使用Exploreahead和planahead时地图错误

Pack：1107错误是用于报告与IO相关的各种打包问题的通用错误消息。
因此，在假设它是相关的之前，您需要考虑答复记录中描述的错误的上下文。
这就是为什么我在AR中放置限定词“这个答案记录只适用于你的情况......”。
您的错误消息中清楚地描述了您的问题。
您的pad和ibuf已通过约束分配给两个不同的区域组。
如果通过删除两个中的一个来修复区域组定义，则问题应该消失。
您可能希望了解是否存在更普遍的问题，例如具有意外后果的通配符约束。

以下为原文

The Pack:1107 error is a general purpose error message used to report  a variety of packing problems related to IO. So you need to consider the context of the error described in an Answer Record before  assuming it is relevent. That's why I put the qualifier "this answer record is only a good match for your case if ..." in the AR.
 
Your problem is clearly described in your error message. Your pad and ibuf have been assigned by your constraints to two different area groups. If you fix your area group deinitions by removing one of the two entrys, the problem should go away. You may want to look into whether you have a more general problem like wildcard constraints having unintended consequences. See the following AR for an example:
