谁知道这个错误是关于什么的?
我从未遇到过问题之前运行相同的UCF,但现在在映射时它给我一个错误:pack:2908可以在xilinx数据库中找到任何内容。 使用ise 13.1 以上来自于谷歌翻译 以下为原文 anyone know what this error is about? i run the same UCF before never had issues, but now at mapping it give me an error:pack:2908 could find anything in xilinx data base. using ise 13.1 |

消除过程的好抓!
看起来 IOSTANDARD = LVDS_25; // *不好。 IOSTANDARD = LVDS25; // 好 如果PlanAhead生成了错误的.UCF文件语法,则表示您应该报告的错误(请打开Webcase)。 目前尚不清楚该错误是出现在PlanAhead中是为了生成错误的语法,还是在ISE中的某个其他地方出现不一致的约束形式处理,或两者兼而有之。 如果您错误地手动指定了IOSTANDARD,那么问题就解决了。 在任何一种情况下,请将此主题标记为“已解决”,并接受我们的谢意,以便发现并记录它。 - 鲍勃埃尔金德 签名:新手的自述文件在这里:http://forums.xilinx.com/t5/New-Users-Forum/README-first-Help-for-new-users/td-p/219369总结:1。 阅读手册或用户指南。 你读过手册了吗? 你能找到手册吗?2。 搜索论坛(并搜索网页)以寻找类似的主题。 不要在多个论坛上发布相同的问题。 不要在别人的主题上发布新主题或问题,开始新的主题!5。 学生:复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。 提供有用的详细信息(请与网页,数据表链接).7。 您的代码中的评论不需要支付额外费用。 我没有支付论坛帖子的费用。 如果我写一篇好文章,那么我一无所获。 在原帖中查看解决方案 以上来自于谷歌翻译 以下为原文 Good catch by process of elimination!

错误是I / O组件“io_p”具有非法的IOSTANARD值LVDS_25。
我看vhd缓冲区的ibfudsgeneric地图(iostandard =>“LVDS_25”,IFD_DELAY_VALUE =>“0”,DIFF_TERM => TRUE) 以上来自于谷歌翻译 以下为原文 the error is I/O component "io_p" has illegal IOSTANARD value LVDS_25. i look the vhd buffer its ibfuds generic map( iostandard => "LVDS_25", IFD_DELAY_VALUE => "0", DIFF_TERM => TRUE) |

错误是I / O组件“io_p”具有非法的IOSTANARD值LVDS_25
在同一个IO银行中使用了哪些其他IOSTANDARD? 该信号所在的IO bank的VCCO是什么? 这个信号是差分对的一半吗? LVDS用于差分信号,而不是单端信号。 - 鲍勃埃尔金德 签名:新手的自述文件在这里:http://forums.xilinx.com/t5/New-Users-Forum/README-first-Help-for-new-users/td-p/219369总结:1。 阅读手册或用户指南。 你读过手册了吗? 你能找到手册吗?2。 搜索论坛(并搜索网页)以寻找类似的主题。 不要在多个论坛上发布相同的问题。 不要在别人的主题上发布新主题或问题,开始新的主题!5。 学生:复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。 提供有用的详细信息(请与网页,数据表链接).7。 您的代码中的评论不需要支付额外费用。 我没有支付论坛帖子的费用。 如果我写一篇好文章,那么我一无所获。 以上来自于谷歌翻译 以下为原文 the error is I/O component "io_p" has illegal IOSTANARD value LVDS_25 what other IOSTANDARDs are in use in the same IO bank?

错误发生在virtex 5 sx240t部分的第11行。
LVDS对在vhdl中使用ibufds进行了实现,在UCF中我也为该对编写了约束 ... iostandard = lvds_25 | differ_term = true; 第11行中的所有其他对都是lvds_25,并且这对没有任何问题。 我不认为逻辑也是优化的。 它之前没有这个问题但是现在.. 以上来自于谷歌翻译 以下为原文 the error is at bank 11 in virtex 5 sx240t part. the LVDS pair was instiantiate with ibufds in vhdl, in the UCF i also wrote constraint for that pair ... iostandard = lvds_25 | differ_term = true; all other pairs in bank 11 are lvds_25 and don't have any problems just this pair. i don't think the logic is optimize out either. it doesn't has this issues before but now.. |

您也引用了哪种语法错误?
bank 11是输入和输出lvds的混合,仅有1个输出对。 是的,忘记了它的diff_term,是的,在ucf中它的语法正确。 关于那个 以上来自于谷歌翻译 以下为原文 which syntax error are you refer too? bank 11 is mix of input and output lvds, althouth only 1 output pair. yea forgot its diff_term, yeah in the ucf its in correct syntax. sry about that |

建议:
从.UCF(和PlanAhead)中删除对此输入差异对的所有引用和赋值。 让ISE弄清楚如何处理这两个引脚。 检查后PAR总结以查看ISE是否做了正确的事情(例如,没有修剪,被视为差异对)。 使用此输入对使ISE“满意”后,将所需的约束添加回来...一次一个。 查看哪些约束(或约束组合)会引发错误消息。 使用反复试验,消除过程追逐这一点。 - 鲍勃埃尔金德 签名:新手的自述文件在这里:http://forums.xilinx.com/t5/New-Users-Forum/README-first-Help-for-new-users/td-p/219369总结:1。 阅读手册或用户指南。 你读过手册了吗? 你能找到手册吗?2。 搜索论坛(并搜索网页)以寻找类似的主题。 不要在多个论坛上发布相同的问题。 不要在别人的主题上发布新主题或问题,开始新的主题!5。 学生:复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。 提供有用的详细信息(请与网页,数据表链接).7。 您的代码中的评论不需要支付额外费用。 我没有支付论坛帖子的费用。 如果我写一篇好文章,那么我一无所获。 以上来自于谷歌翻译 以下为原文 Suggestion: Remove all references and assignments to this input diff pair from the .UCF (and PlanAhead). Let ISE figure out what to do with these two pins. Check the post PAR summary to see if ISE 'did the right thing" (e.g. no trimming, treated as diff pair). After you make ISE 'happy' with this input pair, add the desired constraints back in... one at a time. See which constraints (or combination of constraints) provokes error messages.

好吧看起来像IOSTANDARD = LVDS_25;
在.ucf导致此错误,一旦它注释掉,它运行正常并自动设置为lvds25。 不确定为什么因为所有其他对具有相同的约束语法。 以上来自于谷歌翻译 以下为原文 ok look like IOSTANDARD = LVDS_25; in .ucf is causing this error, once its comment it out, it runs fine and sets to lvds25 automatically. not sure why since all the other pairs has same constraint syntax. |
