SITARe: A simulation tool for analysis and diagnosis of radiation effects

This work provides reliability criteria to detect and diagnose multi-events upset by the use of a SER tool. The study is based on a charge generation model used to simulate the impact of an ionizing particle striking the sensitive nodes of a SRAM cell. The currents, collected at the sensitive nodes are generated by the physical model and injected at circuit level. Thus, a correlation between the circuit electrical behavior and injected currents is established to provide a reliability criterion.
