QuartusII中找不到.sof文件 sof, QuartusII, 文件

在QuartusII7.2中，构建niosII，编译等都正确，但是在向开发板下载是找不到.sof文件，这是怎么回事啊。我用的是30天免费版的，又影响吗。还请各位高手赐教！

yes ,if you use time-limited version ,the quartus will generate time-limited sof.And if the build is successful,the sof should be generated. you can download some license from this forum,and use privately.
