请问Spartan 6配置模式的潜在问题是什么？

鉴于Spartan-6内部“弱上拉”的最大电流为350uA  -  500uA，10K下拉R值太高，无法保证低逻辑电平。

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。

Given that the maximum current for a Spartan-6 internal 'weak pullup' is 350uA - 500uA, a 10K pulldown R is too high a value to guarantee a LOW logic level.

3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.

d，
我会在装配过程中检查焊剂清洗过程中是否有污染的水。

I would check if you have contaminated water during the wash of the flux during assembly.
