Fault tolerance evaluation study of a RISC-V microprocessor for HEP applications

Abstract

The utilization of a radiation-hard microprocessor or a System-on-Chip (SoC) design methodology significantly benefits the future design of ASICs for HEP experiments. To evaluate the fault tolerance of a radiation-hard design, it is important to obtain detailed information on the soft error rate and contributing factors. This article presents a simulation-based approach to investigate the effects of faults induced by single event transients in a microprocessor based on the open RISC-V instruction set architecture.
