The only related issue that I've run into involves naming projects, directories that store projects, etc. Some of the utilities that ISE calls (still?) do not handle spaces in the filename string. Some notable problems with Windows might be "My Documents" or "Program Files." This can also be a problem with Linux because they don't call the executables properly (ie with quotes for arguments, or whatever) I've also seen filename LENGTH problems. These problems show up multiple places, not the least of which, in the EDK for MicroBlaze, their 32-bit softcore processor. The error messages that result are not always file-not-found errors ---- you get cryptic errors that won't directly point you to the root cause. Oh, and one other thing: Make sure you "cleanup" the project in Windows ISE before you move things. There are a bunch of intermediate files that store directory related items that won't be there in the new file system. Even moving projects from directory to directory within Windows this problem can show up. It's not a big deal --- just keep an eye out for it. Once again, the error messages you get will not easily point right at this being an issue. The main thing is that if you instantiate a module, and that module is in the project, but can't be found when synthesizing, then you need to cleanup and rebuild. If you are familiar with the icons in the project navigator, the modules not having the correct icon next to them will usually indicate that this needs to be done. In general, if you synthesize and get weirdo errors related to "no such module", then cleanup and rebuild. It almost always fixes the problems. Keith
