Abstract
In this thesis, we proposed a novel simulation scheme, called data-dependency-aware synchronization and scheduling, for SoC virtual platform simulation. In contrast to the conventional clock-based or transaction-based synchronization, our simulation scheme works with the clock decoupling and direct-data-access techniques to implement the trace-driven virtual synchronization methodology. In addition, we further extend the virtual synchronization concept to handle the interrupt signals in the system. This enables the porting of operating system in the virtual platform. We realize our simulation scheme of the data-dependency-aware synchronization and scheduling by implementing a simulation wrapper on top of the SystemC kernel. The experimental results show that virtual platform can achieve 3 to 5 million-instructions-per-second simulation speed, while still maintaining the same cycle-count accuracy, which is around 44 times speed-up over the conventional cycle accurate approach of SystemC kernel.
