Incremental Compilation and SignalTap

Hi all, My understanding is that we cannot preserve the placement & routing if we create a new partition under the top-level design (which is a partition by default). In this case, how does the...

I am usually most interested in part b), where I would need to preserve the P&R of the entire design. In many cases particularly in huge design, when I set the top partition to post-fit and recompile, I would face fitter error, usually indicating resource conflict or not being able to satisfy hard routing constraints. This prevents me from preserving the netlist of the design.

I presume if I do not set the top-partition to PostFit but add Postfit STP, only the tapped signals will be preserved, but the rest of the design is still free to move?
