Abstract

The state-of-The-Art SRAM FPGAS show great potentials for aerospace applications because of their high performance, low power consumption and flexible configuration features. However, as typical CMOS devices, SRAM FPGAS are prone to Single Event Latchup(SEL) which may cause permanent damage to the device in the space radiation environment. This paper proposes a restorable anti-SEL method for SRAM FPGAS. The method can immediately disconnect the power supply when SEL occurs and restore power supply after the fault is solved. The experiments results show that the method can accurately detect the occurrence of SEL, and effectively release the SEL. Thus, it can help to improve the stability and reliability of SRAM FPGAS space application.
