Simulation speedup offered by distributed parallel event-driven simulation is known to be seriously limited by the synchronization and communication overhead. These limiting factors are particularly severe in gate-level timing simulation. This paper describes a radically different approach to gate-level simulation based on a concept of temporal rather than conventional spatial parallelism. The proposed method partitions the entire simulation run into simulation slices in temporal domain and each slice is simulated separately. With each slice being independent from each other, an almost linear speedup is achievable with a large number of simulation nodes.
