Abstract

Field-Programmable Gate Arrays (FPGAs) have emerged as best option for d i g i t a l circuit implementation over the last few decades. FPGAs have the ability to reconfigure at runtime; therefore provide opportunities to overcome issues like reliability and availability which are the serious issues in safety critical applications. This review attempts to investigate some of popular methods in fault detection and also gives an overview of partial reconfiguration technique in FPGA based systems.
