This paper presents an optimized channel usage between simulator and accelerator when the simulator models transaction-level SoC while accelerator models RTL sub-blocks. Conventional simulation accelerators synchronize the progresses of simulator and accelerator at every simulation time, which results in poor performance by splitting transactions on the simulator-to-accelerator channel into pieces. Occasional synchronization with predictions and recoveries makes it possible to merge multiple transfers yielding substantial performance gain compared to the conventional method.
