Quartus II 7.1 - SOPC Builder New Component

It seems that in 7.1, no original design files will be copied to the project directory. All the generated design files are instantiations of the original design files(file wrappers), except for the top level sopc design file.

When doing synthesis and analysis, we should add the original design files manulally in the Files page of the Settings menu.

This is different from previous versions of Quartus. I think this is an improvment. Let the Synthesizer do the file locating job. The Component editor only checks the interface signals but not those lower level files.
