The Quartus II Compiler automatically creates carry chain logic during
design processing, or you can create it manually during design entry.
Parameterized functions such as LPM functions automatically take
advantage of carry chains for the appropriate functions.
The Quartus II Compiler creates carry chains longer than 16 LEs by
automatically linking LABs in the same column. For enhanced fitting, a
long carry chain runs vertically, which allows fast horizontal connections
to M4K memory blocks or embedded multipliers through direct link
interconnects. For example, if a design has a long carry chain in a LAB
column next to a column of M4K memory blocks, any LE output can feed
an adjacent M4K memory block through the direct link interconnect.
Whereas if the carry chains ran horizontally, any LAB not next to the
column of M4K memory blocks would use other row or column
interconnects to drive a M4K memory block. A carry chain continues as
far as a full column.
