Predictive parallel event-driven HDL simulation with a new powerful prediction strategy

Traditional parallel event-driven HDL simulation methods suffer heavy synchronization & communication overhead for timely transferring the signal data among local simulators, which could easily nullify most of the expected simulation speed-up from parallelization. A new predictive parallel event-driven HDL simulation as a new promising approach had been proposed for enhancing simulation performance. In this paper, we have further enhanced this noble parallel simulation method for a series of not only timing, but also function oriented design changes with a new powerful prediction strategy. Experimentation with real SOC designs from industry has been performed for actual design changes, and shown the effectiveness of the enhanced approach.
