Enhanced System-Level Single Event Effects for Space Weather Operations

For this proposal, Fifth Gait plans to develop enhancements to system-level single event effects for space weather operations. Integrating system-level modeling into the Space Ionizing Radiation Environment and Effects (SIRE2) family of tools would provide a seamless environment and system-level modeling tool to the community. The proposed work is designed to provide the capability to perform system design calculations more quickly, which enables new workflows. Integrated environment and system failure calculations will allow the system designer to iterate though a larger number of radiation environment scenarios and a larger number of system designs. The Fifth Gait team will investigate system-level probability of survival capabilities to identify the current workflows used by the community and evaluate how the workflows fit inside the SIRE2 family of tools. The evaluation will include prototyping the different workflows to assess the potential feasibility of each one. Fifth Gait will also develop an effects categorization capability to calculate the upset rate inside a simulated electronic board or package. The categorization capability will include the peak effect for the board or package at each timestep in a trajectory. Finally, the Fifth Gait team will investigate SEE models to assess each model for their potential integration into the SIRE2 family of tools during a Phase II effort. The Petersen Figure of Merit model will be added to the SIRE2 family of tools to estimate the SEE rate.
