description: The work involved analyzing emerging failures, studying existing protection methods at the structural-behavioral level, and proposing methods to protect registers of the device. A vulnerability index was defined and a method for evaluating it was introduced. To assess the vulnerability factor of the original device and the modified device, a fault injection tool was developed. Based on the analysis of the original device and the vulnerability values obtained, a strategy was developed and implemented to protect the registers of the controlling pipeline stages. Timing analysis was performed after the modification, confirming that the applied methods did not degrade the deviceâs time characteristics. The results of this work represent a separate part of the design flow for the adaptation of the NOEL-V processor core for use in environments with increased ionizing radiation.
