Sum of Products
Each Virtex-II slice has a dedicated OR gate named ORCY,
ORing together outputs from the slices carryout and the ORCY
from an adjacent slice. The ORCY gate with the dedicated
Sum of Products (SOP) chain are designed for implementing
LUTs and MUXCYs can implement large AND gates or
other combinatorial logic functions.

large, flexible SOP chains. One input of each ORCY is con-
nected through the fast SOP chain to the output of the previous
ORCY in the same slice row. The second input is connected to
the output of the top MUXCY in the same slice, as shown in
