——Energy-efficient fast adders are needed in the design of battery-powered portable devices. Although many fast adder architectures exist, most of them require transistor-level optimizations that prevent their synthesis in a standard-cell flow. This paper presents two energy-efficient Add-One Carry-Select Adders (A1CSA and A1CSAH) suited for standard-cells(More)
As the interconnections dominate the circuit delay in nanometer technologies, placement plays a major role to achieve timing closure since it is a main step that defines the interconnection lengths. In initial stages of the physical design flow, the placement goal is to reduce the total wirelength, however total wirelength minimization only roughly(More)
