Abstract
In order to aid quality assurance of large complex hardware architectures, system simulators have been developed. However, such system simulators do not always accurately mirror what would happen on a real device. A significant challenge in testing these simulators arises from the complexity of having to model both the simulation and the infinite number of software that could be run on such a device. Our previous work introduced SearchSYS, a testing framework for software simulators. SearchSYS leverages a large language model for initial seed C code generation, which is then compiled, and the resultant binary is fed to a fuzzer. We then use differential testing by running the outputs of fuzzing on real hardware and a system simulator to identify mismatches. We present and discuss our solution to the problem of testing software simulators, using SearchSYS to test the gem5 VLSI digital circuit simulator, employed by ARM to test their systems. In particular, we focus on the simulation of the ARM silicon chip Instruction Set Architecture (ISA)
