Abstract:This paper presents the design and implementation of a 64-bit full adder using the SkyWater 130nm Process Design Kit (PDK) and open-source electronic design automation (EDA) tools. The purpose of this research is to develop a highly efficient arithmetic unit suitable for integration in modern digital systems. Utilizing the open-source tools such as Magic-VLSI for layout design, Xscheme and NETGEN for schematic, this paper demonstrates a streamlined design process that underscores the potential of open-source EDA solutions. The designed 64-bit full adder was rigorously tested, and performance metrics were evaluated. The final implementation demonstrated a significant improvement in power efficiency and speed compared to existing designs, with a power consumption of 1.66 uW and a propagation delay of 2.54ns. These results validate the effectiveness of using open-source tools in advanced digital circuit design and highlight the viability of the SkyWater 130nm PDK for high-performance applications.
