小生在用quartus II打开一些工程文件时,出现了如下的错误提示,一直不知道是什么原因,这才刚开始学习就卡住了,希望各位大神能帮忙解答,实在感激不尽!(注:已经把工程文件放在了英文路径下) can't open project——Quartus II Setting File contain one or more errors. unable to load logiclock assignments.Either there is no open project,or the Quartus II setting File for the project is corrupted or missing.
