Abstract

FPGAs are widely used in space, aerospace, and defense systems for mission-critical control, communication, and on-board processing tasks. However, radiation effects such as Single Event Upsets (SEUs), Single Event Transients (SETs), and configuration memory corruption pose a significant challenge to FPGA reliability. This hands-on tutorial presents practical RTL-level techniques to harden FPGA designs against radiation, focusing on methods that engineers can directly implement and verify. Participants will gain insight into TMR, safe FSM design, error detection and correction (EDAC), temporal redundancy, and configuration memory protection. Through RTL simulation and live demonstration, attendees will see fault injection and mitigation in action, understanding the impact of radiation-induced errors and how hardened designs recover automatically. The session also introduces verification best practices, including fault injection strategies and radiation-aware testing. By the end of the tutorial, participants will have actionable templates and a clear methodology to develop and validate robust FPGA designs for SPACE applications.
