Abstract: The single event effect (SEE) test system is developed for the SEE evaluation for a domestic ASIC (application specific integrated circuit) used on the space satellite. The single event upset (SEU) data under irradiation of the Kr ion are obtained for the SEE evaluation test. The fault tree analysis and circuit emulation technique is adopted in the simulation for the SEU, and the SEU sensitive module is located inside the ASIC, which provides a basis for the system-level radiation hardening design of satellites and the follow-up design for the IC designer.
