Research on diagnostics and prognostics of FPGA-based system

FPGAs are widely adopted in many application domains and the higher accuracy requirement of FPGA makes the diagnostics and prognostics techniques of FPGA-based system is becoming increasingly important. This paper takes the stuck-at fault of look-up table in programmable logic blocks as a research object and presents the diagnostic method based on the Built-in Self Test. Example is provided for the approach and some basic physics of failure models are given to estimate the damage to the FPGA.
