| Description: |
Microcontrollers running safety-critical applications with high integrity requirements must provide appropriate safety measures to manage random hardware faults. For instance, automotive safety regulations (e.g., ISO26262) impose the use of diverse redundancy for items at the highest automotive safety integrity level (ASIL), ASIL-D. In the case of computing cores, this is realized with dual core lockstep (DCLS). The advent of the RISC-VISA has made open source hardware gain popularity. However, there are few industrial open source SoCs meeting the requirements of safety-critical systems, and, to our knowledge, none of them provides lockstep cores. This paper presents the realization of a RISC-V open source lockstep core based on Gaisler's NOEL-V core for the space domain, as well as its integration in the SELENE SoC that provides a complete microcontroller synthesizable on FPGA successfully assessed against space, automotive and railway safety-critical applications in the past. ; This work is part of the European Union’s Horizon 2020 Programme under project KDT Joint Undertaking (JU) under grant agreement No 101112274 (ISOLDE). This work has also been partially supported by the Spanish Ministry of Science and Innovation under grant PID2019-107255GB-C21 funded by MCIN/AEI/10.13039/501100011033. ; Peer Reviewed ; Postprint (author's final draft) |
