转到IP块。 - 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。 以上来自于谷歌翻译 以下为原文 You don't have to create 10 different MMCM IP blocks. You can create only one and instantiate it 10 times too. MMCMs are very easy to configure, you don't have to go to the IP blocks for every small configuration option.- Please mark the Answer as "Accept as solution" if information provided is helpful.

好的,这意味着我的设备中有10个MMCM。
我可以最多实例化它们10次,每个实例将使用1个MMCM,对吧?如果我以另一种方式说可能更好理解,每个MMCM可以有不同的配置。谢谢。 以上来自于谷歌翻译 以下为原文 Ok, so that means if I have 10 MMCMs in the device. I can max instantiate them 10 times, each instance will use 1 MMCM, right? If I say in another way may be better to understand, each of MMCM can have different configurations. Thanks. |

嗨佛,
对,就是这样。 如果设备中有10个MMCM,则可以将它们实例化最多10次。 是的,每个实例都将使用1MMCM。 这就是实例化的意思。 coregen工具为每个核心实例化1个MMCM。 您可以打开代码并检查原始实例化。 但是,如果您对每个MMCM有不同的要求,那么您需要10个不同的coregen生成的核心来支持这些特性。 您的查询是否已回答? 谢谢,AnirudhPS:请将此标记作为答案,以防它有助于解决您的问题。如果帖子引导您找到解决方案,请给予赞誉。 以上来自于谷歌翻译 以下为原文 Hi Buddha, Yes, exactly. When you have 10 MMCM's in the devices you can instantiate them for a max of 10 times. Yes, each instance will use 1MMCM. That is what instantiation means. The coregen tool intantiates 1 MMCM for each core. You can open the code and check the primitive instantiation. However if you have a different requirement from each MMCM then you need 10 different coregen generated cores supporting those charcteristics. Is your query answered? Thanks, Anirudh PS: Please MARK this as an answer in case it helped resolve your query.Give kudos in case the post guided you to a solution. |
