Carry Chain
The carry chain provides a very fast (as low as 0.2 ns) carry-forward
function between LEs. The carry-in signal from a lower-order bit drives
forward into the higher-order bit via the carry chain, and feeds into both
the LUT and the next portion of the carry chain. This feature allows the
ACEX 1K architecture to efficiently implement high-speed counters,
adders, and comparators of arbitrary width. Carry chain logic can be
created automatically by the compiler during design processing, or
manually by the designer during design entry. Parameterized functions,
such as LPM and DesignWare functions, automatically take advantage of
carry chains.
Carry chains longer than eight LEs are automatically implemented by
linking LABs together. For enhanced fitting, a long carry chain skips
alternate LABs in a row. A carry chain longer than one LAB skips either
from even-numbered LAB to even-numbered LAB, or from odd-
numbered LAB to odd-numbered LAB. For example, the last LE of the
first LAB in a row carries to the first LE of the third LAB in the row. The
carry chain does not cross the EAB at the middle of the row. For instance,
in the EP1K50 device, the carry chain stops at the eighteenth LAB, and a
new carry chain begins at the nineteenth LAB.
Figure 9 shows how an n-bit full adder can be implemented in n +1 LEs
with the carry chain. One portion of the LUT generates the sum of two bits
using the input signals and the carry-in signal; the sum is routed to the
output of the LE. The register can be bypassed for simple adders or used
for an accumulator function. Another portion of the LUT and the carry
chain logic generates the carry-out signal, which is routed directly to the
carry-in signal of the next-higher-order bit. The final carry-out signal is
routed to an LE, where it can be used as a general-purpose signal.
