Soft Error Reliability Aware EDA
No full textThis review explores advancements in GPU-accelerated EDA tools, such as DREAM Place and GPU-based Rectilinear Steiner Tree generation, which leverage AI and parallelism to optimize placement, routing, and logic synthesis tasks. These tools significantly reduce runtime and enhance placement accuracy, facilitating faster design iterations and improving fault tolerance by minimizing soft error hotspots. Additionally, AI-driven frameworks, including deep learning-based layout optimization, show promise in addressing pin density challenges, congestion, and manufacturability constraints. While these innovations enhance performance, gaps remain in ensuring radiation-hardened reliability for aerospace and military applications. Existing research primarily focuses on optimizing computational efficiency, but further investigation is needed into integrating fault-tolerant microcontroller design within AI-accelerated EDA workflows. Specifically, challenges in mitigating Single Event Upsets (SEUs) and enhancing real-time processing capabilities for mission-critical hardware require deeper exploration. Future work should focus on bridging the gap between AIdriven optimization and the development of robust, radiation-resistant microcontrollers to ensure reliable operation in extreme environmentshttps://digital.library.ncat.edu/gradresearchsymposium25/1185/thumbnail.jp
High-Performance Journal Shaft Design for Extreme Altitudes
No full textDeveloping robust mechanical components for high-stress environments is a significant challenge in the aerospace industry. Traditional journal shafts struggle with structural integrity and lubrication at elevated rotational speeds and altitudes. Our solution introduces a self-pumping journal shaft with a taper, designed to enhance lubrication retention and minimize friction during highspeed operations. The taper ensures a precise fit, improving alignment and reducing slippage, crucial at altitudes around 50,000 feet. By incorporating fluid physics principles, the design optimizes hydrodynamic flow within the shaft, ensuring continuous lubrication and efficient bearing performance at high RPMs. The self-pumping feature leverages fluid dynamics to maintain lubrication, reduce wear, extend the lifespan of mechanical systems, and minimize downtime. Our research emphasizes the importance of lubrication and alignment for enhancing durability and efficiency in journal shafts. This innovation addresses the specific challenges of high altitudes and high rotational speeds, making it especially impactful for aerospace applications. Enhancing lubrication and bearing efficiency, our advanced journal shaft design improves aircraft system reliability and efficiency, sets new industry standards, and offers significant economic benefits to the multibillion-dollar aerospace sector.https://digital.library.ncat.edu/gradresearchsymposium25/1189/thumbnail.jp
