Abstract :
To achieve fast verification of the software part of an embedded system, we propose to run the target processor optimistically, which effectively reduces the synchronization overhead with other simulators. For the optimistic processor execution, we present a processor execution platform and state saving/restoration methods. We performed optimistic execution of ARM710A processor in the coverification of an IS-95 CDMA cellular phone system and obtained up to orders of magnitude higher performance compared with the case that the processor runs conservatively
