Is there a way to tell Quartus where to put the ./db and ./incremental_db directories on a per-project and per-revision basis?
If you have multiple revisions, they are described in the proj.qpf file, which just names the revisions.
The Revision.qsf files stay in the same directory as the .qpf file.
The ./db and ./incremental_db directories are placed at the same level as the .qsf(s) and .qpf, so you have db directories that are shared by multiple revisions. Common elements seem to get common names, and revision-specific elements seem to be prefixed with the revision name, which helps keep things straight.
However, occasional tool problems and the desire for repeatable compiles sometimes require deletion of ./db and ./incremental_db.
If there were a link after each revision entry (in the .qpf file) that could point to a specific directory, then each revision and its .qsf file and ./db and ./incremental_db could exist completely separate from each other.
I have found that sometimes the "Revisions" feature is useful for working on subblocks (in a bottom-up flow, generating .qxp files) instead of just using it to make variations of the same block.
I can do this with some extra Tcl/csh scripts, but would prefer to do it entirely from within Quartus.
I've gotten something like this to work partially using the "Create Bottom-Up Compile Scripts" but haven't fully understood all the flow and implications yet.
If anyone has experience with this, please share.
Many thanks!
