and Spartan-XL families, speeding up arithmetic and count-
ing functions.
The carry chain in 5V Spartan devices can run either up or
down. At the top and bottom of the columns where there are
no CLBs above and below, the carry is propagated to the
right. The default is always to propagate up the column, as
shown in the figures. The carry chain in Spartan-XL devices
can only run up the column, providing even higher speed.

outputs connect to the function generators, where they are
combined with the operands to form the sums.

The fast carry logic can be accessed by placing special
library symbols, or by using Xilinx Relationally Placed Mac-
ros (RPMs) that already include these symbols.
