FastLUT Interconnect
Mercury devices include an enhanced interconnect structure within LABs
for faster routing of LE output to LE input connections. The FastLUT
connection allows the combinatorial output of an LE to directly drive the
fast input of the LE directly below it, bypassing the local interconnect. This
resource can be used as a high speed connection for wide fan-in functions
from LE 1 to LE 10 in the same LAB.
