根据目前的在线文档，Numonyx N25Q系列由Impact支持128Mbit大小。
此文档页面的URL表明这适用于（至少）ISE 12.4及更高版本。
听起来您可能需要更新您的Impact（或ISE）SW。
对于Spartan-3a来说，从12.3更新到12.4对于Spartan-3a来说应该是轻松的，并且对于Spartan-6来说几乎是无痛的，给予或重新生成任何MIG内核并更新速度文件。
如果你正处于一个项目中，我不会建议更新到13.1（等到项目结束，你应该 - 尤达）。

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。

According to current online docs, Numonyx N25Q series is supported by Impact through 128Mbit size. The URL of this doc page suggests this applies (at least) to
ISE 12.4 and later.
Sounds like you might need to update your Impact (or ISE) SW. Updating from 12.3 to 12.4 should be painless for Spartan-3a, and mostly painless for Spartan-6, give or take re-generating any MIG cores and updating speed files. I would not suggest updating to 13.1 if you are in the middle of a project (
wait until project is over, you should -- Yoda).

Summary:
1. Read the manual or user guide. Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
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.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts. If I write a good post, then I have been good for nothing.
