Efficient Physical Design Techniques for High-Speed, Area-Optimized 12x12 Multiplier Using CSA

Abstract

Designing a high-speed, area-efficient 12-bit by 12-bit multiplier architecture tailored for performance-driven digital systems. Traditional multiplication schemes often encounter challenges in minimizing computational delay and silicon footprint simultaneously. The proposed design adopts a carry save addition (CSA)-based array multiplier structure, which effectively reduces carry propagation delay by deferring carry processing to the final computation stage. The implementation utilizes CMOS-compatible components, including dynamic flip-flops and optimized logic cells, to achieve a compact layout. Furthermore, hierarchical design strategies and advanced physical layout techniques are employed to improve signal integrity and manufacturability. The resulting multiplier demonstrates notable enhancements in speed and area efficiency, making it a strong candidate for integration into high-performance digital processing architectures.
