This paper presents the design and implementation of a time driven adder generator architecture. There exists a large variety of adders designed to satisfy different computation requirements, in particular we list the Carry Look Ahead (CLA) adder, the skip adder, the ripple adder, the carry select adder (CSA), etc. These different architectures will offer different delays and it is up to the user to chose among them. The design we present here allows the parametrization of the architecture to fit ones design constraints. From the word length and the wanted delay the generator outputs a suitable architecture.
