Abstract
An interleaved signal carry structure includes a first signal line and a second signal line forming a first bus. A third signal line and a fourth signal line form a second bus. A first set of carry function generators are positioned between the first signal line and the third signal line. Carry-in signal lines are attached to the first set of carry function generators. A second set of carry function generators are positioned between the second signal line and the fourth signal line. Intermediate carry signal lines are positioned between the first set of carry function generators and the second set of carry function generators. Carry out signal lines are attached to the second set of carry function generators. A first vertical carry chain comprises a first carry function generator from the first set of carry function generators and a first carry function generator from the second set of carry function generators. A second vertical carry chain comprises a second carry function generator from the first set of carry function generators and a second carry function generator from the second set of carry function generators.
