Hi Brian,

This is a big topic and is not new and is sensible.
The current build system was based on the "3rd party IP" or "Incremental
compilation" model (as Altera used to call it).
It is optimized to avoid rebuilding and resynthesizing lots of pieces
that add up to the design.
There is some sacrifice in some possible optimizations across synthesis
boundaries.

It is not optimal in the time it takes for building the whole design
from scratch.

There has been discussion on adding the option to flip things the other
way, and allowing building from all source code in one shot.

We do in fact carry the source code through the process behind the
scenes, so it is not a giant challenge.

Can you describe what drove you to ask and what benefits you were
looking for?  That will help prioritize this issue.

Jim
