Info: Compilation Report contains advance information. Specifications for device EP3SE50F484C3 are subject to change. Contact Altera for information on availability. No programming file will be generated.
原因：对Quartus 7.2而言，3S系列是advanced devices，而advanced devices的.sof和.pof文件的产生是password-controlled。
解决：可以换更高版本的软件。


若此时编译后仍不能产生.sof和.pof文件，则运行assembler（assignment->start）。
