Carry Chain Length logic option
A logic option that specifies the maximum allowable length of a
chain of both user-entered and Compiler-synthesized
CARRY_SUM
buffers. Carry chains that exceed this
length are broken into separate chains. (This option also applies
to MAX+PLUS II-style CARRY
buffers.)
This option must be assigned to a design entity or it is ignored. This option is available for all Intel devices except MAX3000, and MAX7000 devices.
