摘要

Parallel SystemC approaches expect a thread-safe and race-condition-free model from the designer or use a compiler which identifies the race conditions. However, they have strong limitations for real world examples. Two major obstacles remain: a) all the source code must be available and b) the entire design must be statically analyzable. In this paper, we propose a solution for a fast and fully accurate parallel SystemC simulation which overcomes these two obstacles a) and b). We propose a hybrid approach which includes both static and dynamic analysis of the design model. We also handle library calls in the compiler analysis where the source code of the library functions is not available. Our experiments demonstrate a 100% accurate execution and a speedup of 6.39× for a Network-on-Chip particle simulator.
