Design and Comparative Analysis of High Speed and Low Power ALU Using RCA and Sklansky Adders for High-Performance Systems

This study examines how different initial design decisions affect the area, timing, and power of technology-mapped designs. ASIC flow, tools used during factors to consider maximize performance ratio are discussed. The ALU (Arithmetic Logic Unit) is a fundamental part all processors. In this study, two ALUs were implemented using types adder circuits: Ripple Carry Adder (RCA) Sklansky adder. Cadence EDA for implementation. A comparative analysis was conducted designed in terms power, timing analysis. also as an example examine whole workflow front-end wise by constructing block schematic back-end floorplanning, placing, routing physical design.
