What is the main difference between the clock-driven and event-driven simulation? 42. (Part 14, difficult)105-W4
A. In a clock-driven simulation, the network is updated after a fixed timestep, while in an event-driven simulation, the network is updated when a significant event (e.g. spike input) occurs.
B. The clock-driven simulation is mathematically identical to the event-driving simulation and they produce exactly the same result.
C. The differences between the two methods become not significant when the timing of individual spikes is important.
D. The event-driven simulation is faster than the clock-driven one in a network when the firing rate of the network becomes very large.
