DC综合：File is not a DB file. (DB-1)

哈哈一笑

各位大侠, 小弟在用DC综合时碰到如下怪象：


1）综合过程顺利通过，基本满足设计要求

2）诸如如下：Error: File is not a DB file. (DB-1)的error不断报出


在下久思未解，敢请坛子中的大侠指点迷津，多谢！

文件类型不对吧

艾清别诺

db文件時是*.db格式，需要寫出你需要db文件的路徑

check the following env settings are set.
search_path
target_library
link_library

我也碰到了同样的问题！解决办法是将在/home下的工作文件，放置到/usr下即可！

我解决了，原因之前我将db文件复制了一份，但中途使用Ctrl+C打断了，导致文件其实是残缺的，通过查看大小发现的。
遇到该问题的朋友需要检查你的db文件大小是否合理，并找到原先正确地db文件重新复制一份。
