Incremental compilation and NIOS - Bottom Up

All the sopc is what is partitioned.

I've created exactly what you told: a wrapper file that is on the main project.

But when I've imported the .qxp it ask me only that files because it tell that it is encrypted.

As workaround with the .qxp the other people give me the CPU_Supervisor.vhd that I put in the main directory of my project.

I think that the problem went up only because I've told quartus to import the netlist and not the place and route, now I've fixed the partition also with logic lock and exported that in the "Nios" project and use the place and route (but I'll see that tomorrow, because each compilation is almost 1h of time).

Thx Risc for the suggestion and for advice for potential drawback.

We've chosen this way because in the "Sopc project there are also some other files created by the megawizard and in nios you've to specify the directory and a lot of time we've problem because we copy the directory of the project, then we change some IP in the new directory but the Sopc go for the old one (you can't give relative assignment, but you've to give the full directory name).

I'll keep to update the thread with what I discover.
