Hi,
I'm using Vivado 2014.3 and I have this warning when synthesizing my project:
[Netlist 29-101] Netlist 'aes128_fast' is not ideal for floorplanning, since the cellview 'aes128_fast' contains a large number of primitives. Please consider enabling hierarchy in synthesis if you want to do floorplanning.
What does it mean exactly? And how do I enable hierarchy in synthesis? I don't find any such setting.
Thx.

Hi,
Set the flatten_hierarchy to none in synthesis settings to preserve the hierarchy.
Thanks,
