on a couple of designs. With the
test case I still make timing and there's about 2000 less cells overall. It looks like yosys is pretty aggressive at adding buffers. Is it worth adding to the flow?

and User is with
. There is a general increase in the wns; however, it's a slight increase -5ns max. On the other hand, the antenna violations and the wire length got reduced significantly for most designs as well as the runtime to route. I think this is something to consider adding to the flow at least if optionally. What's your opinion about that @Anton Blanchard & @Ahmed Ghazy? I haven't tried disabling
from the start, still waiting on some computing resources to be available and then I'll give this one a shot.
