Regarding the LSI soft error caused by the neutron beam, a single particle of neutron may cause multiple chained soft errors at once. Consequently, in order to reduce the total soft error damage, it is necessary to know the extent of the multiple chained soft errors. In the measurement of the extent, some acceleration experiment is indispensable, and it is required to detect the error bit location(s) as soon as possible after the soft errors occur. Conventional SRAMs, however, need long scanning time to locate the error bit(s). Therefore, we propose a novel LSI structure specified for the chained soft errors measurement and its measurement methodology. We fabricated an emulator of the LSI and its controller LSI using FPGAs, respectively. In the experimental measurement, it was demonstrated that the emulator reduced the location detection time of a soft error by 1/4000 compared with the conventional method. |
